The OPN Sound Osso is a true bone conduction headphone. Sound travels through your cheekbones to the inner ear, so your ear canal stays completely open — you hear the traffic, the trail and the person beside you while your audio plays. Runners on city routes, cyclists on gravel and anyone who needs an ear free for the room find these the most useful headphones they have owned, because they solve a real problem instead of just playing loud.
A flexible wraparound frame with a soft-touch finish makes the Osso disappear on your head. At 28 grams it sits at the light end of the bone conduction category, and the behind-the-ear loop holds through a long run without the slip-and-adjust routine you get with earbuds.
IPX5 water resistance shrugs off heavy sweat and rain — it is a splash rating, not a swimming rating, and we would rather say that up front. The battery runs 9 hours of playback and 160 hours on standby, and a full charge takes about 2 hours on the included cable. Bluetooth 5.2 holds the link to 30 feet (10 metres), and pairing is one tap on iPhone, Android, PC or Mac.
Bone conduction sport headphones, built for the road and the trail
As bone conduction sport headphones go, the Osso keeps the trade-off honest: your ears stay open, so you keep your situational awareness on a shared path, a road shoulder or a gym floor. One multifunction button covers play, pause, next track, previous track and volume, and the built-in mic answers and rejects calls and wakes your phone's voice assistant without you touching the phone.
