Don't know what to say really...
The HS7s are my first studio monitors ever and I have to say they don't sound as "****" as I was expecting, but they definately don't have the punch the KRK 6s have, and they sound "thinner". But of course just like some people have stated, the KRKs are way more hyped than the Yammys.
Overall they're nice, 320kbps mp3s sound enjoyable and I don't find them harsh sounding at all. Recommended.
(The KRK comparison is based on my friends monitors)
