Review: The sound is beautiful and full - I love the sound of these. The sound is wonderfully warm. Engaging, surrounding and coaxing, and the bass is excellent. Audio superlatives aside the next best thing I like about these buds are the fit. They're extremely comfortable, in my opinion only the Technic AZs better them, with the prior Sony C500/C700 models matching them. Both the Sonys and Technics are smaller and lighter, but these Sennheisers have a better in ear seal than both. Battery life seems good, ive never systematically tested them but ive also never exceeded their capacity in use. The ANC is decent, it works to a degree, it makes a difference. The sound profiles, including bass boost definitely have an effect, and the transparent hear through feature is very effective. Great for needing to keep an eye (ear) out on other things as listen while going about your daily basis. Bought these alongside multiple other pairs to compare and their combination of warmth, bass, comfort and great value for the price was unbeatable. Thoroughly recommend.
Review: Great sounding for the price - These earphones sound great. They're my first set of true wireless earbuds so I was afraid of them falling out of my ears or getting lost, but they've so far stayed in my ears just fine. In the box you get a usb-c to usb-a charge cable, manuals, some replacement ear tips in different sizes, and the buds themselves with their charging case. First impressions were that the case felt robust and there was a good magnetic grab that stops the earbuds from falling out. I dropped the case by accident and it protected the buds perfectly without them flying out. The battery life is great, I tend to use the buds for 3-4 hours at a time, but after around 6 hours they do run out of power depending on the volume they're set at. The charge up again quickly when they're put back in the case, so this isn't ever really an issue. They are comfortable to wear, but after a few hours I did find that my ears got a little sore. I think this is pretty normal though! The noise cancelling is pretty good, but I really like the transparent mode - this allows you to instantly pause your music and use the anc microphone to hear what's going on outside to maintain a conversation - really useful in a shop when you reach the till. My only gripe is the touch controls - they're okay... they're a bit fiddly, you get audible feedback when you input commands, but they're very quiet and it's easy to miss so i often find that i skip tracks by accident instead of pausing them. Finally, the sounds quality. It absolutely slaps. For headphones at this price point, I'd expect them to be decent, but there isn't really any issue with bluetooth compression. The sound stage is wide and base and mid frequency response is good. The only drawback is that the low end gets a bit muddy when listening to fast metal, but this is really easy to clean up using the partner app you can download on your phone. The eq settings are easy to tweak to your liking and this makes them my favourite headphones by far.

## Questions & Answers

**Q: I've read in a few places these earbuds are big and bulky. Are they much bigger than other brands, and are they comfy and stay secure in your ears?**
A: Hi, they are quite small in comparison with other brands, I've had Jlab and they were bigger, I saw Bose and they are much bigger. I have small ears and they are ok. They sit well in my ear as I exercise in them, obviously you need to correct position sometimes. I cannot compare them with airpods as I never had them. I'm very happy with my earbuds.

**Q: Noise cancelling automatically switches off if I make a call, resulting in hearing loud external noise on phone calls- is this defect or design flaw?**
A: I haven't got a pair, but i'm looking to buy, this may be a feature called sidetone. This is where your microphone is played back through the speakers during calls to give you an idea of how loudly to talk for the other end of the conversation to hear. If you left full noise cancelling on and you couldn't hear your own voice, you;d end up shouting down the phone. I just googled "sennheiser cx plus true wireless sidetone" and the second result is a review describing the ability to adjust the sidetone in the sennheiser app. Good Luck.

**Q: I'm totally new to these (& not good with technology) - are they just to use with a smartphone, or can you use them with a Chromebook, for example?**
A: They are easily used with a phone, tablet and laptop by pairing them with each device as you choose. I've found them very easy to pair to any of my devices. 😀

**Q: Do these sync ok with ipods?**
A: Yes, no problem.

### ⭐ Dead After a year - avoid
*by A***. on 14 March 2023*

New Review: Now basically useless - a year of sitting on a desk and using for work / casual gaming. The battery now holds a whopping "one hour" of charge. I'd expected to get a couple of years consistent use out of them - but the batteries are obviously below par and don't hold the full charge like they used to. Avoid them. Old Review: Are you a PC user, with glasses, wanting wireless, good quality buds? You found them. I wear glasses, for years I've just 'put up' with headsets and non-stop moving the headset/adjusting my glasses. I'd occasionally get headaches etc from doing this. No matter the prescription, no matter how much I paid for padded headsets etc etc. These sound amazing - ofcourse my top end headsets out perform them - but for day to day listening for long periods, these are great. I use them whilst coding, listening to some high quality sound scapes and these things pick up the tiniest detail. I also use them when gaming - and I've noticed next to no latency at all. Something I was extremely worried about with a bluetooth solution. They are amazing for gaming too. My headaches are gone, my focus is improved - and they sound amazing, big overall win for me. Things I like most: - Automatically connecting / disconnecting from audio when taking out / placing in the case. - Removing an earbud/tapping one on the side, stops media from playing. AMAZINGLY useful in an office environment when people tap you on the shoulder etc. - Charge / battery life. I keep these in all day - but the battety has yet to die in use, that's because when I nip to the loo or make a brew - they go in their case and fast charge. Unless you intended to sit in one spot for a solid 8 hours, I doubt battery life will be an issue for you. - Sound, obviously, I think these tick all my boxes. Minor cons - The ear tips just aren't that comfortable. You have three sizes to pick from, and after using them for two or three hours you'll want to take them out to give your ears a five minute break.
