Wired In-Ear Design

The Sennheiser CX 80S is a wired in-ear headphone with a 9.7 mm dynamic driver and a 3.5 mm angled connector. Weighing approximately 11 g, it is built for portable, lightweight listening. A 1.2 m cable connects the earphones to your device without batteries or pairing.

Fit and Connection Preference

The three included ear tip sizes (S, M, L) allow you to match the ear canal coupling for effective passive isolation. The inline smart remote handles calls and music playback directly on the cord. Buyers who want wireless freedom or active noise cancellation should look elsewhere.

9.7 mm Dynamic Driver

The single 9.7 mm dynamic driver delivers a frequency response of 17 to 20,000 Hz with total harmonic distortion below 0.5 %. At 28 ohms impedance, it is driven easily by smartphones and laptops. This driver specification determines the sound character and source compatibility.

Questions about this item

Does the 28-ohm impedance and 9.7 mm driver draw noticeable power from a phone during all-day listening?

The 28-ohm impedance is easy for any smartphone or laptop to drive, so battery drain stays minimal even after hours of use.

What source connector must my device already have for the angled 3.5 mm plug to work?

Your phone, tablet or computer needs a standard 3.5 mm headphone socket; the CX 80S has no wireless or USB-C option.

Will the 17–20,000 Hz response and 1.2 m cable integrate cleanly with an older portable DAC I still use?

Yes, the wide frequency range and standard 3.5 mm connection work with any legacy DAC or player that has a headphone output.
