The headset

The product

Open-ear bone conduction rated 0–110°C, IP68 to 2 metres, 32GB onboard. The canal stays empty. The phone stays in the locker.

Matte charcoal, the hero.

    Why it exists

    The last four minutes

    The hardest part of every sauna and every plunge. Not the heat. Not the cold. The counting.

    So we built something that doesn’t mind

    1. 10 hrs

      You get out early. Not because it is too hot — because it is too boring.

      Playback

      Long enough that you stop counting.

    2. 32 GB

      A 90°C room is no place for a phone, and you bring it anyway.

      Onboard

      Load it at home. Walk in empty-handed.

    3. IP68

      Bluetooth does not travel through water.

      2 metres

      Offline MP3 below the surface.

    4. 0–110°

      Silicone softens, slips and dies in sauna heat.

      Heat-stable frame

      Heat-stable pads. The frame remembers its shape.

    5. Buttons

      Numb fingers and touch controls do not get along.

      Magnetic charge

      Physical clicks. No port to corrode.

    Anatomy

    What’s
    in it

    Open-ear bone conduction, sealed for the two worst rooms in the building.

    1 2 3 4 5 6

    1 Heat-stable frame

    Won’t warp, soften or go tacky in heat.

    2 Heat-stable pads

    A heat-stable compound, not standard silicone.

    3 Bone conduction

    Sits just in front of the ear. Nothing goes in the canal. The science

    4 Physical buttons

    Sized for numb fingers and wet hands. No touch surfaces.

    5 Sealed housing

    IP68 to 2m. 32GB onboard, Bluetooth 5.4.

    6 Magnetic charging

    No port to corrode. Ten minutes gives three hours.
