Sennheiser incorporated various technologies to deliver clear and accurate sound reproduction through Sennheiser's 7mm TrueResponse drivers. With support for Bluetooth 5.2 and the aptX Adaptive codec from compatible source devices, you can hear every detail in your music and customize it with your choice of preset. When listening, outside noise can't interfere thanks to adaptive noise cancellation that automatically adjusts based on your environment. Even your voice is prioritized for purity with high-quality voice pick-up using three beamforming mics in each earbud. Transparency Mode When you need to talk to friend or order a drink, you can tap the MOMENTUM True Wireless 3 earphones to engage Transparency Mode, which temporarily stops noise cancellation to let the world back in. Wireless Charging Case On a full charge, these in-ear headphones can run for up to 7 hours, with an additional 21 hours of power available within the included charging case. When it comes time to charge the case itself, you have a choice of using a USB Type-C cable or an optional Qi-compatible wireless charging pad. A short USB Type-C cable is included. Quick Charge In a rush A quick 10-minute charge in the case can give these earphones up to 1 hour of playback time. Splash Resistant You can use these MOMENTUM true wireless earphones while working out, thanks to their IPX4-rated splash resistance.
