Just received my Black Friday frosties!
First impressions (my daily use is airpods and er4-xr etymotics, have tried totl also like the 64 18 driver ones and Nobles, use to own brainwavz b2s and they became a firm favourite) also as you can see I don't own any multi ba phones at the moment.
Wow the mids are really warm and presented very intimately. This is how I love my jazz quartets and trios. Put saxophones through these and they sound amazing, very full and lush. Piano also sounds great and lush, unsure if it's an 'accurate' representation but I love it.
Bass is sufficient and surprisingly detailed at this price, but Campfire Jupiters and Noble Kaiser Encores will give you more in particular more detail on sub bass (ok this is an unfair but I'm just giving reference points I know) . Etymotics will give you less. For many picky classical listeners perhaps too much bass.
Separation is very competent for jazz, less so for Edm, maybe just my ears but it struggles to separate instruments but I am used to etymotics where detail and resolution. Cymbals are detailed but these are not reference phones so don't expect accurate reproduction, more fun.
Warm and smooth, with surprisingly competent trebles (I find cymbals very hard to replicate but these do an amazing job). One strange thing I noticed the presentation/ Imaging can sound a little processed or artificial, not a bad thing but it is something I noticed with audio technica headphones too, a phenomenon I don't get with my fostex th600 or etymotics.
These were priced well enough that I was happy to take a gamble, and I'm glad I did. I would be happy to use these daily and own nothing else. The etymotics rule the roost for me as dailies because I own them, but cost 5 times as much.
