Calm Interaction Evaluation // OB-4
Calm Highlight
What stands out with the OB-4 is a new type of Bluetooth speaker interaction combined with a new type of function. The tape. On the one hand, the rotating movement of a metal disc indicates whether the device is currently playing music, regardless of the volume, but also allows the music being played to be turned back, scratched or remixed with an intuitive hand movement to rotate precisely this disc. The other is the tape itself, which endlessly stores exactly the last two hours of played content and can play it back if there is no device or reception available.
