Kurzbeschreibung
Surefire Sonic Defender Plus EP4 Medium
Material
hypoallergenes Polymer
EP4 Sonic Defenders Plus offer significant protection against continuous noise (such as aircraft or tank engines) when the filter caps are plugged in / unplugged. When the filter caps are open, they also protect against loud impulse noise, but allow safe noises (such as commands) through. The louder the impulse sound, the more it is insulated when the filter caps are open. Made of hypoallergenic polymer, the EP4 with the patented EarLock® retaining clip sits comfortably and securely all day.
The EP4 have the same properties as EP3, but with a wider flange and are therefore better suited for larger ear canals.
