To put it mildly: I hated them! Too heavy, too uncomfortable and the midrange was so far out of sync, i just had to get rid of them, after about 2 months that's exactly what i did. Now I've got the triples which i find far better in terms of fit and comfort. some may laugh at that, but i do, the triple are better.
The bass is good and strong, and deep, but as a package, i just couldn't get on with them. maybe one day i'll try them again. but they'd have to sort out that midrange, it was so unpredictable.
