Today I will inform you about a product that I found Sennheiser HD280PRO Headphone New Model. Sooo long procrastinated with the choice. I re-read, reviewed, re-listened_ I bought 280s and Audio-Technica ath 50x for comparison. At ath 50x, the highs and lows predominate, coupled with a slight dip in the middle. These Sinha guys sound very worthy, but naturally the amplifying path is needed more seriously than in gadgets. Good luck to everyone!
