Hi i was thinking to buy Corsair HS35, but i saw that in this forum that it was a good idea Superlux headphones and a lavalier lapel microphone, and i think that it would be ok, so i look for those headphones and i saw HD-681 and HD668B models but they are open back, and i would like a closed back instead, would you recomend me one good pairs that cost less than USD 40? and a good cheap lavalier lapel microphone, thz
