Enjoy noise cancelation without bulk, batteries or electronics. This is the perfect hearing protection for situations where damaging noise creates the need for hearing protection to be quickly available and easy to put on and take off. Hear conversation without having to remove your hearing protection. The SG-31 is ideal for use around intense noise including power tools, outdoor equipment and firearms. Maximum protection provided by this lightweight device. Hearing damage will occur over gradually over time, so always use hearing protection in noisy environments. This product is tested to ANSI S3.19-1974 and is CE and CA tested and approved. How it Works Acoustic foam cuffs seal at the outer ear canal and the lightweight chambers act as an extension of the ear canal. Sound energy reaches the cuff and is directed away from the ear into the chamber. High decibel sound waves are dampened, refracted and cancelled. The chambers are tuned to create an even reduction in sound across all frequencies. Communication and Safety Are Key Hear the useful sounds in your noise environment. Conversation is possible without the need to remove your hearing protection. Hear shouts and warning signals more easily. Feel more aware and safe in your noise environment. The SG-31 is recommended for maximum protection.

Rated 3.7 out of 5 by 3 reviewers.
Rated 4.0 out of 5.0 by Excellent to use for loud concerts! volume. I could hear all of the tones of the music but at a volume that won't make me lose more hearing. Other earplugs that I tried were rated at lower decibels but muffled the high and mid range tones so much I didn't enjoy the music. These were great. Also used them with my vacuum cleaner and hedge clippers. With activity like that, I had trouble keeping the band on top of my head. However, I moved it under my chin and was able to use them that way. May 20, 2014
Rated 4.0 out of 5.0 by light weight, decent noise suppression These are light weight and do allow more normal conversation than ear plugs or muffs. Noise suppression was good. After an hour or so, they started to make my ears sore. I plan to use them on a regular basis. January 25, 2014
Rated 3.0 out of 5.0 by Would be great if I has bigger ear holes The product does do a decent job on reducing noise but they just do not fit in my ears as nicely as I would like. They are still better then nothing and not as hot as over the ear muff December 17, 2013
