Sound that automatically adapts to your environment. SmartSound analyzes your sound environment and ensures that your individual audio settings with active noise cancellation (ANC) and HearThrough are automatically applied to deliver the desired sound quality. It filters out distracting background noises. The intelligent active noise cancellation (ANC) responds to your surroundings and activates when unwanted background noises are detected according to the settings made in the Sound+ app. The headphones feature eight microphones, four of which are used by the powerful digital ANC to filter out ambient sounds. With the Elite 85h, you can customize your music settings for a personalized sound experience and enjoy exceptionally clear sound quality with custom-made speakers. Thanks to up to 36 hours of battery life with a single quick charge (with ANC enabled), the Elite 85h will accompany you throughout the day without faltering. Advanced call technology uses six of the eight headphone microphones to further enhance voice quality and reduce wind and background noise. This results in crystal-clear sound quality that you can rely on during your calls, even in challenging conditions. With one-touch connectivity to Amazon Alexa, Siri, or Google Assistant, you can schedule appointments, search for local events, or have text messages read aloud using voice commands. Usable anywhere thanks to certified weather resistance. The Elite 85h is designed to withstand the elements. With its nano-coating of internal components combined with a 2-year warranty against water and dust, your headphones are literally equipped for anything that comes their way.
