You're on a train through an unfamiliar city and your headphones have you completely cut off — you almost miss your stop.
The OPN Sound Osso uses bone conduction to send audio through your cheekbones, leaving your ears fully open. You hear your music and your surroundings at the same time — announcements, station names, the person next to you. You stay present without giving up your audio.
Jump to specs ↓What it solves
Standard headphones create a tradeoff: audio or awareness. The Osso removes that tradeoff entirely. The bone conduction transducers sit just in front of your ears, so ambient sound passes through unobstructed. You stay alert to traffic, trail conditions, and the people around you — without pulling out an earbud every time something happens.
At 24 grams, it's light enough to forget you're wearing it over a full day of hiking or travel. The loop-over-ear design stays put during active movement without needing to be adjusted. IPX5 water resistance handles sweat and rain without issue, and USB-C charges it fully in 1.5 hours — the same cable as most modern devices. The built-in noise-cancelling mic handles calls clearly without reaching for your phone.
