Sennheiser CX 80S

The Sennheiser CX 80S are wired in-ear earphones with a balanced, natural sound free of exaggerated bass or treble. The inline remote with microphone handles calls and music playback, and silicone ear tips in three sizes give a comfortable fit and good isolation from ambient noise. The earphones weigh 10 g and connect via an angled 3.5 mm jack plug.

Balanced, natural sound

The closed dynamic transducer covers 17–20,000 Hz without unwanted extremes in either the highs or the lows. Total harmonic distortion stays below 0.5 %, so music sounds natural and stays easy on the ears during long listening.

Inline remote with microphone

The inline remote has a button for taking calls and controlling music playback. Its omnidirectional microphone, with a 100–10,000 Hz response and −42 dBV sensitivity, carries your voice on calls.

Ear tips in three sizes

Silicone ear tips in three sizes make it easy to find the right fit in the ear canal. A well-sealed earphone sits comfortably and shuts out ambient noise.

Light enough for every day

The earphones weigh just 10 g and their compact shape fits any pocket — for the commute, a walk or the gym.

Closed, ear-canal design

The earphones sit in the ear canal and the closed design dampens ambient noise, so there is no need to turn the music up unnecessarily.

Up to 119 dB SPL

With an impedance of 28 Ω the earphones work well with a phone, laptop or player and reach a sound pressure level of 119 dB SPL.

Angled 3.5 mm jack plug

The 3.5 mm jack plug is angled at 90°, so it does not stick out of a phone in your pocket and the cable is under less strain at the plug. The earphones connect to any device with a 3.5 mm headphone output.

Symmetric 1.2 m cable

The cable is 1.2 m long and both branches to the earphones are the same length. The inline remote with microphone hangs below your chin, where it picks up your voice on calls and is within reach when you want to take a call or pause the music.
