Bluetooth earphones keep activating Siri even if disabled

I recently bought earfun air pro Bluetooth earphones. They’re great, except for one thing: they randomly activate Siri when my phone is locked. The sound is very loud so I have to take off the buds quick so the bip doesn’t destroy my ears. I tried disabling Siri in my phone’s setting, but it doesn’t work. I already made 2 pocket calls today, it’s very frustrating.

do you know how I could permanently disable Siri or any voice command? I don’t use such features anyway.

thanks a lot,
