[EXTENDED PLAYTIME] Each pair of headphones can last up to 20 hours on a single charge, and the included transmitter doubles as a hassle-free charging dock that’ll fully charge your headphones within 1.5 hours. [CLEAR VOICE MODE] By lowering background noise and boosting voices, the Duet’s clear voice mode allows you to hear on-screen conversations and dialogue more easily. [PASS-THROUGH SUPPORT] The Duet’s pass-through capabilities allow you to listen through both an external speaker and the Duet headphones simultaneously. [INDEPENDENT VOLUME CONTROL] Both headphones have significantly higher max volume levels than competitors’, and each pair of headphones comes with built-in, independent volume controls, so you can adjust your own volume without affecting the other’s. [WATCH IN PEACE] The Duet comes with 2 pairs of wireless headphones that are pre-paired with the transmitter / charging base. Listen alone or with a partner at your own desired volumes.
