EP7 Sonic Defenders Ultra protect your hearing without interfering with your ability to hear routine sounds or conversations. Their foam-tipped stem design, featuring soft memory-foam Comply™ Canal Tips, fits most people and provides a Noise Reduction Rating (NRR) of 28dB. Sounds, at safe levels, are allowed to pass through into the ear canal, while potentially harmful noises (above 85dB) are reduced via a proprietary design that incorporates a special noise-reducing filter. EP7s include attached filter caps, which can be inserted for additional protection and blocking out lower-level noise, like that heard on a plane, in situations where hearing ambient sounds or conversations isn't critical. Right/left color-coded Sonic Defenders Ultra are made from a soft but durable, hypoallergenic polymer that provides all-day comfort and an extended product life (up to 6+ months, depending on usage and care). Their patented EarLock® retention rings lock the earplugs in place, while soft foam-tipped stems provide secure seals in the ear canals. And their low-profile design means they can be worn while wearing a helmet or mask, or while using a phone or headset. Available in clear, black, or orange.
Comfortable EP7 Sonic Defenders Ultra also serve as earpieces for compatible radio communication systems* simply by removing the noise-reducing filter and attaching the earpiece to the system.

NRR 28
An NRR of 28 means that the hearing protection is estimated to reduce noise levels by an average of 28 decibels across various frequencies.
'NRR' in hearing protection stands for 'Noise Reduction Rating,' which is a single value used to indicate the average level of noise reduction a hearing protection device provides across different frequencies, essentially telling you how much sound attenuation the earplugs or earmuffs will offer when worn correctly; the higher the NRR value, the greater the noise reduction level is considered to be.
NRR is primarily used as a rating system in North America, while Europe often uses 'SNR' (Single Number Rating) and Australia/New Zealand use 'SLC80'; which both differ slightly in calculation.
