It can also work the other way- if you need budget noise isolation- get foam earplugs, and over ear headphones, turn the music up while simultaneously not hearing anything but it. Saved my hearing while riding motorcycles. Cheap helmet speakers sound pretty good with the volume cranked up and ear protection in- while it blocks out the dangerous wind noise.
1. Get any in-ear earbuds (for noise even cheapy ones are fine, for music pick whatever type you like).
2. Get the foam tips to fit them: https://www.complyfoam.com/products/t-series/
3. Put some hearing-protection ear-muffs on top
A tiny amount of noise will make all other sounds disappear at this point.
