ABOUT THIS ITEM

ER-20 earplugs are different - they'll protect your hearing without spoiling your enjoyment of music and reduce the risk of serious hearing damage later on. They use a patented, revolutionary filter system that drops the volume but retains all the fidelity and keeps you in the mix. They are ideal for use in most situations where noise is dangerous. ACS ER-20's are re-useable hearing protectors that protect the ear against excessive ambient noise. Due to the special filter, the fidelity of the original sound remains and speech intelligility is hardly affected.
