I carry silicone putty ear plugs with me pretty much all the time.

They are very squishy and I can place then in my ear and depending on how thick I make them, they have varying levels of blocking out sound. Super useful if I want extra blocking or just a little light blocking so I can still hear things around me, but dampened.

They have been a life changer for me. The best kind I've found are Mack's. Maybe they would help you too.

Ahh I can't stand that pressure feeling, makes me take them out instantly!!
