no, the ACS sleeves are different, that is why they have ones for different models listed on their site. the ACS ones partially enclose the body of the IEM itself, rather than simply going on the stem. this has the advantage of making them somewhat more low-profile, but also means that they will not work well; if at all with other IEMs.

on another note, the lady on the ACS line told me i have to get "full chonca to the second base", what is second base? |
well second base means something else here in OZ
I dont know if you want to go to 'second base' with your audiologist or not, that is a matter of personal taste
. but seriously, I would just write it down word for word and bring it with you to the audiologist, so they can make sense of it, but a full concha means the impression material must fill the entire space in your ear, the ACS are different to the westoine as I said; the 'second base' is likely the second bend in your canal. when I got my impressions for my UM56 and also others for my JH13, both times I specified a full ear impression (as recommended by westone and Jerry Harvey), past the second bend. as it turned out, with my excellent impressions for JH13, I went just past the third bend. they will not need them quite that far for the ACS or westone sleeves though, I wanted extra deep fitting customs, so I asked my audiologist to go as deep as he thought was safe
