More than 40 years ago this simple hearing protector, the world’s first foam ear plug, revolutionized hearing protection in the workplace and has remained to this day one of the most widely used earplugs in the world. The 3M E-A-R Classic Ear Plugs OCS1137 are constructed from slow-recovery, low-pressure foam. They fit snugly to create a noise barrier that helps protect hearing from loud sounds. These ear plugs are stiff enough when compressed to make fitting easy, yet soft enough to be comfortable in the ear for extended wear. Bright yellow color allows supervisors to conduct quick visual hearing protection compliance checks. Recommended applications include chipping, chiseling, drilling, furnace operations, grinding, heavy equipment operations, machining, pouring/casting, power fastening, riveting, sanding, sawing and welding. These earplugs are commonly used in the following industries: agriculture, automotive, chemicals, construction, general manufacturing, healthcare, oil and gas, and pharmaceuticals. These regular size earplugs comfortably fit most people. These ear plugs have a Noise Reduction Rating (NRR) of 29 dB, CSA Class AL. * These earplugs can be fit tested with the 3M E-A-Rfit Validation System. Moisture resistance helps maintain a consistent fit, even when humidity is present. Not only is noise present in our daily routines, but millions of Americans work in hazardous noise on a daily basis. Estimates from the National Institutes of Health suggest that approximately 15 percent of Americans (26 million people) between the ages of 20 and 69 have high frequency hearing loss due to exposure to noise at work or during leisure activities. Hearing loss due to noise is almost entirely preventable by consistent use of hearing protection. * Note: 3M strongly recommends fit testing of hearing protectors. Research suggests that many users will receive less noise reduction than indicated by the NRR due to variation in hearing protector fit, fitting skill, and motivation of the user. If the NRR is used, 3M recommends that it be reduced by 50% or in accordance with applicable regulations.

Why Use Hearing Protection?
Hearing loss due to noise is almost entirely preventable by judicious use of hearing protection. To find out which hearing protection products are best for you, try different devices from the wide variety available today. Be sure to carefully read the instructions — hearing protection must fit properly and be worn correctly to do the job.
Hearing protector effectiveness is specified by a Noise Reduction Rating (NRR), typically ranging from 15 to 35 decibels. In practice, the protection that normally can be achieved is about 10 to 20 decibels. The more carefully you fit and wear hearing protectors, the higher your protection will be.

Doing it right means doing it safely. That means choosing the right safety products before the project begins. With a full portfolio of personal protection and home safety products, 3M Safety Products are designed to help keep DIYers and professionals protected in and around the home.

I am a professional carpenter and as such I use a lot of ear plugs. This 3M slow release earplug is by far the most comfortable ear plug I’ve used with the best fit and noise reduction.

These are my go to earplugs to wear while I sleep, a habit I picked up when I traveled for work. They are soft and squishy and easy to put in. They don’t have a firm edge like some other brands do so they are comfortable to wear all night. They aren’t too long, which also makes them extra comfy. These are the superior ear plugs and this box is huge so I am stocked up!

These earplugs are slightly longer than the ones I’m used to. In a way, it makes them even more effective! Easier to remove as well. I’m happy I bought them!

For more than 15 years, I used to use another brand that had similar shape and material, but they recently changed material and those plugs no longer worked for me. It took me few month to try other ear plugs and see which ones worked for me. I finally found these ones. I like how they fit my ears. They may not feel soft before you put them in, but ones they are in, I do not feel them at all, there is no pressure, very good sound isolation, I could barely hear only very loud noises. I sleep well with these earplugs. I already bought it several times (200 packs) and I have no plans of changing. The only thing is I wish they didn't come in individual packaging (2 plugs per pack).

I've been using these earplugs for decades. I used to work in an industrial facility and let me tell you. THEY WORK. If your ear canals are a little wide and not too deep, you can't go wrong here. They can be reused a few times. I've introduced these plugs to some of my friends and now they're spoiled as well. If you're headed to a muisic concert, you can't beat 'em. All the great sound comes through with none of the head pounding noise. I use them when I go bowling and the house is full. BTW, clean your hands first.'Nuff said

Unlike the soft tapered ones you see advertised, these actually work to block out sound. They are harder to the touch, which is good because that means that after you scrunch them up and put them into your ears they will expand and stay hard enough that they don't fall out like with other ear plugs.I highly recommend these earplugs.They even do a good job of blocking out blaring music from the psycho Medusa gorgon next door who plays loud music just to annoy the neighbors.Get these, they work well.

After using this type of ear plugs for many years, I have come to rely on them in order to sleep. I would periodically get a multipack every so often, from a variety of retail sources including drug stores and online from Amazon. But somewhere in the last two years every retailer and manufacturer seems to have changed the material of their foam earplugs to a smoother foam texture or surface. The smoother plugs are uncomfortable to me and repeatedly slide out of my ears. I was in a panic that I might never be able to sleep peacefully again after numerous purchases that seemed like these, only to find they were the smoother new material. In desperation I bought this MULTIPACK (as in much bigger quantity than my usual purchases) for a reasonable price hoping they were the plugs I craved.I am thankful to God and 3-M that these were indeed the good kind. I now have at least a ten year supply, but that just makes me feel less anxiety about being able to find them. They work great and are all in convenient packs of pairs that I can easily grab on the go if staying overnight at a hotel or a friend’s.

These work as a great alternative to Flents earplugs, since they recently redesigned their plugs. They block out sounds just as well, are perfect for sleeping and long term use, and don't irritate ears if you leave them in. The only downside is that they don't return to their original shape very quickly or easily, and they are not skin color. Overall, I now consider these to be some of the most comfortable earplugs on the market!
