Have used the 4s for atleast 7years.They are great especially for airtravel and exercise.For me they only work with the white "rubber" fittings.They do clog up at times and you have to replace the green filters.They are not as good as the STAX speaker phones or the sannheiser 600 but these earphones are realy only for home use.
etymotic 4P earphones
I just bought these for the ipod....dont have the ipod yet, but used them with portable Cd players. They sound very "tinny" - elevated high frequencies? Not natural at all. Do the Shure ipod earbuds/ phones sound better? Do the etymotics sound different with ipods? Should I try the other versions of these phones?
