helps w/ the high speed

I purchased these last year after a friend of mine told me that his hearing was starting to go. I am a dentist and the highspeed drill's noise is constant all day and can do damage over the long run. Knowing that I have many more years to go, I'm now using the Defenders and love them. So is my assistant. They definitely block out the high pitch soundwaves from the drill. I would recommend them in a heartbeat to any healthcare worker who's around constant noise.

EP5 work

I was looking for ear protection while motorcycle riding. I tried foam plugs, some sort of wax plugs,and a product that you mixed and let harden in your ear. They all had their faults.Right now these are working great-easy to insert and more importantly they stay in when riding.

Setting the standard

These ear protection/plugs make it easy to wear them all day, and can be partially inserted in the ear therefore allowing even faint sounds to pass. When full protection is needed, they can quickly be pushed into the ear canal even while wearing gloves, this can be reversed by just tugging on the conch bowl part of the ear thus allowing continuous use without getting dirt on the earplugs. To a construction worker, the EP5/EP4 are essential. We patiently await the rerelease of the radio communication sound tube attachment.

I wear these plugs under my flight helmet. They are good attenuating the noise while still allowing clear coms. They are very comfortable but more of a cool gadget and kind of expensive.

Great Product

I bought these for the range, but I've been using them for just about all my ear pro needs. These are pretty amazing when used riding a motorcycle, the in ear design really reduces the wind noise you get with all other plugs.

I bought these ear plugs to use in a high noise enviroment they are not intutive to use and offer no more decible reduction than the foam plugs you can buy at any drug store- a waste of money

Great Hearing Protection

I am a Police Officer and Firearms Instructor and I have used several variations of Surefire hearing protection or radio ear pieces for several years now. I don't like the over the head earmuff style when shooting and these are a great alternative. They are very comfortable and provide adequate protection for small arms fire. I like that I can wear a hat and protective glasses comfortably while still getting great hearing protection from these earplugs.

EP5 Sonic Defenders

Excellent and convient ear protection. I wish I had more pairs. They are comfortable to wear and when not in use they hang around the neck or can be attached to the hat.
Surefire put out a great product that was needed and keep it priced reasonably low. Keep up the good work!

Affordable, reusable "full-block" EP5 Sonic Defenders® Max utilize a soft, adjustable, triple-flanged stem to seal the ear canal and block out potentially harmful sounds, providing an impressive Noise Reduction Rating (NRR) of 26dB. EP5s are an excellent choice for industrial, tactical, and general applications where maximum protection against continual noise levels is desired and the ability to hear ambient sounds or conversations is not a priority.* EP5s are made from soft but durable, hypoallergenic polymer for 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 allows EP5s to be worn with a mask, helmet, or supplemental hearing muffs, as well as makes them more comfortable for sleeping. EP5s come in three sizes—small, medium, and large—with mediums fitting most adults.

Sonic Defenders Max are available in clear, black, or orange and are sold as a single left/right set or in a box containing 25 sets. Each set is packaged in a convenient carry case and includes a polymer lanyard.

*For hearing protection with the ability to hear lower-level sounds and conversations, use filtered EP3 Sonic Defenders or EP4 Sonic Defenders.
