...the Comply tips ok but no noise isolation!
And it gets oily.. its a sponge soaking in oil
Specifically it's memory foam; though I find (perhaps due to the large stem diameter of the X2) the portion of foam on the X2 comply buds a bit the miserable.
as for the ear oil soaking issue; it happens to most (I think Shure has some complys that have a layer of guard but their bore doesn't fit X2s) comply tips.
...the silicon tips kinda enlarged and would slip off the earphone...
Yah, happens to me too...I have lost both my L-size already
...BBGo2 has a protrusion to prevent the eartips from slipping out...
Very interested to see this portion.
...Can anyone who has the X2 take out the silicon ear tips and take a pic of the bore?
Since I've lost my main pair (the L size ones) of X2 eartips, I can provide you a photo of the stem now, as well as my current eartip replacement...I suspect due to the weird tapering at the bore of my current eartip, it actually prevents a full dislodge when I extract the earphones out of my bag & pocket:
Truth to be told, eartip slipping off its stem happens to me when I was using some other brand of earphones.
& it's always one of the sides (unsure if it's always the same side)...
