You can't tell but the tip of the plug came off when it got yanked by accident. I couldn't tell if it was broken off or it's a separate piece. I pushed it back in by hand and there's a small space between the black part and the base of the tip. It won't go in any further and I don't want to force it in anymore by using a pliers or any other tool. When I plug it in to have a listen, it sounds perfectly fine. I cannot tell any difference in sound before I broke it and the tip seems to stay in place. I tried pulling it out without using too much force and it won't come out. I am wondering if I should fix this and where I could get it fixed or just leave it since it's working fine. It actually bugs me that I can see the little gap since the CK10's are my favorite earphones.
