When I first saw these, I thought: I gotta have them. So I bought them. My friends laugh when they see them, but I love them.

the o-ring groove is deep like everyone has stated, which can make these plugs a little fussy to get in and out. the image is huge and you can easily tell what it is. I've gotten lots of compliments on them so far.

A bit uncomfortable. My ears got a bit stuck around the deep groove for the O-Ring in the back. Even while they're in, they're not that comfy. I'll give them another shot later.
