My work phone is VoIP via my computer and I log about seven hours of phone time daily, so my headsets get hard use. I've bought and used both Logitech and Cybertronics headsets. I really needed a headset that travels, and bought this one in fall of 2007. It's now spring of 2009 and they are starting to degrade. I would say that is excellent service, given daily hard use and the rigors of travel. I'm now getting static and voice degradation, and am looking to replace, but nothing out there looks compatible and affordable. So I will probably buy these again, and look for about 18 months of good use.
