I know what you mean. I received my JH 16s on 12/24 and sent them back a few days later due to a bad fit.
The canal are too long and they stick out. What caught my attention is that the top of earpiece is really thick similar to yours.
Clearly, JH didn't care about sending out a quality product. So far I'm disappointed and not sure I would buy another pair from JH.
As long as it does not have strength issue like my Unique Melody.
I'm totally fine with it. Since when its in your ears nothing else matter. (besides bad fit)
