What headsets are good for a particular person tends to be, well, personal. Age doesn't really have a lot to do with it. I'm eligible for Social Security and I love my AirPod Pros (2nd gen). I did have to get third-party ear tips because the ones from Apple don't fit my ears and they would fall out. Ears are very unique.
AirPods are far easier to use than most Bluetooth headsets, in my opinion. Other than remembering to charge the, you don't have to do anything but pop them in your ears and they work.
Anything you buy from Apple has a 14-day return window. You could certainly buy the headphones and test them out. If the person you buy them for doesn't like them, you can return the.
Also, have you asked this "elder" what they think? Many of us know what kind of technology we like.
