Would you like to hear a little less bass? A little more treble? Would you like to cut out a lot of the background noise and not have to strain to understand what people are saying? With HearPhone software, the pitch and loudness can be customized to suit your particular listening preferences. You can choose a little noise reduction or a lot. When you just want to hear sound from in front of you, you simply press a button on the headset – the directional microphone technology is built-in.
