RS 175-U Digital Wireless TV Headphones

First let me say that I suffer a serious hearing loss which makes it difficult to watch television with my wife because I have to have the volume up so loud and even then I can't hear everything. I have had two sets of sennheiser RS 120's for a few years now and loved them. My wife wanted to get me these for Christmas this year because they were apparently capable of surround sound. Now I'm not an audiophile but I will try to point out some pro's and con's here. The 175's are an over the ear fit as opposed to the 120's being an on the ear fit. The 175's fit much tighter which is very nice when up and moving about yet the tight fit makes it difficult to hear when my wife is speaking to me during a show which she does quite often. I'll let you decide if that's is a pro or a con. The 120's were loose enough that I could hear her speak even though I still had to remove the headset to understand her. The looseness had a downside though in that if I went to the fridge for a drink or snack and bent down the headset fell off. Not so with the 175's. Both sets have excellent sound reproduction even though the 120's are analog. The 175's can be digital or analog which can be decided by a switch on the back of the transmitter. You have the option of connecting to the sound source by optical cable or 3.5 jack which in my case required a y adapter converting to RCA jacks. I was amazed to find that there is a very noticeable difference between digital and analog, digital being the best by far. With the digital you don't hear any static or interference noises in non-dialog or silent spots. At least I couldn't hear any and my wife said in her words "this is fantastic". sound with the 175's: You can switch between regular stereo, low SRS, and High SRS by clicking a button on the side of the headset. This can also be controlled at the transmitter. There is a very noticeable difference between each setting. I have noticed that on low SRS the background recordings seem to be moved back and reduced in volume while the main dialog remains at regular volume. Ever had one of those instances where the main character is talking in a whisper voice, which seems to be in vogue these days, and is suddenly overrun by the background noise, which also seems to be a problem these days. Well, low SRS helps to overcome that problem for me. I can hear the dialog very clearly and if you've lived for a while having to constantly asked "what did he/she say?" then you can really appreciate that fact. In High SRS there is a distinct surround sound quality. I've never been able to experience this before due to my hearing loss so to me it is awesome. I love Paul Simons music, especially "Graceland", "father and daughter" and "late in the evening". I just thought I liked them before but after listening to them through the 175's I have heard notes and instruments that I didn't realize were there. Now I love the songs. Having discovered that I went back and watched a couple of my favorite movies and discovered background sounds that I had been missing and they add so much more to the entertainment value. Keep in mind that I have experienced all this with the 120's also and there is a large difference. continued pros sound aside: I like that the controls are on the side of the 175 headset because I often recline when watching television and this keeps the controls from contacting anything and changing the settings unintentionally. This was a problem with the 120 sets because the controls were behind the headset. The 175 set, to me, is much more comfortable because of the padding and because possibly of the tighter fit which keeps them in place verses the loose fit of the 120 set. cons (maybe): The 175 set is only capable of employing two headsets. The 120 can employ several at one time. I'm not sure how many but certainly more than four because I have that many headsets. The 120 has an option of three channels selectable on the transmitter and the headset which means you can use more than one in a household without interfering with each other. This is the situation at my house. I have one set in the bedroom and one in the living room and we can use them separately on separate channels at the same time. My grandkids love the headsets so this settles a problem when they come to visit and want cartoons while I want news. The 175 has only one channel so this setup would probably not be possible. The 175 power button has to be held down for about three seconds to activate while the 120 has a slide switch. The 175 has a very slight delay between activation and transmitter connection. The 120 is instant. This caused a rather humorous incident early on. My wife was watching a movie on Netflix and I picked up the headset, turned it on, placed it on my head and thought I was waiting on a connection when in reality I was in a very quite point in the movie just before an explosion and massive gunfire. I was on my way to my recliner when all hell broke loose and it was so realistic I almost wet my pants and overran the recliner. It was apparently the highlight of my wife's day. She still laughs about it. Her lack of concern about my bruised shins and ego aside...after the fact it was funny. I know this was lengthy but I hope it helps someone in my situation to make an informed decision. In short I would never had purchased the 175's for myself due to the cost because I wouldn't have believed they would make this much difference. Now that I've experienced them I would buy them in a heartbeat. Now a word about sennheiser's customer service. I had a situation early on where I lost the optical connection with my TV. I was quick to blame the new headset simply because they were new. I sent an email to sennheiser in hopes they could find a solution before I had to send the set back. I had a return mail in about 45 minutes telling me what to do. Turns out the problem was with the television and not the sennheiser transmitter. Quick response, great customer service.

I bought these to replace a pair of Sony MDR RF-6000s and use them mostly for TV/Movies. The Sonys cut out and picked up lots of interference from wifi and other 2.4ghz traffic (I live in a city environment with easily 25 wifi networks in range). Overall, they've been great and are well worth the money. Signal: So far, the Sennheisers have been flawless with no dropouts or signal loss. As above, I live in a pretty interference-heavy environment. Haven't really range tested them, but they'll easily go into the next room with no problem. Sound Quality: I played around with the bass boost and surround, but find things sound best with all that off. There's no shortage of bass and sound quality is full and on par with any high-end headphone from Bose, Sennheiser, or Sony. There's a slight signal delay, though that's only perceptible when the audio is also playing through speakers, and I'd expect that from any RF headphones. Batteries: I haven't tested the battery life yet (had them on a couple hours and no issues). They use rechargeable AAA batteries, which allows for the use of standard AAAs if the rechargeable ones die. Each earcup has a battery, accessible by twisting/unlocking the pad. That evens out the weight, but adds a step to change batteries. Cradle/Transponder: It's a pretty sleek looking stand, both with the phones on and off. Takes a little bit of practice to get them on and off just right, but nothing too difficult. Comfort: They're a pretty tight fit, which is good for keeping them on while moving around, though maybe not the best for all-day listening. All considered, no complaints about comfort. My only long-term concern would be the foam pads on the headband - foam tends to wear and these don't look replaceable. The headband is a standard adjustable model, though a bit thicker than some others due to the larger size and weight of the electronics/batteries. The Sonys had a band that turned them on automatically when you put them on (and then beeped annoyingly if there was no signal). These use a button for on/off, which is slightly less convenient but more durable and reliable long term. You have to hold the button for a few secs, so they aren't prone to accidentally being turned off. In all, these are a good buy and decent balance between price and quality with no significant flaws. My main driver is signal quality in a high-interference environment, and these have certainly solved that so far. Also, the packaging and instructions were easy and clearly well thought out. That's often an afterthought, but a bad experience there can set the tone for the product long term. Nice work, Sennheiser. UPDATE: 10 Months in, and these are still going strong. Battery life is still excellent - I've had a few "marathon" sessions (use these for TV) and they've yet to run out. Often, I get lazy and don't throw them back on the charger after an evening of TV and they're still good to go the next time. In our old place, I finally found where the signal would cut out - in the basement three floors down. Our new house is lath and plaster, which is murder on all kinds of wireless signals, and they're good for about one floor in either direction and probably 70-80 ft from the base station. Unless you live with lath & plaster (and you'll know if you do) or in a stone castle, I can't imagine a scenario where you wouldn't have whole-house roaming. Still never had even a blip of interference, despite a neighborhood of wireless routers screaming at high volume in 2.4ghz. UPDATE 2: Almost 4 years on and these are still performing as they did when new. I did wear through the earcups (every headphone I've ever had does this) and easily replaced them with no tools - it's a twist-lock change. Original batteries still going strong with almost-daily usage. UPDATE 3: 5 years in. Just replaced the headband pads (peel off old ones and stick on new ones). Replacements available for ~$19 on Amazon. Battery life and sound quality still as it was in the beginning. UPDATE 4: I have owned these for almost 9 years and still use them almost daily for evening TV. Just changed the earcup pads again. A couple years ago the original batteries failed to hold charge, so I swapped with AAA rechargeables from Amazon - no discernable difference in use or charge time. So few technology things fit the "buy it for life" model, but these might be the ones.

From my initial experience with these, they are absolutely phenomenal! The sound is crystal clear, and the bass is impressive, with 2 options to choose from; great bass, or extreme bass! The surround sound is a cool added bonus too, with two levels to choose from. Now the issues... First of all, I just want to say, the setup was super simple and awesome. I used the Digital Optical Audio Toslink Cable that was included in the box and connected it directly from my TV's Digital Optical Audio out to the Sennheiser dock for the best audio connection possible. I completed the setup process as per the quick start manual, and let it charge for half a day before trying them out. They worked great, and the sound exceeded all my expectations. Where the problem started was if I accidentally pushed the power button (while powered on) or even intentionally pushed it, like a typical button instead of holding it in to power it off, the audio would disappear yet the device would remain powered on. I know the manual says to hold it in for several seconds to power on or off, but sometimes you might accidentally push it, like when adjusting them on your head, or even when getting used to how they operate you might inadvertently push the button to power it off only to remember you must hold it in... I first thought that maybe it was a cool additional feature to mute the audio without powering them off, but pushing the button again did not bring the audio back, in fact no button would bring the audio back. The first time this happened I simply powered them off completely and then back on and I was good to go. However, twice since then I have accidentally pushed the button and lost audio, and powering it off and on wouldn't even bring it back. With my luck, this would usually happen just as I was beginning a movie or TV episode, and I was unable to get audio back for the duration of that use, having to resort to using my Bose sound system and watch the volume carefully. Each time I've encountered this issue I have ended up leaving the headset powered off on the charging dock, and the next day when I went to use them they worked just fine. I read completely through the operation manual several times trying to find anything on whether it was a mute function or used as something different aside from powering on or off, and I found absolutely nothing! In fact there was there was very little to practically nothing in all the papers included in the box on the operation of the device aside from how to set up the dock and connect to your TV, and insert the batteries in the headset and power it on. I figure they assume everything else is straight forward when it comes to buttons; bass, surround sound, and volume control. That being said, I would assume that the power button would be the same, not finding anything to say otherwise, its sole purpose is to power the headset on or off. I don't know why I have this problem, but I'm quite sure it isn't a dead battery because they are brand new, and two of the times it has happened I had just pulled them off of the charging dock with the green light indicating they were fully charged, and these are supposed to have quite an impressive battery life that I probably could never completely drain in a single day.. Other uses that I didn't bump the button or run into this problem, I would use them for up to six continuous hours, ruling out the battery as being the problem. All I can figure is that it could be a faulty pair?? Aside from this one issue, if I am careful to not push the button until I am done using them for that setting, then I don't have any problems... And as I mentioned before, the sound is awesome! I have not yet reached out to Sennheiser for support, but I intend to when I get around to it. For now, this has been my experience with these, and I do intend to update my review if and when I resolve this problem.

Strengths Sound quality really good for wireless, the best i have heard in fact for wireless. Better than a lot of wired too, to my ears these sound wonderful. I have a lot of headphones and am into audio as well. I think the sound would suit the tastes of 90% of people. For movies these kill, got me though when my daughter was in infant :) They extremely conformable with easily replaceable pads. i upgraded to the felt pads you can buy the 185 pads and they work fine. They are better than the stock ones that come with these for those of us that like the feel of felt. Simply fun to listen to. Close as you will get to a 2k home theater on a budget. Really just want to cut to the chase these are fun to listen to, and i feel they sound wonderful for movies. I can honestly say i don't think they could be any better for this usage. Also love having replaceable batteries. I have had this for a couple years now, and a buddy has has his a previous model for more than 10 years old (180) so i know they hold up fairly well. Weaknesses They don't leak sound, but the sound isolation isn't the best as compared to some other over year phones i have tried. It isn't bad, just don't expect super isolation. The head band pad is not the best. Fake leather feels a little thin there too. The build is also not the most robust. I haven't had any issues but i am also really careful with my things. I wouldn't drop it. I'd be surprised if it could sustain a fall from 4-5 feet on a hard surface with out breaking. The price i paid for the full unit with the base station was 171. It is a buy at that price, no regrets, in fact i like the sound so much if i could find it for that price or lower i'd consider picking up a second done for work since i like it better than Bluetooth. while it isn't quite as flexible as bluetooth since you need this station, it performs better, and there are no hiccups with either lag, or bluetooth issues like jitter etc. In fact in all the years of owning this i have never had any issue audio or otherwise. I think 270 which i see from time to time is asking way too much though they are good but let's not be crazy. The mark up on head phones is absurd. I'd wait for a sale. For what these do they are wonderful. If you want a pair of cans for your home theater system or computer, and don't need as much flexibility as bluetooth provides and have a scenario where audio performance is paramount, you'll totally love these.It really is significant in terms of quality it is a rich sound, with a nice sound stage and imaging which helps for movies and games. While not perfect if I am being picky, after years of owning this i am giving it 5 starts because i still use it, and it has served me really well, and i have been totally satisfied with my purchase. In fact i used this and my Bluetooth cans more than any of the corded ones i have these days, and i have some nice ones. This sound just about as good as some of my high end cabled head phones especially for things like movies. They are particularly tuned for that. My main gripes are I would love to see 1.) more isolation, 2.) more robust build quality 3.) this quality of sound on Bluetooth if it is possible. I mean i feel like i have to treat these things like fine china which they are :) I can honestly say these'd would by far be my go to head phones in all scenarios if i could get this sound quality on Bluetooth and not paying 500 dollars.Here is hoping. These have great imaging and are almost as good as open back headphones in sound stage. there is almost a surround sound nature to them, but they just sound great. If you want uncompromising high end sounds for your movies in a head phones these are the ones to get.

These things are great! I was a little hesitant to pay so much for headphones, but I don't regret it. They sound great and the charge lasts a long time. I haven't run out of battery yet. The charging station is great. The headphones snap right into place when you put them on the station. Highly recommend.

April 19, 2022: Dropped rating from 4 star to 1! I bought a pair of what I thought were HDR 175 headphones. Looking at the site today, Amazon labels these as RS 175 RF Wireless Headphones, yet the photos show HDR 175. Why is this a problem? Because the product designation matters when pursuing a warranty or troubleshooting issue. I've purchased what I thought were HDR 175s several times at Amazon, and have loved the headphones. (See former reviews below). Having only the day before yesterday (April 17, 2023) unboxed and plugged in the headphones I purchased in September 2022, I noticed that after two full days of charging that the charging light is still red. I tested the batteries in the headphones, and they seem fully charged. It could be something amok with the status function of the charger, but I won't know until I get a response from a Sennheiser Support provider. Good luck navigating the internet and Sennheiser site for getting ANY information on HDR 175s. SInce Amazon calls these RS 175s, at least I was able to submit a support request once I finally found out where to do that. The Sennheiser Support site is a nightmare to navigate. The only hit I found anywhere regarding this issue was a review for the HDR 175s here at Amazon from a purchaser who had the same problem but reported that it magically solved itself a few days after he/she contacted Sennheiser and they responded. I love the headphones (with the exception of the flimsy padding on the ear and head pads.) and am dismayed that Support is so difficult to get. I wish I'd opened the box in September, so I could have returned the problematic headphones to Amazon. September 8, 2022 update. I still love these headphones. They are comfortable and provide exactly what I need by way of providing audio while watching TV. I prefer this version's method of powering on and off the headphones, vs the HDR 170, where I need to remember to turn the unit on at the base station before ALSO turning on the headphone. One problem with both models is the flimsy material that is used to cover the pads. I realize that replacement pads can be gotten for as little as $15, but that they need to be replaced every year or so, when used often, is ridiculous. The soft film covering the pads begins to disintegrate almost immediately. Can't SOMEONE come up with a better covering? Before ordering yet another pair of replacement pads for both units (HDR 175 and older HDR 170), I'm going to read reviews for later models to see if a better design exists. Still great unit. I dropped a point from my original review because of the need to constantly replace the pads. (by the way, it's not just the ear pads that disintegrate, but also the small rectangular pads that cushion the unit at the top of your head... Original review from 2017: I use these primarily because the family room TV is located in a very near the kitchen - center of activity in the house. My hearing isn't what it used to be and I need to have the option to basically shut out extraneous chatter. With these headphones on, I can watch TV while the family goes about their noisy routine in the kitchen. Later, when the kids are focusing on homework, I can turn the speakers on the TV off and still watch without disturbing them. I also own an older Sennheiser headphone system (the RS 170) as well as an even older Sony MDR RF970R. These are attached to TVs elsewhere in the house. In terms of sound quality in general, both Sennheiser systems clearly outperform the Sony. The Sony system just sounds tinny and can't compete on the bass side of the equation. While the sound quality between the Sennheiser systems is (to my ear) the same, the later system (the 175) fits more snugly and has a better system for turning the system on and for adjusting volume and other settings. The buttons on the 170's are really difficult to find when wearing them and the headphones don't hug your head very well. That's both a plus and a minus. You can wear them longer, but if you tilt your head, the headphones don't really stay put very well. If I cared to part with the cash, I'd have the 175's attached to all three TVs. Highly recommended.

After reading the reviews on these I was cautiously optimistic thinking that the bad reviews were by more likely user error. The optical connection is the way to go. I was looking for a way to listen to the TV without bothering the family. I have insomnia and I listen to something on headphones most of the night. I have been using Sony M3’s and M4’s for the last 10 years and was content that I had the best sound in the price point. Comfort is a big factor for me. The Sonys are comfortable for the long haul no doubt. The first time I put the 175’s on I thought this is not going to be a comfortable fit. They seemed clunky and ‘plastic y’. Then I realized that the large ear pieces were designed to go over the entire ear and seal against the skull. I’m 62 years old and have been through the audiophile generation. I appreciate good to great sound and demand it in my equipment without going broke. After I figured out the comfort issue I could turn to sound quality and user experience. I’m pleasantly surprised by the 175’s. They have range and depth sound quality. If I’m being completely honest they seem almost better than the M4’s. After the initial setup and charging time (a serious 12 hours) I began to put them through the paces. The 175’s passed all my quality checks. Bass boost definitely fills in the lows without muddying the sound. Surround setting gives some feeling of spatial fidelity. As far as watching TV you won’t be disappointed. I had forgotten about listening to soundtracks but these brought it back. I was pleasantly surprised by how easy it was to listen to my Pandora account on the TV. This is where these things really shine. With the optical connection sound is first quality. Have a Samsung 65” TV with a Samsung sound bar, it’s a newer model. Connections were a breeze Don’t not try these because of bad reviews. If you know your way around audio equipment and are not interested in spending too much I say give them a try If you’re looking for a good quality audio answer to watching TV privately and listening to music on your cable get these. If you want to spend more Sennheiser can also accommodate you. For me and my insomnia the 175’s are the answer

5 stars, but not quite perfect. The button necessary to turn the headset on/off (on one of the ear-cups) when you put the headphone on is a bit tricky to find in the dark; it's on the rim of one side of the headset ear cover and you find it without removing headset as you would use braille. Note that you must hold the tiny almost flush on/off button in for 3 seconds or so to accomplish task; one quick press will not do it; at first a bit annoying but probably a good feature to avoid an accidental bump resulting in no sound. The volume; sound control is done with 4 additional large buttons on the flat/outside of the same side ear-cover. These buttons (all nearly flush, which is fine- there's enough protrusion to find, not so much as to interfere with operation) have raised dots for sound quality on two buttons, and a + and a - for volume which are quite visible, but not as easy to distinguish by fingertip with the headset on. The single raised dot on the sound quality buttons should be doubled on one side (1 dot on one button, 2 dots on the other) since you will forget which button does what. The same controls are repeated on the base unit, but frankly, I have never had need to use these. The different shape of the ear covers is very useful to distinguish right from left by feel when you pick the headset up, as in the dark. I find the range as described is adequate but exaggerated. I had a similar Sony set before this and a similar (earlier) Sennheiser set before that and both gave substantially better range (say, walking outside to check on the weather or whatever). Sorry, I have not measured actual range, but I use this only for watching TV (my wife listens to the TV's sound bar +/Bose speakers, since we have much different hearing sensitivity: she hears like a bat; I hear like a post), but as I walk around inside house there are areas where I lose sound. I was a bit disappointed, but the loss is limited & acceptable if not ideal. Otherwise, the sound quality is super excellent (recall my hearing). I hear MUCH better with these than in our super new multiplex IMAX theater. For others with hearing problems, turning off the surround sound/bass boost features at times gives me more distinguishable dialogue; so being able to change modes may be a useful alternative for most people. The surround-sound is quite convincing; I use it or not, depending on the program. I have marathon-watched TV series or films and have never had a hint of battery weakening. The docking station is good looking and solid, never falls over from imbalance or a bump. I hope the ear pad material is an improvement over previous sets I have owned, which frayed long before the rest of the system showed wear. The ear fit & design are excellent, excluding all but loud ambient noise. When my wife and I are sitting on our long sofa, I cannot hear her normal speaking voice, but if she raises it just a bit, "Can you hear me?" I always answer, "Yes, I can," then loosen the fit on one side and can hear her fine. Overall, highly recommended.

Impressive wireless sound including surrond and base boost options.. Easy set-up and good connection to tv. Good quality built with good looks. A little pricey compared with Bluetooth options. Overall, happy with purchase.

Como cliente solo puedo decir que al comprar este producto lo hacia con la intención de brincar a una gama de de audio de verdadera calidad auditiva y de fabricación. Después de investigar un poco por Internet y Blogs especializados (Esto para no comprar solo por estética, por moda, o por economía) decidí que mis próximos audifonos serian de la marca: SENNHEISER, que por lo que investigue, es un sinónimo de calidad. Así que no me quería quedar sin probarlos. Al verlo en oferta, no dude. Ya una vez pedidos, como un buen humano comencé a dudar si realmente valía la pena la inversión. ▬ CONTRAS: - Debes saber que son audifonos enfocados en el uso domestico. No son para salir de casa o de viaje, ya que al ser audifonos Wireless no debes confundirlos a que son ¨Bluetooth¨, son dependientes del transmisor. - A un nivel alto de sonido, dejan escapar ¨algo¨ de sonido de manera que alguien cerca de ti puede escuchar que es lo que estas escuchando sin problemas. ▬ PROS: - Son sorprendentemente livianos, tanto el equipo como el transmisor. - El material de fabricación es de excelente calidad, se sienten resistentes y son muy cómodos. - Cumple a la perfección el alcance de la transmisión entre el transmisor y el equipo de audio. (Mi experimento me llevo a obtener 70 Metros sin interrupciones en la transmisión, incluyendo obstáculos en mi recorrido: casas, arboles, y una gran piedra) Sin duda cumpliría los 100 metros sin obstáculos entre el transmisor y los audifonos, que ofrecen para este equipo. -Aíslan el sonido externo de manera perfecta, puestos, y aun sin subir el nivel de audio a lo mas alto, dejas de escuchar a una persona parada frente a ti hablando. - El ultimo, y para mi, mas importante: La CALIDAD DE AUDIO. Para Música: El sonido es envolvente! La 1er de sus funciones, el SURROUND (Sonido a 360°) funcionan a la perfección. Me hizo sentir que escuchaba que tocaban en un cuarto (El Surround activado a nivel medio, sin ninguna configuracion de audio en mi celular) Activado a nivel alto me parecio el estar escuchando un concierto. La música muy viva; escuchas bien distribuido los instrumentos, una excelente acústica. Los probé escuchando diferentes tipos de música, desde Música Clásica, Jazz, Pop, Sesiones Acústicas, hasta electrónica y Hip Hop (Que aquí es donde utilice la 2da de sus funciones: El realce de BASS (Bajos). En resumen con estos audifonos pude percibir detalles que no había logrado escuchar con otros audifonos. Para Peliculas y Tv: Aun tengo la sensación de la granada que exploto a mi derecha en la película que vi el día de ayer. Me senti como en el cine literalmente. ▬ Después de esto espero y comprendas por que te puedo decir que valió la pena cada $1 invertido, supero mis expectativas por mucho y disipo las dudas que me habían surgido al invertir tal cantidad de dinero. - Marck Molina

These Sennheiser RS wireless headphones are multi purpose and not just for TV etc. They are also perfect and exactly what I was looking to connect to Analog/Phono i.e. a Fluance RT 85 Turntable. I connected the RS 175 base to the Marrantz model 50 Analog amp recorder outputs with a Jomely 3.5mm AUX to 2 RCA splitter cable from Amazon. I wanted the ability to listen to records when moving to another room without turning up the volume on the amplifier and disturbing the entire household. After doing my research these RS 175 wireless headphones appeared to be a perfect solution. I like everything about them. Affordale; Wireless; Comfortable; Analog to digital conversion; Seperate volume control; Bass boost; Surround mode; Charging base. Thank you Sennheiser and Amazon!

I tried RS 195 and did not like them. For me these RS 175 sound better. I use the optical connection from source (my PC), and these sound great at all volumes. There's no delay or lag unlike some Bluetooth. Great for gaming, movies, and music. I use surround sound feature for movies and it sounds really good. They auto shut down after 15 minutes too which helps save battery in case you forget to put them back on the headset to recharge. Batteries are also AAA rechargeable NiMH, and replaceable by the user. In my experience, the typical 850mHA batteries are fine and I think i get around 8-10 hours of use, but AAA batteries can be high capacity up to 1,100 mHA, and i think it would be worth it to get greater capacity at some point. When batteries level gets low there is an annoying beep.

Antes de usar estos audífonos usaba unos bose (no recuerdo el modelo) así que tenia una expectativa muy alta en cuanto a que esperar de los RS 175 y superaron mi expectativa, los uso para disfrutar audio de videojuegos, los tengo conectados con el cable de fibra óptica a un PS4 y la cálida del audio es increíble, los detalles en el sonido son increíbles. En cuanto al uso para música, el rango que tienen es increíble, en algunas canciones es como estar escuchando una canción totalmente nueva por la nitidez del sonido. En cuanto a los graves (algo que le preocupa a muchos) el sonido que da es muy bueno y si quieren aun más la opción de realce es excelente. La opción surround que da dos niveles es buena, pero a mi parecer sale sobrando con tan buena calidad del audio. Los audífonos los siento un poco pesados, sin llegar a ser incómodos y el aislamiento que dan es muy bueno, así que sonidos externos no los percibes.
