[Sonic Diamond™] HifiMan RE0

Sonic Diamond™ is a rating I give to what I believe to be the absolute best valued IEM in the market. So far, this title has never been given to any IEM though some come quite close. Well, that is about to change now, even if it is only going to last during thissummer.. Head-Direct RE0, or now known as HifiMan RE0 by Head-Direct, is having a summer sale promotion, smashing the usual close-to-$200 price tag to a mere $99 (and comes with a free FiiO E3). This is a deal you don't want to miss out. Want to know more about RE0? Read my review over at Head-fi (beware that Head-Direct has updated the cable to fabric 'knit' type since the review has posted over 6 months ago).
