I'm no hi-fi buff, and, 'perfect sound quality' is beyond my understanding (bit like feeding pigs cherries I suppose), but, I have a particular requirement, and after weeks of searching - haven't found what I'm looking for. So, I've come to the 'people in the know'. Basically, what I want is more for comfort than sound quality and maybe I can't find what I want because of incorrect terminology, but, here are the criteria: 1) 'Tension' neck-band (not resting on the top of the head, as they get sore after hours of use). 2) Full, 'cup' earphones that surround the ears (not rest against them). 3) USB with microphone. 4) 3.5mm jack (microphone not required). 5) Sound quality is low on my list of 'must-haves'. I understand that I'll need to buy 2 sets (USB / 3.5mm jack). It may be that I'm asking for too much, but, I suppose here is where I'll find that out. Any pointers appreciated.
