Sennheiser CX True Wireless In-Ear Headphones - White is rated 3.0 out of 5 by 5.
Rated 2 out of 5 by from Not as good as thought I´ve had the "luck" of trying this product throught reviewclub and i though they where better then they where. These ear-buds where not my favorite, great sound but no ergonomic or comfortable, could not get them to fit my ears with any of the buds that came along in the package. And when trying to put them in the ear they slides out and you accidently pushed the touch-button on the bud. I tried to get them sorted for many hours and a couple of days, but no. I would actually not recommend these because of this issue. I rather have these with better ear-forms and no touch on the outside, then I think these would be awesome to have when working out and walking. • Not ergonomic • To easy to push the touch buttons

Rated 3 out of 5 by from Was expecting more! When i first tried the headphones i was very disappointed. They had a muddy sound, regardless of what music i tried. Not at all what i was expecting from a brand like Sennheiser. I downloaded the smart control app, and it was a hassle to get it to recognize the headphones. After a firmware update and an update to the app it now seams to work fine. The app has a built in equalizer which is just awful, unless you switch it to be a graphic eq, you move a dot around and have almost zero control. After switching the eq to a graphic look it's now somewhat useable. Using the eq I could get the headphones to sound decent, -1 dB to mids and +2 dB to highs. The headphones are a bit heavy and when i walk it feels like they are going to fall out. They also don't isolate from outside noise to well. The touch controls are good and intuitive. Battery life is also good. If you can pick them up at a reduced price go for it, otherwise it's a hard pass.

Rated 3 out of 5 by from Average headphones I have had these for about a month. I don’t like them that much. The design is a bit weird compared to other wireless ones that I have tried. I miss a “wing” that holds the headphones in place. The sound is ok with an ok bass. Battery life is perfect. One can listen to music and podcasts all day long without draining the battery.

Rated 3 out of 5 by from You can get better Battery life excellent. Touch buttons annoying. Left earphone fazed out so got money back after 6 months. Sennheiser offer a 24 month warranty. The microphone is not worth using, it is super quiet. There is a trick to securing these tightly - dont just shove in the ear.

Rated 4 out of 5 by from Nice battery time I have been testing these for a few weeks now, and I´m impressed by battery time, sound quality (thanks to the adjustable features in the app), and connectivity.
