Everyday wireless earbuds for commuters

The Sennheiser CX True Wireless delivers signature sound through 7mm dynamic drivers in a compact white in-ear design. Passive noise cancellation and four ear adapter sizes create a secure fit that blocks outside noise. Intuitive touch controls handle music, calls and voice assistant without reaching for a phone.

Bundled adapters and EQ let you tune fit and bass

Four silicone ear adapter sizes ship in the box so you can match the seal to your ear canal for better isolation and comfort. The companion app adds a built-in equaliser and Bass Boost preset, letting you adjust the tonal balance without extra software purchases.

Open the case, pair, and tap to control

Initial pairing starts automatically when the case lid opens, then touch panels on each bud manage playback, volume, calls and voice assistant. IPX4 splash resistance survives light rain and sweat, though the buds are not rated for submersion or high-pressure water.

Questions about this item

How long will the internal batteries last before they need replacing?

The earbuds give up to 9 hours of playback per charge and the case adds 18 hours on the go, totalling 27 hours before you need to plug in.

What limits continuous listening time the most?

The earbud battery capacity caps each session at 9 hours; after that you must return them to the case for a recharge.

Do the earbuds get hot or noisy during all-day use?

They run silently and stay cool because there are no fans or active electronics that generate noticeable heat.
