The high-quality speakers provide a brilliant, powerful sound that is particularly impressive when listening to radio plays, music or soundscapes.

The automatic activation allows visitors to immerse themselves fully in the exhibition, as no interaction with the device is necessary during the visit. The highlight of the supraGuide SPHERIC is, of course, its multitrack 3D sound. This allows binaural recordings to be linked to the compass in the device via software. The result is a fantastic spatial sound experience that makes every visitor smile.
