TP-Link’s UB400 turns Non-Bluetooth PC or laptop into Bluetooth-capable. Just connect your Bluetooth devices to your computer and enjoy it with ease. It supports 7 Bluetooth devices at most. With a transmission distance of up to 20 m, you can enjoy lossless music via your Bluetooth headset without hovering around your computer. A sleek, ultra-small design means you can insert the nano adapter into any USB port and simply keep it there, no matter when you are traveling or at home.
