Anyone know if there's a special tactic I need to use, in order to take these things off without damaging anything? I think that there may be a pin or something I need to remove...thanks in advance!

You gotta pet him first.

Just don't pet him while he's eating!!!

You two are SOOO helpful...hahaha

Pretty much the same approach for most o-matter frames: a 'twist and pull' motion. I generally have the earstems about halfway open, then a sort of twisting motion down and away from the frame will pop the earstem off. Reverse motion to get them back in. I've never broken an earstem with this - but it never feels like they are made for constant swapping.

Thanks Oog. Just tried it and it worked like a charm! I was just scared to apply too much force before I found out if there was some sort of pin in there or not.
