hahaha very sorry, my english is very bad
now i also use the small zipper case, but if i put it into my bag with everything inside, im affraid if my other stuffs could damage the iem
even i know that acs's durrabillity is very good since it made from silicone
i also have a otterbox iem case (the small one)
but im affraid it could damage the cable when i close the case, cable easy stuck between "case mouth"
is there any other opinion?
