Sorry to hear about your having a stroke. Wishing you the best in acute rehab.

The only way to test these devices is to use them in all situations where you need the kind of support they provide. With hearing aids and assistive listening device products you should have a trial period for testing. If they don't work as well as hoped you can return them. The key is to do that testing. Happy to know your son is helping your husband. Do get well yourself!
