This product as you can see is a wireless headset. It is sold on it?s own as being an additional headset for the CL7300 wireless headset system. This additional headset comprises of large buttons for volume control, stereo headphones and an easily removable battery that simply slides out of the unit for swapping with another battery that has been charging in the main base unit.This 53gram headset comes with a spare set of rubber ear buds ? so you have a choice of two different type of ear bud for listening pleasure. Since this is an additional headset, we are pleased to advice that you can pair at least four additional headsets to the main base unit allowing multiple users to experience their favourite radio or TV shows at the sound level they want, talking of which, each headset can deliver a cracking 125dBsl, so no more annoying the neighbours or others within the home by having the sound at your preferred sound level.Once paired with the CL7300 wireless system, these headsets will allow you to move around with the headset still being operational up to 30 metres, allowing you to move from room to room, with the headset on. This will be especially useful if one is listening to a radio program. Up to 4 headsets can be paired to each base.
