Thanks for the part number of the original sleeve, as I find those to be superior in every way to all else that I've tried with the 10's and was a bit concerned about what I would use if, and ever, they went bad.
Now, I must go in search of...
Cheers.
You are welcomed AudioDwebe. Seeing as you are located in North America, I'm not very sure if the local distributors at your local region have these Audio-technica accessories in stock. If you do have trouble locating them yourself, I would suggest you to just grab them from Bluetin online, as they do ship internationally and they get their stocks straight from JP, with their office warehouse located there so I suppose you won't have to wait too long for them to confirm shipment to you, after placing your orders. The ER-CK9 stock silicone tips replacement box do come in 3 pairs in either S, M or L size, you may have to indicate your preferred size to them under the comment box after placing your order, since they do not sell these with all 3 sizes included like what you get bundled with your CK10 out of the box.
Hrm, I see reference to people using the Shure triple flanges. I have a pair of these, and the stalk diameter (and inner hole) looked woefully too small to fit on the CK10. Do people force them? Are the Ety's or Monsters a larger diameter stalk, or the same as the Shure?
No personal experience with Shure tri-flanges myself. Etymotic Research's tri-flange stalk diameter is indeed alittle small compared to Monster tri-flanges (which fits just nicely on both CK10/CK100), but according to my own experience and what RADI0HEAD had wrote, its true that the Etymotic tri-flanges are pretty stretch-able to fit the nozzle tube without issues, at least there's no need to do any form of modding unlike with Shure Olive foamies as far as concerned.
