Pros: Wide soundstage, extremely comfortable, blocks out sound, people can't hear your music, very durable, good for all music, best allrounders under 500$
Cons: heavy cord, you will need a good source to get the best out of these.
I am completely re-doing my review on these headphones because I think that these cans deserve it!
I would say that the beyerdynamic dt770 pro 250 ohm are the best closed back headphones under 500$ or even perhaps 1000$ if you have a good enough source to bring out their full potential. I say this because these headphones offer a true uncolored sound that stays truthful thoughtout the whole frequency response. Nothing is boosted in any way but these are tuned to deliver a completely flat response with little to no distortion.
Bass : The bass is strong, tight, controlled, and does not get boomy or muddy unless the song itself is not properly recorded. You will not hear bass this good in a 180$ dollar headphone. The sub bass is the best I've ever heard yet. It is well extended and very present with a satisfying rumble that can please a basshead. The quality and quantity are both good and could satisfy anyone.
Mids : Not ressesed at all but the mids are full and lush with a lovely separation of instruments and live sound that gives the music energy and punch. Also super clear with good resolution and definition that gives you everything in the song.
Highs : a little on the soft and dark side but very smooth and plentiful. Some might want a warmer sound or even a brighter sound but you will love how easy it is to listen to these cans.
Soundstage : The soundstage is super wide and has amazing instrument separation for a closed back. These do not sound like it's in your head but the music surrounds you and sounds very realistic.
Comfort : The comfort of these headphones is on par with the hd800s. Which are some of the most comfortable in the world to date along with the Philips Fidelio x1.
Durability : These are made with metal and high quality plastic that will last a lifetime.
