Headphones

TLDR: Product recommendations please!

Purpose: for traveling on planes. Ambient /background plane noise doesn't bug me one bit. Ironically I find that noise cancelation headphones usually make the sounds of screaming kids worse; because it isolates all of the other background/white noise thus leaving only the screaming to hear.

I am not a sound engineer and this is way out of my expertise- just looking for go-to headphones that excel at blocking crying/shrieking pitched noises. I don't care if they serve zero other functions. Would not need the headphones for any other purpose - they would be just for plane travel.

For the sake of this post, let's say that money is not an issue.
