I am using my HD650 for all purpose right now   They are very good for gaming and movie as their nice bass.

Grado RS1i  so beautiful!!!

I dont think there is fake M50s in the market!

Sometimes, engineers use this difference to make different sound I guess

Probably because of overpriced ! I got beats studio as well, SQ is just ok comparing to normal headphones

I have you say for sound quality, Momentum is much better than Studio 2.0 which is much better than old studio   But my ears are too big for momentum over-ear, so studio is much comfortable for me.    If your ears are average size, just you wont go wrong with Momentum over ear

someone told me if you got the money for HD800+HDVD800, you'd better save that money for STAX 009 system

any common on HD650+HDVD800??? Can HD650 be fully driven???

IMO they are very similar, I feel HD650 a little bit warmer than 600! and got much more bass as well!

I am just not getting use to their cushions, feeling weired!

u may want to try Grado SR80i??

maybe grado's would be easier to drive??

they look very cute , but I think they are just for fun! or Star war big fans!!

I think you should try other brand or or HD800 if you want to stick to sennheiser.

Have been using HD650 for a year, I use them much more frequent than my T5p! Now I decide to sell my T5p   HD650 is much more comfort than T5p to me!
