Yeah I did mate, I replaced them with a pair which are the same, no apologies from the sop though, they look at you as if you've done it! Terrible customer service.
Anyway I have to say the results are remarkable. I put the ipod on random and it played, of all things, Rock On by David Essex - it sounded like a totally new record that I'd never heard before, just couldn't believe the hidden detail it was bringing out. Playing Dub nearly takes your head off with the bass. So as a sceptic, I have to say you really do appear to get what you pay for.
