*Discontinued*  Replaced by Jabra Jabra Biz 2300 QD Mono Noise Canceling Headset 

Jabra/GN 2120 Flex series noise canceling headsets are ideal for demanding applications, especially noisy environments. Jabra GN2120 incorporate a flexible boom which ensures correct microphone positioning, and a noise-canceling microphone that filters out distracting background noise. GN2120 is lightweight, very durable, and extremely comfortable, even if worn all day long. A click-stop headband provides a customized fit and pillow-soft ear cushions rest gently over the ear. This model is a monaural headset (you hear through one ear), and the Jabra/GN 2125 is binaural (two ears) -- which improves audibility of weak voices and blocks out distracting ambient sounds and nearby voices.
