Open-Ear Bone Conduction Headphones

The OPN Sound Osso uses bone conduction technology to send mini vibrations through the cheekbones directly to the inner ear. Nothing sits inside or covers the ear canal, so the wearer hears audio while the ears stay open to ambient sound. The wireless design connects via Bluetooth for cable-free listening during any activity. Weighing only 24 grams, the frame loops over the ear for a secure and comfortable fit.

Suited for outdoor awareness.

Runners, cyclists and commuters who must hear traffic or announcements will benefit from the open-ear design. The IPX5 rating protects against sweat and rain during workouts. A noise-cancelling microphone keeps voice clear for calls on the move. Buyers who want passive noise isolation or immersive bass that blocks the outside world should look at a different style of headphone.

9-hour battery with two-hour charge

A single charge provides up to nine hours of continuous playback or talk time. Replenishing the battery takes roughly two hours. This runtime covers a full workday or a long training session without needing a top-up. Users who need multi-day power between charges will find the capacity limiting.

Questions about this item

Will the Bluetooth connection stay stable if I keep using my older phone?

The headphones use standard Bluetooth and are listed as universally compatible, so they pair with older phones that support Bluetooth audio.

How can I confirm the IPX5 rating is protecting the headphones during a sweaty run?

After exposure to sweat or rain, wipe the headphones dry; they are designed to resist water jets from any direction and continue working normally.

Does the package include a charging cable or do I need to buy one separately?

A USB charging cable is included in the box; no separate purchase is required for charging.
