AZLA SednaEarfit XELASTEC II

The AZLA SednaEarfit XELASTEC II warms up and moulds to your ear in about a minute, giving the most complete seal of any tip I stock. That seal is where deep bass comes from and why voices sound closer and more solid, so it's the first tip I try when a set sounds thinner than it should. It also holds firmly, so IEMs that creep loose while you walk stay put.
