Extended isolation for Shure E5c

Feeling cheated that the E5's don't provide quite the level of isolation that the Etymotic ER-4P/S does? Buy a bag of the Etymotic ER-6i/Etycom tips and seat them fully onto the E5c. Works a treat... although it will make them nearly as uncomfortable as the Etymotics in the process. Works on the Shure E3c as well.
