Thanks for the reply.
I'd intialy assumed a low end mic too, but from the little I could understand people seemed to be having conversations with no issue - it also seems unlikely that EVERYONE that I encounter has a poor mic.
As for the sound, I play with a Corsair Vengence 1500 head set at about 16% volume (on PC, I completely failed to mention that!). So, it seems unlikely that the distortion is a result of over-doing the volume.
Also, it's ONLY the voice stuff that I'm having any problems with, the rest of the game sounds good even when things get a little hectic.
