I know there are many threads out there, but I've tried asking on those threads and people just ignore my questions. Anyways I own Sennheiser HD 439's. the soundstage is great, good mids and highs, they are really light and super comfortable. But I'm looking for the two things they are lacking:

-Bass
-Reduced sound leakage

I know the sennheisers have bass, but I am a basshead. I want ear rattling bass. I've even looking at a few headphones in particular:
V-Moda Crossfade LP and LP2
M-Audio Q40
ATH-M50

My budget is 200$. 150 is my comfort zone but if they are that good then 200 is my max. I will not be using a pocket amp, and I am also looking for circumaural,
Closed back headphones. Thankyou

My advice to you is buy the v-moda. You've been asking about them a lot, so I say kill your curiosity and buy them.
 
My personal opinion is the M50 has very little bass, the crossfade has the most bass out of all 3 but the sound quality is the worst on your list, the Q40 sounds the best and the bass comes close to the crossfade in regards to quantity.
 
M50 - Best isolation
Crossfade - Bass quantity
Q40 - Sound quality.... For a basshead it has a great combination of bass quantity/quality and mids and highs, non-basshead will probably prefer the M50's sound signature.

Thank you, this is the type of answer I was looking for.
