GN 2110 SoundTube headsets are the first ever to use Acoustic Transmission Line (ATL) technology, the first significant advancement in voice tube technology and design. ATL technology has higher microphone sensitivity than traditional voice tubes because of the type of microphone and position of the microphone filter. Traditional voice tubes have lower microphone sensitivity than the SoundTube. The end result is a rich, full, and natural sound. GN-2110-ST Features:

• SoundTube with omni-directional microphone
• ATL technology eliminates sound reverberations and distortions
• Swing-Away Boom
