I bought these a few weeks ago on advice of salesman in store after advising they were needed for running. These headphones are not fit for purpose, they fall out easily (despite trying all supplied buds and fins) and part of the problem is the control/battery pack below each ear which seems to...

These earbuds are perfect for running and no doubt other sports too! They sound great as you'd expect from Sennheiser, and work well - I didn't have any connectivity issues with my Android device at all. Would recommend! [This review was collected as part of a promotion.]

I purchased these headphones to use while running and working out. I'm a big Sennheiser fan, and the sound did not disappoint. The headphones were fairly comfortable, and seemed like a decent fit for regular wear.

Great sound; Comfortable, decent fit for non-athletic use

Bad fit for athletic use; especially running

A solid-sounding and appealing pair of wireless in-ears - we wouldn't hesitate sipping them into our gym bag We wouldn't classify the CX Sports as a Sennheiser personal best, but they're still a solid and appealing pair of Bluetooth headphones.

Clear and detailed sound; Punchy; powerful delivery; Full-bodied bass

Rivals more rythmically adept

The Sennheiser CX Sport wireless earbuds are a fantastic pair of sports headphones, thanks to bassy audio and a comfortable fit – but there are cheaper options out there.

Fantastic audio quality; Sports-friendly design; Comfortable to wear

Not the cheapest option; Mids could be richer

While I like different genres of games such as first person shooters, role-playing, platformers, racing, and more, I have recently been enjoying more multiplayer games. Whether it is the hot kitchen of Overcooked, the space traveling of Lovers in a Dangerous Spacetime, or casual party games from...

Sennheiser's CX line of in-ear headphones have been around for years, and that legacy can be seen in the Sennheiser CX Sport. These wireless headphones bare similarities to the Sennheiser CX 6.00BT – but, as you'd expect, have been built to survive sweat and to not fall out of your ears during a...

Secure fit; Overall good sound quality; Storage pouch and accessories; Robust built quality

Lack of isolation may be problematic; Slightly long and awkward cable; Relatively short battery life; Bit expensive

I really hoped things turned out well with these headphones. In regards to sound quality for a pair of in-ear Bluetooth headphones, the sound is amazing. Probably the best sounding sports headphones I've ever owned and I've owned Bose Soundsport Wireless and Powerbeats 3.

This is the second offering from Sennheiser that I have seen in the ‘sports earbuds' category. Being wireless means that it matters not how much vigorous exercise you do as the only connection is between the two buds whatever position the rest of your body contorts to the earbuds stay firmly rooted...
