Could have turned out to have been an unfavorable sound sig or lack of hype. The audio world has been going by pretty fast for me personally after being away from head fi for a week and upon my return I am already intrigued by many new headphones. Never heard or read about the h-150 and only just recently heard of the h-300 myself, so if I were to craft a theory possibly the hype got sucked out in favor for another t-peos iem.
Ok so T-PEOS came out with a dual dynamic driver/single BA hybrid IEM, H-150, and there's almost no info on it, even with current prices going for $100.00. WHY IS THAT? Did they turn out to suck? Even for someone who isn't a fan of T-PEOS, this seems an intriguing concept.
