Low Profile Custom Communication Earplugs (LPCCE) (PN 05-016020) Our low-profile Custom Communication Earplugs (LPCCE), are a custom molded earplug alternative to generic foam and plastic tips used on the ArgonautTM Communication earplugs (PN 05-016017), Aegisound's stereo communication earplugs (PN's 05-016025) and C15 models (sold separately by Communication & Ear Protection, Inc.). These digitally manufactured custom earplugs provide consistent fit, fast removal and insertion, and are resistant to salt-fog, fungus, jet fuel, hydraulic fulid and other Military specified chemicals. They may be cleaned with soap and water. Because Aegisound saves digital earplug files, identical replacement custom earplugs may be reordered with a discount. The LPCCE comes with a passive tether (PN 05-016038) so that the earplugs may be worn as a hearing protector when use with communications earplugs is not required.
