Headphoneus Supremus
I'm sure this iem is great, but it seems a bit ridiculous to me that it needs 350 hours of burn in to sound its best. I don't understand that.
I routinely burn EVERY earphone I receive across the Board 200 hrs. minimum. The BA take MUCH longer than Dynamic drivers to hear any change, if any. Burn-In doesn't always change an earphone.
This prevents people saying "Well this phone isn't all that, or this earphone sucks" then coming back later and saying "I've been listening more and XXX earphone is GREAT"
I've seen this play out RIGHT HERE ON HEAD-FI time and time again.
My advice: Burn them in, even if you think it's Hokum, then give them a fair shake. If they SUCK they won't change, no matter HOW long you break them in. (Earmax ER610) It had to die.
BTW: Fat, we didn't arbitrarily come up with 350 Hrs. These Earphones have been available in Asia for quite some time, There are MANY reviewers on TaoBao stating this opinion.
