EP4 Sonic Defenders® Plus protect your hearing without interfering with your ability to hear routine sounds or conversations. Their triple-flanged stem design fits larger ear canals and provides a Noise Reduction Rating (NRR) of 24dB. 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. EP4s include attached filter caps, which can be inserted for additional protection and blocking out lower-level noise, like that heard on a plane, where hearing ambient sounds or conversations isn't critical. Right/left color-coded Sonic Defenders Plus 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, adjustable triple-flanged stems provide secure seals in the ear canals. A low-profile design means EP4s can be worn while wearing a helmet or mask, or while using a phone or headset. Available in clear, black, or orange.
Comfortable EP4 Sonic Defenders Plus also serve as earpieces for compatible radio communication systems* simply by removing the noise-reducing filter and attaching the earpiece to the system. NOTE: EP4 earpiece no longer provides hearing protection once the noise-reducing filter has been removed.
EP4s are available in small (S), medium (M), and large (L). Proper size is based on the dimensions of your ear's concha bowl. Size "medium" fits most people. For those with smaller (in diameter) ear canals, the two-flange stem of our EP3 Sonic Defenders may provide a better fit than the EP4's three-flange stem.

These are normal earplugs with a slightly more anatomical design. They fit perfectly in my ear. I don't know about you, because our ears are unique. This plug has a sliding hole that you can open or close to adjust the amount of attenuation. I keep these closed and the sound of the earmuffs at full volume. This way I can also hear the track commands without endangering my hearing. Or what little is left of it. These come with a handy storage case. They also came with some kind of string to connect them if you were to use these alone to protect your hearing. I threw it in the trash. After all, these are expensive compared to regular plugs, but they are also better. Double hearing protection is a joy with these.

At least it fits my ear really well. Damping can be adjusted by changing the installation depth without fear of the plug falling. I use both EP3 and EP4 versions, I vary them depending on the conditions. Both also work excellently as earpieces for air tube headphones, so they are more versatile than regular earplugs. I recommend!

Sorry didn’t hear you had my ear defence in! Does what is advertised .. Ask about the different sizes of ear piece L/M/S, they only advertise about the size of ear plugs..
