The American company Otis Defense protects hearing not only with active and passive headphones, but also in a much simpler way - earplugs. They are simple, but highly effective. They are very suitable for use at the shooting range, in the workshop, in the garage or even in the garden.
The practical packaging in a transparent bottle contains a total of 50 pairs of disposable foam earplugs. Just put this pack in your shooting bag, which won't weigh you down too much. And as a bonus, you get a waterproof pack for two plugs with a key ring, which you can take with you really everywhere. The plugs reduce the sounds around you by up to 33 dB (NRR = Noise Reduction Rating).
