(About 385s)
So, I know that we all have our burn-in processes. Some use White/Blue/Yellow noise; a lot of us use EDM. My process for burn-in goes as follows:
12H of EDM, 12H of Classic/Opera, 12H of Pop/Dance, 12H Rock, 12H Nu-Metal/Progressive, 12H Rap/Hiphop (Old-School & Underground @ 8H, Mainstream @ 4H), 12H of Blues, 12H of Solo Instruments (Guitar Solo, Drum Solo, Violin--big one for me as I love violins--solo, ETC) than I repeat the process until I feel the headphones are burned in thoroughly.
So, I finished up the EDM & moved on to the classic/opera playlist. After about four hours I heard something extremely unique. The sparkle that I heard from the other-day has subsided a tiny bit into something more detailed & dry. Now, the sparkle is still there it is just moderately-low instead of the moderately-high that it was the other day--nothing to the point of FX40 brightness--and because of the extremely tight--read: the bass has improved exponentially, it is refined and blends so well with the highs--lower frequency the headphones are given a unique-ish sound.
Sadly, that is the last of the good news though because the mid-range still hasn't improved that much. Sure, because the bass has tightened up I can hear the mids a little better, but they are still recessed behind the highs & lows. Don't get me wrong; they are everything that Mochill has said they are, but compared to the other spectrum they just feel bland right now. Nothing good or bad about the mid-range with the exception that a headphone with this much bass & highs actually has clear mid-range that is.
I'm glad that someone else thinks they are - almost - balanced, I thought I was going mad!.
I was just about to post that we have two drivers to burn in not one, so may evolve at different rates - but you have that covered.
The Quadlons at there current stage of development sound better than the Xears - Xears over did the sub bass and they are slightly veiled when compared to the Quadlons.
I would bet we are listening to the same iem, one with a detachable cable and the other not. I would also guess that Xears did some of there own stuff to the 4core (own shells to start with) and possibly upset the balance, unless you really love sub bass!
Did you get any foam tips with the 385s? - if you did, don't use them!
Sorry for not getting back to you the other day, mate. I just wanted to let them burn-in on their own before giving them another listen.
Yeah, I can tell that they are balancing out but at the moment the mid-range is still lacking some essence compared to both the other spectrum. My headphones started out with the bass veiling most of the other spectrum, but they were still listenable, and has severally calmed down into something quite spectacular for how much I paid for them.
Nope, I wasn't looking for foam tips for the 385s. I was looking for some double or triple flange tips or anything that is a bit higher quality than what appears to be the Dollar Store ear tips that my 385s came with. The housing and packaging is so nice but I could have spared the packaging for some plastic if they would have included some quality tips and a little cable management.
