I use these for band practice. The studio charges £1 for a pair of disposable ear plugs, but i bought these and you get 2 pairs for £1.50 and they are re-usable. Not only that but they come in a little plastic case. Its a no brainer, these are great value for money, i would definitely recommend them. The only negative thing i could say is that they dont also stay in my ear properly, but i have that problem with all earplugs.
