How good is the HPA2's microphone quality?
Really good. Clear and adequately loud, and it's flexible so you can put it where you want it. I can bend mine away from my mouth to eat or drink a beer and still be heard absolutely clearly. The mic is why I got these in the first place.
Absolutely SUPERB
I agree that the sound quality is very good but there is a defect with the microphone that unfortunately has never been fixed and it will affect all HPA2's eventually. However, it's not the end of the world and its very easy to fix and only takes about 2-3 minutes. The wiring in the microphone (due to the design) can get pinched which causes the microphone to stop working. To fix it, you just pop open the microphone and move the wire off to the side, close up the microphone and it's fixed. Had this happen to me and I thought it was a dead microphone until I read one some forum about this issue and fixed it myself.
That has been the only issue I've encountered with the HPA2s and in my opinion, it's such a minor issue that shouldn't keep sway anyone's mind to not getting them. I just wanted to post it in case anyone experiences their microphone going south on them and are worried its dead.
