I need some cans for my Yamaha motif es synth keyboard. I bought some sony mdr-7506 and found them really harsh so are going back. What will sound better (more appropriate) for listening to blurays through tv, and also using for music and my keyboard. I understand beyerdynamic dt250 80 are more studio headphones,but will they still function for my needs? Or will the sony mdr-1r (more hifi than pro) be better? I want a realistic sound as I play a lot of piano, please help as I need to purchase some cans tomorrow.
