I've tried this headset because I was looking for a new one. The Jabra has convinced me in terms of noise reduction and sound quality completely. The KO argument was the fact that it has not kept me on the ear - a short ruckartigere head movement and the headset has fallen almost by ear. Class office and noisy environments, but not recommended for head moving Tatäigkeiten. (After I tested the Plantronics Voyager Pro HD and there it was the other way around ...)
