confusion dilemma: Ultrasone PRO-750 vs. Ultrasone HFI-2200 vs. Sennheiser IE8

[i_don't_know]

I've done my research, and this is what it's come down to. I'm coming from JVC HA-RX700. I know these threads are getting redundant, but I've been posting, finding something new, posting again, etc. I think I might have finally narrowed it down.

I like something that is very fun to listen to (deep/tight/punchy/undistorted/unbloated bass, engaging mids and highs, rich and full sounding, etc.) and has superb soundstage. I hate harsh highs, sibilance, and fatiguing sound (my ears are very sensitive to those sorts of things).

It's important for them to be able to be fully driven unamped, straight from the headphone jack of a DAP (Sony S639F) because I don't own an amp or plan on buying one.

I listen to a lot of Oasis, and some Muse, Jack Johnson, Devendra Banhart, Andrew Gorny, and Matthew Santos. So, to be as simple as possible, rock, folk, and bluesy/jazzy acoustic music.

Music samples:
YouTube - Oasis - Live Forever (UK Version)
YouTube - Devendra Banhart- Long Haired Child
YouTube - Andrew Gorny - Beatin' Tha Guts
YouTube - Jack Johnson - Sitting, Waiting, Wishing: Album Version (Edited), Closed Captioned
YouTube - Matthew Santos - Shadows in a Shoebox - www.candyrat.com
YouTube - Muse - New Born (Full Length version)

I don't care about isolation, size, leakage, or any of that fancy stuff. The sound is all that matters.

And I'm hoping this will be the last of these threads I'll have to make, and that you guys can help me finalize a decision. Thanks for bearing with me, I know it's been a little excessive. The sooner I make a decision, the sooner I'll be able to stop making these threads.

I can't find much info on the Denons.

Ultrasone PRO-750, HFI-780, Denon AH-D2000? Grado Fan Needs Closed Cans
Ultrasone PRO 750 vs. Denon AH D2000

use the search button there are plenty of AH-D2000 headphone reviews / opinions.
They are closed overear, doesnt isolate particularly well from outside noise but dont leak like open headphones, but from what i read they are better/similar to the Ultrasone Pro 750s sound quality wise. They also have a considerably more comfortable headband.

According to what I read, the D2000's bass is a bit bloated without amping. As I already stated, I don't plan on using an amp, so it's still between the original three. Thank you for helping, though.

well the denon have a lower impedance (25 vs 40 vs 75) and higher sensativity (106 vs 94) than any of your current choices (except IE-8). So i doubt all your choices would be any better without amping. Which the Ultrasones definately needs to improve on the bass, and plus the longer burn-in times is required for the Ultrasones

Also i dont understand what bloat means. the Pro 750s bass to me is bit muddy and fairly deep. I dont have an amp at all. (unless the Sound card, and my Hi-Fi system counts)
