I was wondering if it could be used for IE600 until it arrived, but if the part to be applied to the ear is already thick, the hook will not fit in the first place. This is where the photos alone were not well understood. If the cable is thick, it may not be possible to use it in the first place, so it seems that you need to be careful. So I tried using it for the antimal Markii Sure hanging. In my case, the ear holes were large, and if I put them on as the E -earphone staff reviewed, I couldn't do the same with the force applied from the cable. However, it is possible with this item. It's okay to hang it. It doesn't seem to be inferior between Typea and Typeb, so I buy both, so I use a hook that can be fixed to the balance cable that I often use, and a hook that can be easily removed on the unbalanced cable that occasionally uses. I am.
