Most everything has been mentioned, but if you like to pick by ear, I'd add Beyerdynamic DT1350. Really need to pick them by hand, as there is/was lots of variation.

As to the above ones... I'd avoid Q40 and V-Modas. V-Modas are really meh everywhere with super boosted bass, M-Audio Q40 is kinda anemic in general, having thin sound (and it's not lack of bass).
Momentums are also kinda eh sounding out of the box - way too dark. Really have to boost treble on the equalizer with these, and that is usually at odds with portable listening.

EDIT: mixed up Shure 840 with 1840. 840 was that ear tweeter one.

Love my (filtered, HD25-padded and 'bent' headband to suit my head) DT1350 but won't recommend it to anyone.. plus one needs to be lucky AND like it's signature. Not everyone does, I do (but with mods, don't like it without them)

call me interested in hearing the T51P (no typo there) and DT1350 'facelift' (also no errors here).
I expect/hope they have made some real improvements. 

I posted this in your other thread, but....

I'm friends with the author of that comparison piece, and I can vouch that he has good ears. He also doesn't approach things strictly from an "audiophile angle" which you might find useful.

Oh noes... a HF link! Quick, before it ends up being deleted! ...Oh wait.

They block head-Fi!  Sounds like a very good school!
 
 

That's a useful link MF.  Thanks.

Alpha pads are recommended and can be acquired separately, but I suspect that may be one of the older Revs of the MD if it has the Shure 840 pads.  Not sure what is considered the best version, but you still may want to ask the seller if they know what Rev it is...currently MrSpeakers is on 3.2.
