Need ANC headphones for walking

I would love to walk on the treadmill more. However I cannot stand the sound and it’s so distracting. I wanted to purchase over ear headphones for this issue because ear buds don’t fit me (they also always fall out because I have an ear wax problem).

But I can’t seem to find any that I could just walk in. I keep reading you shouldn’t use them in the gym. I don’t plan on working out with these headphones. But I would like to walk around an hour with them on. I was eyeing the Bose QC Ultra but now idk.
