I'm glad you enjoy them. I bought Auvio tips a couple of years ago when I got the ATH-IM70. A lot of people on a particular head-fi thread said they were a good fit and sound for that IEM. Looking through one of my junk drawers, I came across the packaging and remembered them then just decided to search for them randomly if they were still around. I paid like $7 or $8 then for 2 pairs originally.
