Product Research

Features

Overview: The CX 310 are noise-isolating in ear canal headphones. They use dynamic drivers for a powerful, bass-driven stereo sound.

Sound Isolating Technology: The CX 310's in ear design works like an earplug to attenuate ambient noise. This enables you to listen at lower volumes even in loud environments.

Fit: Because every ear is different, the CX 310s come with three different size ear-tips to ensure a good fit. The soft flexible tips gently contour to the inside of your ear to create a comfortable secure fit, and won't fall out when you move.

Carrying Pouch: The CX 310s come with a carrying pouch for convenient handling and storage.
