This version HALLO Acoustic + achieves 45dB of sound isolation thanks to its one leaf sound control door.

Our original HALLO booth has a hinged folding door and achieves 25dB. This one is suitable for coworking spaces and to be installed in corridors since it doesn´t disturb any emergency exits. It is inspired by the German phone booth of 1978 (TelH78).

The HALLO Acoustic + though achieves our excellent sound isolation value which we are used to from our FOCUS booths.
