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 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.

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

There's no shortage of exercise-focused Bluetooth earphones on the market, but there's always room for one more if the price and sound quality are right. Sennheiser's CX Sport earphones are a bit on the expensive side, at $129.95, but they offer a balanced sound signature with some solid bass presence and sculpted highs. They also offer a lightweight, moisture-resistant design that pairs well with working out. There's really not much to complain about, although they don't do much to stand out from the competition. Design The CX Sport earphones have a thin, flat black neckband with neon yellow highlights on the earpieces and inline remote control. A built-in cable cinch makes it easy to adjust slack and achieve the ideal fit, and the inline remote is counterweighted with an inline plastic compartment near the left earpiece.
