These have had a lot of ear time since i have had them with me and may i say, im starting to understand them. The bass is as amazing as ever, i mean, there really is little to complain about. The mids do no longer seem so thin, maybe because i am starting to appreciate where they are meant to be in the music and maybe also due to a bit of burn in. For certain though i do not think they are thin, they are well positioned (for the most part) and oh so detailed and the midrange balance is just great to my ears, it really shows some unbalance in other earphones such as the Musical Fidelity EB-50 that i painfully wore in the gym today (cant risk it with these can i
felt so un even, the tilt toward the high mids so glaring towards me. Treble i have made little comments on so far because well it offers sparkle, an nice air and is not fatiguing. So yes you could say i really am falling for the sound as i just read that back and it looks like i am struggling to find faults. Maybe the midrange could just have a bit more presence, i get the whole stage thing but some times they do feel like the vocalist is a bit too behind, not thin like before but just a bit weak at times. Also the bass can really spring up in some songs but perhaps a tad too much, i dunno thats just my preference but technically the bass really is jaw dropping. The signature is certainly U shaped to my ears at this moment and the bass is clearly boosted, especially towards the sub-bass and the treble more forward than the mids.
I do however find the cable stupidly microphonic, unflexible and very chunky for portable use, it is thicker than my HiFiMAN HE-500 cable for example (much better quality that it however).
Also i just wish they sat nicer and more flush in my ear, like the Heir IEMs and the UE900 do. They feel just a bit bulky in my ears and also the small bump causes the slightest amount of discomfort.
