Open-ear bone conduction headphones

OPN Sound Mezzo+ rests outside the ears and transmits sound through cheekbone vibrations to the inner ear. The open-ear design keeps the ear canal free, allowing the wearer to hear music and calls while staying aware of surroundings. An ergonomic over-ear loop holds the headset securely during movement.

Bluetooth 5.3 wireless connectivity

The headphones pair via Bluetooth 5.3 for a stable link with phones, tablets and computers. Universal compatibility means no proprietary dongle or app is required. A two-hour charge fills the battery, and a ten-minute top-up restores five hours of playback.

IPX6 water resistance for active use

Rated IPX6, the set withstands heavy rain and sweat without damage. Environmental noise-cancelling microphones filter background sound for clearer voice calls. The lightweight frame leaves the ears completely unobstructed, making it unsuitable for listeners who want passive noise isolation or in-ear seal.
