Calling all audiophiles! The Sennheiser CX 400BT True Wireless Earbuds have arrived on the scene. Providing a perfect fit in the ear, these minimalist earbuds use 7mm bespoke dynamic drivers to deliver optimal audio playback over the course of their 20-hour battery life. A built-in equalizer and customizable touch controls make them perfect for everything from enjoying music to taking calls and flipping through playlists with ease.
Each pair of the Sennheiser CX 400BT True Wireless earbuds comes with four different silicone ear adapter sets in extra-small, small, medium, and large sizes. Also included is a compact charging case and USB-C cable to add extra juice. The CX 400BT features many of the same notable features of the Sennheiser MOMENTUM True Wireless and rivals their performance, albeit in a more compact form.
