Hey Head-Fi, I was wondering if it would be worth me dropping £15 on a 3-pack of T-400 buds. I've heard that they would help with comfort and seal, though do they have a big effect? At the moment I am using the medium size stock biflange tips on my RE-ZERO IEMs, which are pretty good but after about 20-30 mins of wearing my ears become irritated with them and they become uncomfortable and just make me want to take them out (some sort of sensitive skin reaction?).
I like to wear the tips quite deep, so would the T-400s be able to be worn deep also, without coming off inside my ears?
