Where do I start. First of all let¡¯s mention that I¡¯ve tried a lot of headphone in my life with many different style and brand, I¡¯ve tried the Beyerdynamic dt770 pro, Sony wh1000xm4, Focal elegia, bose hp 700 and much more. All of these headphone are good pair of headphone but they where all made for different need. I do agree that the HD 660s is the best headphone that I¡¯ve ever tried in my life.
Fist let¡¯s talk about Comfort, the HD 660s is very confortable but you won¡¯t forget him, the clamping force is pretty high and will squeeze you head if you have a big head but after a few days it will get better, except this, these are very confortable headphone.
Seconde things that i want to point out is the noice canceling, truly awesome, just kidding this is an open back design that men you can hear the outside and the outside can hear you. So keep in mind that for a good experience you will need to be in a calm room.
Last but not least, I will say of course the most important thing in a pair of headphone is the sound quality. First if you like beats headphone or headphone with muddy and heavy bass save your money. The bass on this headphone is really good but you won¡¯t feel it in your head, the bass is just sooooooo well defined and clear, I agree it¡¯s lacking a bit in the sub bass area but that is just depending on what music you are lessening. I do want to mention that even if these headphone are only a 150 ohm with a sensitivity do a 104 dB don¡¯t try it with your phone it will sound like a cheap pair of headphone. I don¡¯t have a dedicated amps but they work pretty well with my gaming laptop who support Hi-Res audio but I agree that is not the best experience you can get out of this pair of headphone I will buy and amps soon to make sure I will have best experience possible. Anyway let¡¯s continue in the sound quality by talking about the mids, damn they are good they just sound natural you feel like the person is talking right beside you, this is where these headphone shine the mids a just so well reproduced. Finally the treble, there is not much to say I¡¯d you look at the frequency response graph they are not particularly present but are not sibilant at all they are very good, a good definition just what you like.
I highly recommend this pair of headphone you can go wrong with this especially if they are in sale
