i wouldnt say the sound completely changes, like what i meant was that before the klipschs were siblant/ harsh but the comply foam (its not hte foam its the inner core material) that took the edge off the top end
the i can still hear the top end of the klipschs (it didn't chop it off) lol its still its like if i can make an example if before i was driving at 60km/h (im canadian) and the comply foam is like the brake (it pulled it back like down to like 50km/h)
once again it didnt kill the entire top end, the control on the klipschs were the same (still out of control treble) but its a little more pleasant to listen to
but if you got the mk1 thats know to sound a bit siblant, it should be okay.
maybe iems aren't for you, but what i do know is that complys made iems immensely comfortable (the klipsch silicone ovals were very comfortable, for silicones) comply just took it to a whole other level
this is just imooo afterall, maybe the its edges on the gr07 housing that making it uncomfortable to you, not the part thats inside your ear canal
still debating on whether or not to save up for the gr07 or just get the gr06 right now, (or wait for the new lineup)
Any thoughts?????
