Product Description

The USO handset combines high-quality technology with an attractive, sturdy design. With its compact casing made of soft-looking PVC plastic, the device sits comfortably in the hand and is particularly resistant to impacts and breakage. That and its excellent sound properties have made this handset a trusted museum and exhibition accessory for many years.

The handset is held on its base by a strong magnet. This allows it to be picked from all directions and returned safely to its original position, even if it is placed inaccurately. When the handset is picked up, reed contact is activated and the audio starts playing automatically. When the handset is placed back on its base, playback stops.

A button or rocker switch can be integrated into the casing cover, allowing the user to switch between two languages or play different audio tracks. These options can be labelled with either engravings or stickers on the casing cover.

In the standard PVC version, the USO handset is available in the colours black, dark grey, and white.

A robust, flexible stainless-steel tube protects the connection cable and reliably secures the handset.
