I got my IE 80 a month ago and it was perfect so far except the tips...the stock tips does not fit well and the isolation seems to be a problem to me.
So I bought medium size TX-500 Comply foam tips from Amazon.ca(3 pairs package), I checked the comply foam website and it confirmed that the
tip should fit ie80. But when I got these tips today, I found it is impossible to insert the nozzle into the comply tips. The problem I see is the wax-guard built in the tips seems to be very very solid and I cannot push the nozzle in. I can not try it harder coz I am afraid I will destroy the nozzle in that way ....
