Optimize your sound with the Sennheiser CX 300S earphones, which offer amazingly detailed sound reproduction and improved bass thanks to Sennheiser transducer technology.

The ear canal design reduces ambient noise to a minimum and the included ear adapters (XS, S, M, L) guarantee an individual fit in four sizes. The smart remote lets you control your music and answer calls. This product is the successor of the CX 3.00 with remote control.
