They do, but they do not muscle in on the other sounds when they aren't needed.
How does the KC06A compare with the FX850?
Don't have them long enough to compare but bass end, the FX850 still wins, both in amount and quality.
Well that's just weird, just now heard that burn-in deteriorates an IEM's performance.
I heard the shimmer of cymbals becomes more defined around the 400 hour mark of burn-in.
I mean you were the first guy I've found confirming it, so I'm not alone then
lolz........ thats y we live in a brick haus.
My 850 is lost somewhere in a japanese warehouse...humphffff.
