I've just bought a Plantronics .Audio 995 Wireless USB, as a replacement for the Audio 400 DSP Foldable PC Headset I usually use for dictation. (The 400 is great, but I've had 3 break in 3 years.)
The 995 is working well, except that there is a constant hiss, even with volume turned down to the minimum. Does anyone know if this is normal? Or is mine defective? (Whichever way, the hiss essentially makes it unusable!)
Thanks
