got these foam tips (wax guard) for my SE215. Started noticing wax build up in the IEM from sweating in gym
Tx-100 - Comply
I noticed they are more softer and comfortable than the given Shure foam tips. also has wax guard which is a screen that prevents the wax from gettin inside the IEM. Good investment to protect your IEM
