these are the first cans i ve ever brought...but i ve tried beats studio,solo's,skullcandy hesh uprock mix master and i can say that for this price and sound it beats all of these in every aspect,the bass is awesome but not as puncy as i was expecting....dont knw about the 600 and 800,the ear pads are comfy but of low quality and it looks like it will hardly last for a year or so...the db is very less which forces me to hear these at full volume on my bb,with the ipod these work great but not with my ipad,100 db is way to less...in india these costed me around 1700 rs...which is aprox 35$..the conclusion :- awesome headphones for this price
