Just came accross this product from Westone and thought it is very interesting and could be useful for those who love their hi-fi buds but want a more comfortable fit/increased isolation...

Not sure about these, but no matter what I have tried (I recently tried the Comply ear bud conversion product, with poor results) to turn ear buds into IEMs/canalphones, it doesn't work. I could be wrong on this product, but I doubt it. Ear buds are ear buds for a reason. Even the Yuin OK lineup, which are designed as convertible ear buds, lose their great SQ when using the canalphone converson option. At least that's whay I found (as did reviewers of the Yuin OK2s and OK1s).

Again, this might work. But it would cost a lot to find out.
