Agree with @user34.
Another way to make sure if you get the most from hearing aids is doing Real Ear Measurement with them (procedure which includes insertion ~1mm diameter very soft plastic probe microphone with ending placed near the eardrum).
Which hearing aids do you have? What diameter of vents?
I don’t know about your financial possibilities but perhaps consider at least trialing the new hearing aids like Phonak Infinio Sphere 70 or 90, Starkey Edge AI or newer Omega AI, Oticon Intent or wait to new generation which should be released this week or February 2026 at the latest… etc.
