Looks like I've almost worn out my current foam tips that came with my etys, which is unfortunate, because I'm residing in a place with the slowest postal service ever - Russia.
Surprisingly I got my hands on some tips for the ER4 in a local store. Actually they are supposed to be Etymotics own foam tips - labeled ER4-14F. I'm a bit worried - Etymotics website has got no notice of them (only ER38-14F), the foam is very soft and expands in a matter of seconds, which gives me a loose fit. And another thing: the canal is very stiff and small - I managed to force the IEM in, but I'm afraid to damage my earphones.
Can anyone tell me, if its ok to use them? Or should I use my old ones for a couple of weeks till my Complys arrive?
