I have had mine for about a week now, and to sum it up, I'm quite disappointed.

I had high hopes, really, I did. Especially after reading Jasper's comments.

The compact case is really great, I think it's the biggest reason why I like them, but that has nothing to do with the actual headphones now, does it?

The sound is... well, I think it is in the same "category" as those street-style Sony headphones. Really nothing special. There is certainly enough bass, and isolation isn't bad, but I was hoping for better quality sound and more detail.

In fact, them being closed really gives me a hard time listening for more than an hour because the sound is so, ummmm, "stuffy", but afterall I did get them because of them being closed, so no complaints here.
