I have read hundreds of reviews and I am still so confused. I need something that will block out screaming babies on airplanes. It needs to be small, so either earbuds or foldable ear muffs. Under $300. Compatible with an older iPhone SE, iOS 14.8.1. Comfortable.

It does NOT need to be wireless, produce quality music, have a microphone or phone capability, waterproof, or anything else. Just block out babies...and ok, those industrial strength lawn mowers.

Can anyone point me in the right direction?
