So, these are interesting...
Got #18.
I have to say I expected these to be bass cannons on first listen and with the "Taction Technology" turned off. You know, usual, cheaper closed-backs are usually a bit warm with sucky bass. Turns out, they are PRETTY TAME! Haven't run specific test/bass sweeps but I'm pretty sure ALL of my headphones at home (Ultrasone Signature DJ, Sony MDR-Z1R, another cheapo I don't even remember) have more bass presence/go lower. Signature seems fairly neutral/bright actually!
But then you turn on the Taction button and ... an awesome boost with excellent tactile response. It's definitely massaging my face right now. They lack a bit of clarity and energy somewhere, can't pinpoint yet but it might be mid-bass, need a few days/weeks and my gear (I'm only using them directly from my phone which as you all know, might not be the best test bench...).
All in all, interesting cans, and surprised they are not too weird sounding with the tech off.
Cons for now:
1) Not super comfortable, especially the pads, but they do a good job.
2) Cable is on the right side of the headphones
3) Exposed cables on the sliding mechanism (not sure how long they would last)
4) These might pose a problem to people with long/big heads.
Will chime in with more details later.
