Heres some imput for comply.
I use to use comply tips with my TF10 Pro. and on avarage each set of tips use to last 10-12 days.
at 15 euros for 3 pairs that gets mightly expencive.
Use better foam.
This might sound like an aggresive post but it was really annoying that up untill a few months ago comply had the only decent wide nuzzle foam tip.
the foam Monster supertips arent quite there yet but they get decent comfort and beat the complys in longevity by a mile for all of us with Sennheisers or older UE earphones.
