I had the Pro700, and took them back because they were very uncomfortable. I did't even have time to break them in.

Do they need much to push them? I will be listening via my LG G2 phone and my HP laptop with the Beats audio. No amp.

I want the most bass heavy cans I can find...BUT I want tight, accurate bass...NOT boomy or muddy. I would also like clear highs and warm mids. Any recommendations? I've heard the Sony XB series, and I'm not a fan of the sound so don't recommend those please. Thanks.

How about the bass on the MDR? Is it as tight and accurate as the M50? Is it more or less quanity than the M50?

You should consider putting the Sony Pulse Elite headset on your list. The bass impact feature is pretty awesome to me. I think they are some really fun cans. And the bass is adjustable so you can get it right for each individual song. And you can snatch them up for around $115 online.

Has anyone heard anything?

Finally got the MK2s in yesterday. How they feel: they're very tight out of the box so quite a bit of stretching will be needed. I have average sized ears and mine barely squeeze into the small round cups (if you have larger ears, these will be on-ear for you). The ear cups seem pretty shallow...

Anyone heard the Audio Technica ATH700PRO MK2? I've heard they have more bass than the M50.

Anyone have the Audio Technica ATH-PRO700MK2? How's the bass on them?

Went by Guitar Center today and picked up the 750DJ cans. They're the most uncomfortable cans I've ever put on! The head band is more straight than curved, and the ear pads just felt off, and didn't really seal securely. Straight out of the box, the bass is weak. And they're too uncomfortable...

The Shure SRH750DJ cans are the most uncomfortable cans I've ever tried on! And the bass did not impress me, unless they have to be burned in before they really pound, but I didn't care to wait and find out.

Well, I just ordered the MK2 from Wal-Mart (of all places), but they won't be here until December 11th. I guess I'll go get the 750DJ from Guitar Center to audition while I'm waiting for the MK2s. Both places will have easy returns if I'm not satisfied with either , then it'll be back to square one.

Anyone heard these?   Comparison points I'm looking at are: Bass? Quantity & Quality; Highs and Mids? Quality; & Comfort?   I'll be powering them with my laptop and iPhone 5. I listen to 85% hip hop. I love bass, but I want it to have quality.

Has Sony said nothing about fixing the rattle problem on newer models?

They're not open, but have you heard the Sony PS3 Pulse Elite? The pulse technology is awesome for gaming and music, and the bass is adjustable. They can be wireless with your Playstation (if you have one), and they have a detachable cable.
