This actually got me thinking whether the B40 could be compatible with mx500/mx760 drivers… If it's not just glue or extra thick plastic on the cover but they actually modified the shell to snap on bigger front covers then it might be possible. I haven't got any real support from the sellers so far so basically wasted 20bucks on empty shells and mediocre cables.. I might just put on a dispute and disassemble these buds, at least we get to see what's inside lol. If I ever get some kind of refund I'll just buy some speakers from it as replacement, it would be fun if this b40 could actually accept something like an emx500 or the speakers I have in my mx760.Thanks for checking. I find the smaller & shallower SR2 more comfortable.
