Sennheiser CX True Wireless Bluetooth In-Ear Earbuds (Black)

The Sennheiser CX200TW1BLACK is a pair of true wireless in-ear earbuds that bring Sennheiser’s acclaimed sound into everyday listening. Powered by the German-engineered 7 mm TrueResponse transducers, these earbuds deliver clear mids, detailed highs, and a low end that can be pushed even further with the built-in Bass Boost EQ setting.

Thanks to support for AAC, aptX, and SBC Bluetooth codecs, the CX True Wireless streams high-quality audio from virtually any modern phone, tablet, or computer. The connection stays solid whether you are following a video on a laptop, taking a call from your phone, or stepping away from your desk to grab a coffee.

Comfort and isolation were a priority in the design. Each earbud is shaped to sit securely without pressure, and four sizes of silicone ear adapters help create a tight seal that blocks out much of the outside world through passive noise cancellation. This makes the CX True Wireless a natural companion for commuters, office workers, and anyone who wants to stay focused in a noisy environment.

With up to 27 hours of total playtime—9 hours on a single charge plus an additional 18 hours provided by the pocket-sized charging case—you can listen through a full workday and beyond. An IPX4 rating adds reassurance when light rain or an intense workout enters the picture.

Day-to-day control feels intuitive. A responsive touch surface on each earbud lets you adjust volume, skip tracks, answer calls, or summon your phone’s voice assistant without reaching for the device itself. If you want to fine-tune the sound or remap the touch commands, the free Sennheiser Smart Control App for iOS and Android puts those options at your fingertips.

Whether you value natural, balanced sound for critical listening or prefer a bass-forward profile for the gym, the CX200TW1BLACK adapts easily—and it does so in a discreet, reliable package that travels anywhere.
