Headphoneus Supremus
Try playing Stevie Wonder's "Mary Wants To Be A Superwoman." If you question the Altone's bass after that (especially the first 15 seconds of the track) then probably these iems aren't for you. I'm doing burn-in right now with mine (aside from listening to them) but with 5 hours on them they sound great. Clarity is where these are at. I do hope the burn-in brings down the upper treble slightly, Stevie's harmonica on his early stuff is right at the edge of too much in the highest registers.
