Osso pairs bone conduction audio with an open-ear design, sending sound through your cheekbones to the inner ear and leaving your ear canals completely clear. That makes it a natural fit for runners, cyclists and commuters who need to hear traffic, trail partners or platform announcements while they listen. The flexible wraparound band sits behind the head and the whole headphone weighs just 24 g, so it stays put and stays comfortable through long sessions — with nothing pressed into the ear, there is no soreness after hours of wear. IPX5 water resistance handles heavy sweat and rain, Bluetooth 5.2 gives a stable 33-foot range, and the 9-hour battery recharges in about 90 minutes.
