They seem to get a bit slippery and I have to push them back in.
They do have the wing on them and it helps put I still amhave a need to push them in as they seem to get lose. Especially when I run.
I suggest looking and talk ming to your workout partner's.

they do work, if you dont sweat too much. Good sound, for the office environment or around the house or mowing the yard.. not for running.
