The Poly BT600 is a Bluetooth USB adapter that connects a compatible Poly or Plantronics Bluetooth headset to a PC or Mac. It gives the headset a dedicated wireless link to the computer rather than borrowing the machine's built-in Bluetooth, which is where most call-quality complaints on desktop softphones start.Because the adapter is pre-paired and purpose-built for Poly audio devices, calls connect cleanly and music plays without the stuttering and dropouts that shared Bluetooth radios often produce. It is small enough to leave permanently in a USB port, so the headset reconnects the moment it is switched on and there is nothing to set up each morning.Sold as a spare, so it suits replacing a lost or damaged adapter, or adding a second one to a home office so the same headset works at both desks. Check the adapter against your headset model before ordering, as Poly Bluetooth adapters are matched to specific device ranges.
