EP3 Sonic Defenders - Ear Plugs

In fact, this gadget was developed for the military, but in civilian life, it obviously can also be useful. EP3 Sonic Defenders - earplugs that block the ear if someone snores heavily or shoots a grenade launcher too often. The main thing is that the sound should be louder than 80 dB, all that is quieter the acoustic filter of the Hocks Noise Braker allows you to hear. However, if you still want silence, you can use a special valve and “mute the sound” altogether.

Sold earplugs here for a ridiculous $ 13. True, there are some problems with delivery.
