In today's retail and healthcare world, more and more employees need to have their hands free to take notes, serve food or carry things. The WHM621 with charging cable is a DECT headset that works with the W70B/W80 Multi-Cell System/ W90 Multi-Cell System DECT base to provide this flexibility. The headset can log on directly to the DECT base as a standalone device or share a SIP account with a DECT handset to dial out or manage the call. Thanks to DECT technology, the headset can provide a stable connection and an excellent range of up to 300 metres. So you can move freely without worrying about the headset's range.
