Alright...I finally have sometime to compare a few of my (mid-fi) bass heavy headphones, here are some of my thoughts on the sound of their bass only (please keep in mind that I'm still fairly new in the audiophile world, so these are NOT expert opinions..lol):Sony xb1000
The bass on the xb1000 is very good and goes really DEEP (feels like being punched constantly in the brain). I have heard many people describing them sounding as if they are in the center of a club when they are listening to them. They are right!!It's good for when you're in a clubbing and heads-shaking mood :PV-Moda M100
I think V-Moda has done a very good job on the bass of these headphones, it sounds very unique and different to the other ones. The bass sounds much quicker, more defined/refined , clean and punchy (feels like I'm being punched constantly in the brain, but much DEEPER into the brain with these).It's good when you want some quick punchy clarity bass and brain damage.Ultrasone Pro900
Their bass sound very good and deep too, and I haven't heard any distortion like some people have reported. The bass on these headphones are definitely much DARKER though. It also sounded much SAFER. SAFER? Yes, SAFER...it's almost like you're being punched in the head with a thin pillow between your head and the headphone. No wonder Ultrasone claims that they have safe hearing Technology in them; now I definitely believe them.It is good when you feel like no brain or hearing damage is needed on those days.Sony XB500
Pretty good impacting bass too, but sounds much more boomy and muddy in my opinion.
So....at the end of the day....they all have very GOOD bass with different characteristics!!
