The Sennheiser CX 80U in-ear wired headphones deliver compact, wired personal audio for everyday use. Designed for compatibility with Android, iOS and Windows devices, these black earphones provide plug-and-play connectivity for calls and music through a single 3.5 mm connector. The lightweight housing and supplied silicone ear tips aim to provide a secure fit for commuting, remote meetings and media playback.

Advantages

How to use

Insert the 3.5 mm connector into the headphone jack of your Android, iOS or Windows device. Choose the silicone ear tip size that provides the best comfort and seal, then fit the earbuds into your ears with the cable hanging down.

Store the earphones in a pouch or case when not in use to protect the cable and earpieces.

Usage recommendations

For optimal sound and comfort, try each supplied ear tip size to find the best seal; a proper fit improves bass response and reduces outside noise. Avoid exposure to moisture and extreme temperatures and unplug the earphones by holding the plug rather than pulling the cable.
