NENRENT S570 Bluetooth Earbud,Smallest Mini Invisible Wireless Bluetooth Earpiece Headset Headphone Earphone with Mic Hands-Free Calls for iPhone Samsung Galaxy LG and Smartphones Rose Gold (1 Piece)

This is the first time that I have ever ordered or even used a Bluetooth earphone, so I wasn't really sure what to expect in terms of sound quality, battery life, and wearing comfort. Well, this is one of those few times when all those aspects, plus some others, exceeded expectations. First, I'm really happy with the sound quality, with sound every bit as good what I would get with any similarly sized wired mono earphone. I bought this primarily to listen to spoken word podcasts, so the fact that I'm listening only in mono is not a negative because I wanted to keep my other ear open to be able to hear around me anyway. I'm also really surprised by how long battery life is, which easily outlasts over five hours at just over half volume level daily. In fact, I haven't yet been able to see whether it really lasts the six hours stated as its approximate run time because I just don't normally listen to podcasts quite that long at a time. Wearing comfort is also at least as good as with wired earbud type earphones, and there is the option to wear this either with or without the silicone ear cushion depending on your preference. I normally wear this while walking a considerable amount, so I put the ear cushion on to help keep the phone in place to prevent dropping it, a very real concern if not really kept secure in the ear opening. As a suggestion, the earbud is intended to be worn with the pushbutton switch upwards instead of down -- something that I missed going through the photos here on Amazon -- and I made the mistake of wearing it wrong, making it a bit awkward and hard to listen to until I recognized my mistake in wearing them with the switch down. Putting the switch up immediately made this much more comfortable and easier to hear. Also, it's worth mention that every person's ear shape differs, so you it's worth the time to adjust the earphone to get a proper seal and comfortable fit, and you really want to be sure to keep it in properly or it can fall out and either get destroyed hitting a hard surface or lost, tiny as it is. I'm sure there will be some people who confuse this earbud with the type of earbud equipped with a microphone to use to take phone calls, so let's make it clear that this is for listening only. As a minor downside, the instructions are written in poorly translated English, but it wasn't hard to figure out how to use these the first time. There is only the one button to control this, so I'll explain the three ways that the button is used: 1) With the earphone off, hold in the button for three seconds until the (female) voice starts to say "Power On," then immediately release the button. This is of course a toggle, so holding it in for three seconds while already on powers down the earphone. 2) In order to pair the earphone with a transmitting Bluetooth device, start with the earphone powered down, activate pairing mode from the transmitting device, quickly hold in the button on the earphone for five seconds straight, extending the button press beyond the spoken "Power On." Immediately after the spoken "Power On," it will now flash blue and say "Pairing." I use this primarily with a Sandisk Clip Plus that identifies it as a Nenrent device on screen, so watch how your own transmitting device recognizes the device, then be sure to have the transmitting device add it to its list of trusted devices, and you're ready to go. 3) If you're listening with the earphone and wanting to pause rather than fully power down, simply click the switch once and the audio instantly pauses, requiring only another click to start playing again. As a small consideration, there is a tiny bit of latency (lag or delay) with transmission using my Sandisk Clip Plus and laptop, something that I believe is inherent to the transmitting device rather than the earphone itself, as there is at least one review on Amazon from someone who states that he had no latency while using the earphone to watch movies, an application that would make any latency most annoying. This isn't really a concern for me, but it's worth mentioning for those who may at first fault the earphone. The earphone can work its way out if you bounce around a lot, at least for me with my rather narrow ear opening, so it's probably a good idea for the average user to occasionally check and readjust should the earphone start to work its way out while exercising or otherwise doing activity that could shake it loose. I've already had that happen once, with the earphone landing on a tile floor, but thankfully the earphone didn't get damaged, probably because it's so well constructed (polycarbonate?) and light, but nothing is invincible, and something so tiny is easily lost. The charging cable this comes with is a USB cable with a conventional USB-A connector (plugs into any computer USB jack) on one end and a tiny connector on the other end to insert into the earphone jack, and a blue LED comes on when charging; and you'll know it's fully charged when the LED goes out after a little over one hour or less depending on how far the battery is depleted when first plugged in for charging. It also comes with two ear cushions, so it's nice to have one extra. The charging cable is specific to this earphone, so it's nice that, at least currently, Amazon (Prime!) has a reasonably priced package sold by Nenrent that includes a cable and two ear cushions for those who may damage or lose either of these items. To be helpful, here's the current direct link to that - Set Eartips and USB Charging Cable for NENRENT S570 Bluetooth Earbuds I'm really happy with how the earphone performs, but what really tips the balance for my review from good to great is that it comes with a really nice zippered semi-rigid case that leaves plenty of room (but not too much) to accommodate the earphone, the charging cable, the spare ear cushion, and my Sandisk Clip Plus, which is a fairly large (2.60 x 1.74 x 0.68 in.) Bluetooth capable MP3 player, almost as if the case had been custom made to store and protect all of these pieces. In fact, there's even enough room to the side of where player sits to allow at least two more (if I wanted to put them there) identical earphones or probably (with a bit of judicious wire placement) a single wired earphone in addition to the Bluetooth earphone. The case is just over half the size of my Samsung flip phone, fitting easily in the palm of my hand, and even includes a carabiner-type clip to easily snap onto a belt loop to easily carry without fear of dropping it. It's really nice to be able to keep all of these items together in a small case that protects them from drops or minor water splashes or rain, so A+ to Nenrent for having the forethought to include a case that keeps it all together. I like this so much that I've already decided to buy a second one as a spare should I ever get careless and lose it. Well done!

Five stars doesn't even come close. It's hard to know where to start. I have tiny little ears - they are smaller than my 5YO's - and ear buds always hurt. This thing is so comfortable - it never comes loose and it never hurts. I've bought a lot of wireless headphones over the years, and they always skip or crackle or cut out. This thing sounds great, even when I'm dancing around my kitchen doing the dishes. It's a little tinny, I guess, but you aren't going to get kickin' bass for $20. And I haven't had any problems with phone calls - there is clarity on both ends. It just works. You don't have to fight with it to get it to pair - you turn it on, and it pairs. I have long fought with how to keep my phone on my person while I'm at the office. So many women's garments have no pockets. Even if they do have pockets, they tend to be tight, and the phone looks bulky. The beauty of the NENRENT is that now I can put my phone in places that are pretty inaccessible (like under my dress up the legs of my spanx or down my back in a case clipped to my camisole) and still catch my phone calls. Reaching up your dress to grab your phone during a business meeting is not a good thing. :) I don't wear it when I'm not actively using it. Because of my tiny ears, it is not as discreet for me as it looks in the picture. It sticks out pretty far for me. But, it's a lot more discreet than those dorky ear clip things. It also REALLY blocks your hearing in the ear that you're wearing it in. When I'm not using it, I tuck it into my bra - it stays put perfectly. Easy peasy. The listing says that it will last 5 - 6 hours with continuous music playing. I've never tested this. However, I can tell that leaving it on all day and using it occasionally, such as taking a phone call here and there, asking Siri to read my notifications when I'm running between meetings, and listening to a little music for an hour or so in the evening, it lasts from morning until night without losing ANY battery. The battery is still fully charged at the end of the day. It's simple and intuitive. There aren't a hundred button sequences that you have to remember. It's tiny, so you get on, off, pause, answer phone call and decline phone call. It talks to you when turn it off and on, so you know when it's on, off and connected. When you receive a call, it announces the number, but it does it pretty slowly so I usually don't wait for that. I guess my only complaint - and the opposite would be so much worse - is that it is loud. When I'm listening to music, I turn my phone down to the last click on the volume setting (any further down would be mute), and it's pretty loud right in my ear. But, that means you can hear, so I'll take it. I don't understand how I bought this thing for $20. Very nice product, especially considering the price.

I bought this exactly 1 year ago to the day and I love it. I use it to chat on the phone while housecleaning or to listen to music while I walk. It pairs up very quickly and easily and it has never run out of power for me. I usually charge it after each use so it's ready for the next time. I have very small ear canals and this fits perfectly and is very comfortable, without the added slicone extra. There are only three things that keep this review from being 5 star. People have told me that outside sounds are pretty loud (so noise cancellation isn't great) and when I walk, if I carry my phone in my hand, it cuts in and out. If I wear it in my phone belt it works fine. Not sure why that is ever an issue as I can walk pretty far away from my phone without losing a signal if I set it down in the house. The last thing is that it will get slippery and fall out when exercising. That might not be an issue if I could use the silicone extra or if, as one reviewer said, it had a silicone overlay which I thought was a great fix for that problem. Overall, I would buy another and it's actually less expensive than when I bought it last year by a few bucks! Really great product!

Okay, gotta be honest. I bought these because I wanted to sneak in headphones so people wouldnt notice. It totally worked. I was very impressed with the sound that came out of these. Only issue is that the plastic covering that goes in your ear can become a bit loose, that if you put it in your pocket that will usually come off, but once it is in your ear it is alright. I would not use this for sports though because it will fall out.

I've had another of these for years but had to replace it, the sound quality was terrible this time around, constant faint buzzing in the background. UPDATE (June 5th, 2020): The support center reached out to me after I left this review and has offered to send another at no charge! They have been so helpful and all their products have a 1 year guarantee. I will give it a try and hopefully it's the same high quality I remember from my first purchase years ago. They fit so well in my ear, better than the replacements I got, so hopefully! I'll update again when I try it out! UPDATE (June 11th, 2020): I have received my replacement ear bud and it's just as good or better sound quality than I remember my first purchase being. And this ear bud truly does fit better than any ear bud, it's like it disappears in your ear, unnoticeable and I can sleep with it in when I'm listening to something my partner doesn't want to listen to. I highly recommend this product, and especially the support team, they are terrific!

es comodo, funcionaban muy bien hasta que han pasado 4 meses y sin motivo aparente han dejado de funcionar.

Wow, what a great product. It came very fast. It is very easy to pair it with any blue tooth compatible device. The battery life is pretty good, it got a USB connector for charging. It is very useful for me since I got a 1-year-old kid she always pulls if I use earphone or headphones, but with this,, she won't be able to see I am using earbud. I use this a lot during the daytime, and I don't feel uncomfortable wearing this. Great product.

For the price, no complaints, does the job well enough.
