Title: Audio Problem
Review: As with the DSP-500 headsets my company is using for their VOIP phone system, a test unit of this model also intermittently loses it's microphone audio--people can't hear me on the other end of the line--and the red mute light on the cord stays lit and can't be turned off. I've found this to be a chronic issue with these USB DSP headsets. You have to unplug/replug in the headset, then reboot--a total hassle in a corporate environment.On the other hand this unit is much lighter and more comfortable than the bulky DSP-500 units, and the sound quality is good, when it works.
