Do you still have your hearing intact? Good, let's keep it that way. When your hobbies include loud blasts from guns or a drum set, shouting kids, et cetera, you better take care of those ears of yours. If you're on a tight budget, here is what you do: Get some slightly used Peltors from the British Army! One-off lot.
In addition to the mega-super-war-high-tech-active-navy-seal-electronic hearing protectors, Peltor also makes basic model ones. These are British army surplus hearing protectors, and the models usually vary a bit in surplus lots – we are not going to do any sorting, they all function the same and serve their purpose well.
The latest lot are all slim, green ones. Perfect for e.g. rifle stuff.
These Peltors are used but in perfectly serviceable condition. If you need good and inexpensive hearing protection, this is it!
