Just got my pair of MK2 yesterday and so far one thing has been really bothering me. The treble on these is insanely harsh and noisy, almost to the point where it's just noise. The cymbals and hi-hats are like lightning bolts. I heard they require at least a 100 hours of burn-in before they "even out" and come into their sound. Is it true or have i just got some kind of faulty build?
The composition of the drivers in this iem REQUIRE that you burn them in for a considerable amount of time. People can argue all they want about other iem's and hp's with regard to burn, BUT the bioceluse material in this iem need about a weeks burn in time or 200 hours. The are a completely different hp after that.
