Great value Plug & Play USB Headset Compatible with any softphone, as well as laptops with no software downloads. The JPL-502S-USB is the monaural equivelant to the JPL-501S-USB and features a single sided headband for office or call centre environments where users need to be aware of their surroundings as well as the call they are on. Thanks to a ratchet microphone boom arm which rotates 270 degrees, the headset can be worn on either the left or right ear giving the user full control of their comfort for prolonged use. Our Surround Shield™ noise cancelling technology provides excellent sound pick up from the boom microphone while the 55mm earpiece gives clear audio.
