I've also listened to the AKGK701, k81dj, k530, Beyer DT990, 880, Alessandro MS1, MS2i, Senn HD580, Denon AH-D1000 & a few others... and I prefer the ES7 by far, it may not be perfect, but it is a bloody fun headphone to listen to. It always gets me grooving and toe-taping to the music. Beware of the long burn in time though. I think most people who hate the ES7 never gave it enough burn in time. I remember I was not impressed with it when I first got it (read links in first post), but decided to give it about 500hrs burn in. All I can say is =
There has to be a reason why ebay is full of fake ES7s. As the saying goes, "Imitation is the sincerest form of flattery"...
If you can't tell by now, I LOVE my ES7.
The ES7s are a hate-it-or-love-it kinda headphone, either you love it or you don't. So take my words with a pinch of salt, best try it out for yourself when you're in japan.
