Blox Cylindrical Foam Earplugs perfectly fit into the ear canal so that it is easy to keep the earplug secured in the ear.
With their standard size, these plugs are designed to adapt to all the ear canals. They offer a very performant attenuation of sound (-28 db) and an excellent held in the ear, thus preventing from losing the earplug during the night.
The noise reduction is very good, but will not turn off the outside world (alarm clock, alarm).
Box of 4 pairs.
