Yes, you can buy in-ear generic meshes. Please measure size. Not sure if it's 3 or 4mm size. I've replaced both metal meshes, as they got loose after couple of years of using the PowerBeats Pro. The generic meshes you can find will work. Make sure they have adhesive. Here's an example link to an Aliexpress ... bot sure if it's allowed to post that link. But you can find them in any sizes and it works. https://de.aliexpress.com/item/100500414...-262a-4227-a9d2-707c22ccd856&algo_exp_id=b74a7f1a-262a-4227-a9d2-707c22ccd856-0&pdp_npi=4@dis!EUR!0.77!0.6!!!0.82!!@21...

The "Blue" stuff is Loctite and has nothing to do with "Anti-Tamper"-Measuremts.

What sort of experts are you? ;)
