Ive been using mine for a day or so. The most important part for me in audio these days is comfort. I do not care if your product is literally flawless, if the comfort isn't there, it's pointless for me.
They bring that for sure, love the fit, and I've said this when the first ones came out. IEM makers have to stop it with these nonsense thick metal/pastic stems you have to shove in your ear causing annoying pain, or having to use basically one time use foams to rectify partially, the tips need to stop being circular, and more ovular like these are.
The sound though. I can't tell if it's because I've only had the chance to listen to Apple Music offerings, but I'm regularly seemingly hearing some sort of distortion when the bass or certain treble hits heavy, this could be because so many of these tracks are horns/brass heavy instrumentally, and it seems the entire recording industry is riddled with garbage recording engineers and are having their recordings clipped, and on top of lossy compression, it's just very apparent on these earphones.
The other thing is, I sometimes cannot hear the mid's all that much. All this talk about improved bass is actually real, improved in the sense of extension, I'm not sure if it's improved in terms of representation of being distortion free, but man do the tracks punch. This seems slightly over-tuned to be perfectly honest at times, and I'm not sure if this is drowning out the rest of the music because of it at times (we're talking about IEM drivers here and all). Idk what's going on but things feel quiet until I ramp the volume up considerably.
