Got tired of those 50cents orange-foam earplugs when rehearsing... they cut the frequencies so much. So tonight I stumbled on these "Full Frequency Earplugs" by PlanetWave and I can't wait to use them this week-end. It sells around 20$ I know there are better alternatives (my brother paid something like 200$ after talking to an audiologist and got something specially shaped to his ears) But yeah.. for 10 times cheaper I think it's cool. Anyone used these ? Do you even protect your ears ?
