damn, wish you hadn't said that
I bought a pair... LOL
So, I can't speak on the issues you mentioned and sure hope I don't run into them.
Sound wise these are a bit on the warm side but not to the point of being dark. It's a nice sound, I will be watching in case they go on sale in the next bit as I can force them to honor the sale price for the next 30 days which would make them more of a bargain to help offset any potential issues.
The included tips (all 2 pairs!) suck. So I slipped on the ever trusty Sony Hybrid tips and perfect fit. The shell design is super super comfy but does stick out of the ear so won't be usable for side sleeping. I will take them for a run and see how they fair in that fashion.
The case is big but kinda neat with the pull out tray. I have read they are not super loud which means nothing to me since I rarely listen at loud volumes. (Currently listening at just below 50%)
They are certainly not worth their full retail but at $77US or lower they might be a good option for anyone wanting something more geared to sound than features.
As I have been typing up this post I have been listening to several songs and they have a slightly elevated bass that go deep in the sub-bass region but it's done very nicely without out having to much mid-bass.
The midrange allows strings to have a nice sound to them, violins in particular sound very nice. Brass instruments also sound good.
The treble is a bit soft but not Sony level soft so has some sparkle to it. Listening to Patricia Barber I hear decent cymbals, decay is slightly rolled off but not to the point where I feel like I am missing to much detail.
I have also gone for a run mid post and while these have no ANC the passive noise cancelling is very good, to the point it was eerily quiet while running. Footfalls are as good as the Samsung which is better than most IEMs in this regard.
These are easily the most comfortable TWS I have tried. Much better than other other Audiofly products I have tried in the past and better than Samsung, Sony, Sennheiser, Technics, Status Between Pro, Anker, etc. The fit might not work for everyone though but I love the fit.
