Summary: Coming from Senn PX200, I expected better highs and better bass. I was drawn towards this AKG due to recommendations on this forum.
Well, my experiences are less enthousiatic than those of most others.
Audio quality is 'not bad' at best, but in general there's always a honky bass covering up the rest of the music. A lot of people here praised the bass qualities, but to me, it's not real bass, it's somewhat higher up the frequency scale. It's where it's starting to honk.
