Bass in my opinion is up there with the top 10's I am just waiting on someone else to get these and confirm what I am saying you will be surprised by the bass on the headphones hopefully someone gets them try them wireless and then amp them with your guys setup and push them you will see what I am talking about, the headphones is on par with the ath pro700mk2 in the slam. the xb1000's are king for subbass and the sz2000/1000 are king for midbass and the bluedios are the king for wireless bass but can go the distance when amped on there own.
I'm not trying to disagree with you or any of that sorts. Please just take it as my experience with my gear.
I have been A/B/C xb1k/sz1k/UFO
The xb and sz can pick up those very low notes. I cannot say exactly how low, but i would imagine a few notes below 20hz as i can feel air from both with no sound (as those below 20hz is inaudible). The UFO struggles in this area, but with EQ, it can be noticable, but still falls short.
xb and sz probably are equal in their abilities, but the sz seems deeper and tighter, which i think because the xb is vented and semi-open, which makes it slightly cleaner when eq'ed and amped properly for soundstage/imaging/vocals. Please keep in mind the xb/sz are IMO not the best for music listening like something like a 770.80, which is just more accurate overall. They are not worlds apart, but you must keep in mind the purpose for the tools, and your music needs.
The UFO wired can be bassy , no doubt, and its growing on me, and impressive for wireless.
But, the sz is just too beastly Its very hard to compare these three, but a track like this makes it very apparent
the xb/sz moves more air (inaudible) than UFO. In other bass tests where the notes are 20hz+, its closer in a sense of their abilities, but still noticeable.
The great thing about UFO is it seems to stay stable, so i hope someone can pair it with something beefy and find the magical eq settings. Also, one thing that concerns me is the earpad hole. ITS TINY! a 2 knuckle hole. I might try other pads with larger hole so those tweeters and mid driver is not congested by pad, which i think is happening.
With some experimenting with pads (hm5/xb pads maybe, some other large hole pad) i think the drivers can breathe more and less interference and will make more air. Stock ear pads are terrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrible.
Its verrry bassy, i would imagine more than p7/p9 wireless, but sq i would imagine easily beat by B&W.
These do movies well. But I would imagine better with a pad change.
As great as some of the features are (12 drivers, metal construction,), please potential buyers keep in mind (poor designed headband, slight rattle, poor ear pads)
It might be a can to tinker with, but not one you want to dump coin into.
IMHO n YMMV yada yada yada
