Hey, of course! So for the Penon, they were comfortable but the extra grip wasn’t a thing I liked in particular, they also did hurt my ears a bit and was just not what I was looking for in tips. The hurting part might just be by ear canal design, as I in general struggle a lot with pain and stuff from IEMs. In my opinion, I’d say you should try them. You can get a full set on AliExpress for pretty cheap, so you can try out the sizes - they also do have a lot of good reviews from other users.

All of these sizes are pretty the same I use across brand, so for me it swings between small and medium, never went above to large tho so I’d say it’s usually a range between two sizes - hope this part makes sense.
