Product details
The CX Plus True Wireless exceeds all sound expectations with noise cancelling, effortless smart controls, and a sleek design for maximum comfort. The independent use of the earbuds allows for the left and right earbuds to be used individually or as a pair. The dynamic 7mm TrueResponse transducers, produced in Germany, deliver Sennheiser's signature sound quality. With a playback time of 8 hours and a total battery life of up to 24 hours via the charging case, the CX True Wireless offers an all-day audio experience – in any environment, thanks to passive noise cancellation and an ergonomic design for a secure fit in the ear. The Bass Boost feature allows for more intense bass, which can be activated with a special EQ preset through the Smart Control app.
