Unfortunately, earplugs often in situations such as noise in discotheken are not worn because they can be seen ...

Now, EAR has developed a really great product. The first earplug with noise filters that is almost invisible.

Three soft blades nestle gently in the earcanal. The wearing is very pleasant.

The ClearEAR earplugs have a short rod which is hardly out of the ear canal. They are not only transparent but also disappear even in small ear canals almost entirely.

The package brings in addition to the two ear plugs or a small case that fits in your pocket.

The attenuation value is 20dB SNR (What is this?)

Thus the earplugs just lower down the noise until it is harmless. Language is not well understood.
