Well,Sennheiser HD650 comes with a beautiful looking carton which makes it a really precious collection ,but Sound quality is what really matters when it comes to headphones like these .

Sound quality

I have used them for around 400 hrs and just after 100 hr bass which was little muffled, got deep and articulate.


Well, These have laid back character with rolled off high, which makes them very pleasurable to listen music with them, as highs are not very harsh on ears.



Bass: I know many people are only concerned about bass and all and I must say they are not very bassy like my DT770 pro 80ohm ,but IMO HD650 are way ahead of DT770 pro 80ohm .Its mid bass is very deep and very well defined ,whereas bass of DT770 Pro 80ohm is very boomy and not defined at all .

Treble :Its treble is really good ,but its highs are little rolled of ,thats the reason they are very smooth sounding headphones and sometime people refer that these have laid back character .



Headphones tried with different Genre's like Classical (western eg Schubert ,Beethoven ) ,Indian Classical (eg Ravi shankar ),Rock linken Park ,Led zeppelin etc,POP,Trance (Ministry of Sounds ,Tiesto etc),Instrumental etc
