If the eartips are removable, try a foam type. It may have to be replaced often from sweat though.

It all else fails, you can look at getting Etymotic ER2XR wired in ear monitors. They fit deep and shouldn't come out.

That's good design 👍

Are there vents for the bottom of the console?

Unfortunately I had no luck at all with ELAC support last year when trying to get a defective speaker replaced. They completely ghosted me, not even a single response.

They are Elac Debut B6.2 that I'm using near field at my desk. The left channel woofer is clearly internally damaged from shipping as the bracket is bent slightly, and the woofer makes buzzing noises from 40Hz to 2Khz. With music that is complex enough, I don't hear it. I still wish they would of done something. And the acoustic foam was completely misplaced and covering the port on both speakers, so I had to get my hand in there to fix that.
