I watched some of those negative reviews and as usual with alot of them I'm left scratching my head, so I've learned, as I'm sure you have to, not to put alot of faith in others preferences. They are a fun can, they are a fun can with great technicalities, if I want to dissect my music I'll listen to my HD800 or Hekv2 if I want 99% detail with a can that sounds beautiful with just about everything I listen to my T1.3.
Alot of the negative reviews I think are in contrast to other Beyerdynamics specifically the previous t1. I haven't heard it so never came at the .3 with that perspective, I did have the Amiron and still do, so it was love at first listen for the T1. If you give the T1 alot of time and play with ear placement you might really like it. The good thing is if you don't, they will probably sell fast. It's a very transparent headphone with a deep soundstage, they are my favorite headphones now
