Beautifully designed in basic black, the Plantronics Audio 655 DSP Headband Headset offers a full range of audio, with frequencies from 20Hz to 20 KHz. Inside the earpieces are high-quality 40mm speakers that isolate you from the noisy distractions in the area, and these ear cups are rimmed with soft padding for superb comfort. Whether using the headset to take work calls or enjoy game audio, you can use the attached microphone to speak to clients, colleagues or chat with friends who are gaming online with you. The microphone cancels out most external noise, bringing your voice through loud and clear to the listener. Connect the headset via USB to enjoy full digital stereo performance.
