For me it’s the notification light you used to find on older phones, was particularly good to know if your phone was charged without picking it up
I have the Samsung Galaxy Buds Plus and their app has an option to disable touches, so that’s what I do, because I’m the same as you. I bought them used and have been using them on a daily basis for at least three years and they’re still working well. Might be something to look into. I hope you find something that works for you!
