3M E-A-R Earcap earplugs with a stem

Earplugs connected by a solid stem. They can be placed around the neck when they are not in use, so they are ideal for sporadic use, e.g. for workers who often enter and exit the facility. They are lightweight and create minimum pressure on the ear because they are placed in the entrance of the ear canal (no deep insertion). They can also be worn under the chin. SNR is 23 dB. EN 352-2
