Why audio

Four headaches

The rooms are the easy part. The minutes are not.

  1. Heat Steam beading on skin in a hot room 35–110°C

    Ruined everyday earbuds

    AirPods are rated to 35°C. A sauna is not.
  2. Sauna Sweat running on skin on a sauna bench 15–20 min

    Boredom ends sessions

    You get out early because it is too boring.
  3. Plunge Face at the surface of an ice bath, ice on the water One song

    Ice needs a finish line

    Get in, finish the song, get out.
  4. Water Swimmer underwater, bubbles across the face Offline

    Swim time can be useful

    Bluetooth does not travel through water.
