My Etymotic ER-6 earphones are shot...I really beat 'em up good over the last few years. I'm consdering trying out the UE/M-Audio offering, but only if they'll work with my custom molds. (I'm spoiled by the custom molds and don't find any of the stock earphones comfortable enough now that I'm accustomed to custom.) The molds have a button hole into which the ER-9/15/25 filters fit. My old ER-6s fit the button hole, using an adapter. So...the questions...
<1> Do the Super.fi 5 Pro (or M-Audio equivalent) fit the ER-9/15/25 button hole
<2> If so, do the earphones still sound good?
I asked UE customer service, and they didn't really answer the question...simply said they don't recommend it, as the custom molds muffle the sound. Don't know if it's because they don't fit properly, or if they fit but the molds' architecture doesn't allow proper piping of the output, or what. Besides, they have a vested interest in trying to talk me into their own custom molded options, so I'm not sure I trust them.
