Snom A330D USB headset delivers excellent HD audio quality across the entire human auditory frequency spectrum thanks to modern D/A converter technology and optimised speakers. The soft on-ear cushions with 3 adjustable axes, are very comfortable to wear - even over several hours. Most background noises in the environment are suppressed. The entire voice band is recorded using a high-quality microphone, digitised and then transmitted via USB to a computer or IP desk phone, which enables the A330D to be used as a headset with almost any communication software platform. Both selected hardware and 1 software as well as the integrated remote control can control call functions, mute and availability and display them through LEDs on the right earpiece and microphone boom.
