I was fiddling with tips in my GR07 just now and I noticed that the right shell strain relief (small black plastic piece between the shell body and the cable, where the cable enters the shell) is a bit loose, more than the one on the left side. I remember reading about others here that had this problem a long time ago, and I think the advisable action is to use a bit of superglue to secure it back in it's place, before bigger problems may come from there, right?
Yeah, be careful. That happened with my very first GR07, and I think I used too much glue. Over time the glue must have seeped into the driver.
