I’ve tried foam earplugs, but those are impossible to use socially as everything’s too muddy. Also they’d end up sliding out eventually.
I eventually bought audiophile grade earplugs and they are FANTASTIC but the flange tips irritate my ears so bad.
I know circumaural headphones work great, but people have a harder time understanding I’m just using them as a filter to even hear them.
How much do you want to spend? High end Shure canal phones with foam tips are pretty good. I’ve had a set of Shure SE525s for 18 years. They were about 500 bucks.
