I have found that ACS in the UK will do
custom sleeves for my Westone UM2 at a reasonable price including getting the impressions taken.made. This is obviously a lot easier than sending impressions across to the US and avoids any hassle with customs charges etc.
Has anyone had any experience with them or actually seen them in person. It's hard to tell from the web site what they would be like as the sleeves are alos done for Ipod type buds as well.
I've emailed for more details but would love to hear from any users of them here.
The reason for the custom moulds is to get that little bit extra clarity & comfort over flanges.

PS If I get more details I'll post them here for others to see.
