good design with a large selection of accessories to fit all and quickly charges but holds it charge well

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.]

The bass is phenomenal and the general sound quality is great aswell. Just as anyone should expect from a great brand like seinheiser. Fit great in the ear too.

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...

The beads are too soft so they do not hold the construction in place. On the other hand, the handsets are just as neat as they are of pure suction power. It is possible to remove the useless beads and put in the recycling for plastic.

Thanks to the inclusion of the Ear Fins, the Sennheiser CX Sport sits extremely well and securely in the ear, while delivering clear and rich sound with no annoying after-effects. This is an excellent feature that will certainly go down well with those looking for the best in mobile use.

Wish I'd spent more time researching these. The buds come out straight away regardless of what attachment is used and so are totally useless. Even when sat down the sound is awful. Just thrown my money in the bin.
