Hearing protection.

I just wear earmuffs, and sing to myself out loud. It has the added benefit of making people avoid me.

Just remember, IF you have tinnitus, be very careful. With any type of headphones, pods....whatever, if you listen to music much above the level of your tinnitus, you'll hurt your hearing even further. It's a catch 22.
^^This. The wife keeps harping at me to wear my hearing aids more regularly, but has a hard time understanding this. When the tinnitus gets bad (mine varies from "crickets chirping" to an F-16 on full afterburner) I just throw them back in the drawer. I have had some relief with different devices utilizing white noise, but nothing consistent. After 40 years of this crap, I really miss good old fashioned silence.
