Man, why did Beyerdynamic have to make it so hard, releasing 3 variations of 3 models.
Anyways, I tried DT770 80 Ohm Pro and compared it to Grado SR-225 (mine).
I have no idea how people claim 80 Ohm Pro is "bassy", they have very little bass compared to Grado 225s. Judging from reviews I imagined these would be basshead headphones that rival Beats in the shameless thump. But they have adequate bass, not excessive at all.
Also, people claim they have recessed mids, and yet their mids were way more forward than the distant sounding 225 mids.
Their sound is W shaped.
Grado has a "sharper" sound, but I can't hear instruments and details separately. I could immediately spot them on DT 770. Treble on Grado is "sharper", yet on DT 770, I noticed it more.
I have to say I liked DT770 80 Ohm Pro more.
I wonder how DT880s sound in actuality, because people claimed things about DT770 Pro 80Ohm that I did not find at all.
This guy's review is pretty spot on:
Although, I still disagree regarding the bass (but it could be the worn out pads though, he talked about pads changing the sound a bit on Beyers in another video).
