Sennheiser CX Sport are absolutely tiny bluetooth earphones with secure fit ear fins, providing a great fit for men and women - ideal choice if you've had trouble with earphones being too large. (I fit size M tips and the CX Sport just disappears into my ears)
*digitaltrends.com: 8/10, Recommended. They charge rather quickly....the microphone was quite good... at eliminating background noise... offer clear, balanced sound no matter your music tastes.
CX Sport are sweat & splash resistant & very lightweight. New for 2018 and a nice combination of strong sound quality, secure fit and durable design and build.
