AZLA SednaEarfit Foamax

The AZLA SednaEarfit Foamax blocks the outside world better than any other tip I stock. The foam expands after you insert it, so less noise gets in and you can listen at a sane volume on a loud commute. The sound turns a little warmer, with thicker bass and a softer top end, and like all foam tips they're a consumable, so expect to replace them after a few months of daily use.
