Customer Ratings & Reviews

This earbud is great for someone who wants great sound of MW and more affordable price. This has good bass and sounds great on most genres. Charging case is not the smallest but good to carry around. Build quality is not the greatest but well built. Very easy to connect and customizable sound through the app.

My wife uses these to watch TV to. They were an upgrade from her old Beats Studio headphones, which were big and bulky They are nice to use and fall asleep with due to the convenient size. The quality of the sound is really nice when connected to the TV. They last for hours, but charge pretty quick.

I got these ear buds to use while working construction. I do a lot of sanding and these provide a welcome relief to constant buzzing. However they don't provide noise cancellation. They sound really good and my only complaint may be a personal issue. These do not stay in my ears. It's very frustrating how many times I've been up on a ladder and one of the ear buds falls out and lands below often in a bush or plant and I get to go down and find it. My boss isn't happy about that either as it's wasting time. I got these on sale for 99$ so I am happy with the performance to cost ratio.

I bought these when they were $199.99, but the cost has dropped a full $100 since then making these the absolute BEST sound I believe in it's class. This is premium sound for $99. For my taste of sound only, these are not far behind the B&O E8 earbuds and sound very on par with the Momentum 2 ear buds also by Sennheiser. Just a subtle difference making the B&O and Momentum 2 very slightly superior. The things I believe these lack, probably the reason for such a price drop, is no ANC (Active Noise Cancelling) and no auto pause if you take them out. However these do have touch controls that are even customizable. I do want to say that with this review, keep in mind that sound is always a personal preference. My taste in sound will not be yours. The verdict - If you are more concerned with sound quality over features, these are the earbuds for you. If you like decent sound but what more features, then you might look past these.

Sennheiser has always been one of those names associated with a good quality product, and these earbuds are no different! Right out of the box they look like your standard wireless earbuds. You might notice they are slightly larger. That's so they can house the larger driver in them. Being someone that loves a lot of good bass, these made me very happy! They are very easy to operate and get connected to the app. Pretty much all earbuds today are very similar. I think the main thing that sets these apart is the sound quality. Sure they aren't as small as some other pods or buds and such, but the little bit of a size increase amounts to a huge increase in sound quality. Ive tried tons of earbuds over the last couple years, some are very tinny, some are nothing but bass, and very few have a perfect balance of lows, mids, and highs. These are one of those earbuds. Using the companion apps EQ settings you can dial in the perfect sound for you. I like a good amount of punchy bass, but also for the highs and mids to be equally represented and not drowned out. I was very easily able to achieve that with these earbuds. I found these quite comfortable in my ears with the silicone tips that came on them, but they also include a couple other sizes if you have smaller or larger ears. I wouldn't recommend these for any activities where your head is bouncing around alot like jogging or something like that. I could see them possibly falling out of your ears. Also, they aren't IPS rated so you dont want to get them wet or too sweaty as it could cause problems. But for just chilling and relaxing or walking around town these would be perfect. They aren't noise cancelling, but they do give a pretty good seal around your ear to block out a lot of outside noise. One complaint with these (and many other earbuds ive tried) is the touch controls. They never really work the way you want them too and I wish companies would stop trying to integrate them into these kinds of earbuds. I can see tapping on the right ear to increase volume and the left to decrease but thats really all you need. Anything else can be controlled with the phone. Often times you end up tapping the wrong pattern and then you have to try and figure out what you did. Or you just adjust them in your ear and accidentally activate something. Overall, these are a very solid and great sounding and have great battery life. I've been using them all week and I have yet to plug them into the wall.

Received these earbuds fully charged right out of the box. They paired quickly and easily via bluetooth and I downloaded the Sennheiser Smart Control app to customize the earbuds before taking them for a spin. The app allows you to adjust the EQ to your liking and customize the tap controls for each bud. The app is very simple and easy to use which is always appreciated. I was BLOWN AWAY by the sound quality when I started listening to music. These have deep bass and are clear on mids and highs. They also get loud and, although they don't have noise cancelling, they fit snuggly in the ear and block out most outside noise. Not necessarily a bad thing because it's good to be able to hear cars approaching, ambulances, trains, etc if you're wearing these walking around town. Overall, I am completely impressed with the sound quality vs other wireless earbuds I've owned in a similar price point. Touch controls and gestures are easy to use due to the size of the earbuds and with how much they stick out. So if you're looking for a discreet, sleek look, this isn't it. They are blocky looking, but that's a style choice. Personally, I don't have an issue with the way the design because the slightly larger size gives them great sound and makes the controls easy to use. They also fit comfortably and didn't feel heavy or like they were going to fall out. Call quality is good and the person on the other end was able to hear me clearly, even with some outdoor ambient noise that the microphone did a good job blocking out. The only reason I deducted a star was because there is no water resistance, meaning no sweat resistance. Granted, Sennheiser had to make some compromises to get the price $100 lower than their other earbuds and keep the same sound. But this is one feature that I think every wireless earbud should always have. If you plan on using these for working out or doing yard work, you'll probably need to look for something else. However, if you're looking for something for the office, walking around town, travel or any situation that will avoid sweat, water or rain, these sound incredible and are easy to use with an intuitive companion app. I highly recommend them for those reasons. If they had water resistance, they'd be 5 stars all the way.

These are EXCELLENT. very professional quality sound. For a basic strip down version of the momentum 2's, they pack the same sound. Great app to use and EQ and customize your sound. Everything else pretty standard and basic.

I love these headphones. My first Sennheiser headphones and these have high quality. They sound great and fit perfectly. I got these when they were on sale and I got them for a really good deal. Recommend to anyone!

No idea what I was expecting but I feel these could be better out of the box. Made better with EQ on listening device.

I will say before I write my review that these were good earbuds. The sound was nice, but everything else was something I had to work around so they could be a good fit. The different earbuds didn’t fit my ear no matter what position I put them to( which I understand is just my ears fault for being shaped the way they are). I got these back in February of 2021 and they served me pretty good for the time being, but today I tried to pause a song and then my whole right ear bud loses sound. No more sound outta that side. So now I have to have the right ear bud just free Willy in my pocket cause when I try using the left ear bud while the right is charging, it won’t work. I paid $115 for something that had multiple connection problems which I thought I could figure out so I stayed optimistic. Then today I lose all sound in the right ear bud. I would get these again because of all the problems I had trying to get these to work properly but the sound quality was good, I will say that.

Sound is great. Controls are a little sensitive and the battery life is weaker than I’d like.

I’ve had these earbuds for about 5 months now. I love them for the following reasons: sound, convenience of use, easily charged and charge last for many hours. I definitely recommend them.

These headphones fit into my ears nicely. Also the sound is fine for me. What I do not like is the connectivity. I like when I turn on a pr of headphones, it locates my phone and begins to play. These are not that way. Another issue I have is that I had to download amp app to use them with my iPad. I would not recommend these headphones for purchase.

Good sound not that bad. I just wished it was a lil louder. Battery does last long. Sounds a bit more clearer than air pods but air pods has that more thick bassy sound.

Sounded great, fits nice in my year! But can’t use one at a time!!! So I returned it.

It works and sound wonderful for music with fast beat. The bass is a strong and clear. Highly recommended for music listeners on the go. Thank you Bestbuy for fast shipping and good price!

Sennheiser - CX 400BT True Wireless Earbud Headphones - Black

Great sound at a great price works just fine Light weight n easy to use

This is not worth the price. I was excited to use this. I own Jabra 75t and Bose noise cancellation wireless headphones. I thought these would be better. My Bose suck. The Jabra’s are great sound wise but they fall out my ear way too often. The Sennheiser was perfect in the sense of fitting in my ear I did have to change to the small ear adapters. Sound was very minimal. I’m a treble and bass person. If you don’t care for this you’ll love them. But Treble and Bass matter for me. Sennheiser failed big time in this department. I even played with the equalizer in the app provided. Also volume was very minimal. No noise cancellation. I was one the train in NYC and could barely hear my music. Also it’s very touch sensitive. My calls kept hanging up because my hair would brush up on the right earbud. Super annoying constantly apologizing to people for this. It’s definitely a no for me. Returned! I forgot to mention battery life is fair. Not bad lasted for about 5hrs. Comes is a C-usb. Back to the drawing board to find great wireless headphones

Sound quality is better than air pods. They fit pretty good so they don’t fall out. definitely worth it especially when they’re on sale.
