This is a spare/replacement PR receiver unit for the Sonumaxx NX system (not compatible with non NX systems).

With adjustable volume up to 122 dB, the Sonumaxx NX PR Headset System from Humantechnik has exceptionally clear audio reproduction and high-quality sound - reliable and free of background noise. 

This system is ideally suited for people who find the TV not loud enough but do not wear a hearing aid. When using this system the listening volume is independent of the TV volume.

A special feature of the Sonumaxx  NX Headset System is the possibility to switch from the reception of the TV sound to the built in microphone of the receiver so that you can listen to conversations too.
