Best Earplug on the Market!
When you combine supremely soft comfort, with eye-catching colors, AND offer incredible noise reduction rating of 33 decibels you have what in my opinion is the finest value in earplugs on the market. Could you pay more and get better protection in a custom molded plug? Probably. But for all-around effectiveness and ease of use and comfort these are tops! Made in the USA, and worth every penny. Almost as iconic as the Sharpie, these are one of those staples that should adorn every shooting range or factory floor or workshop.

Sooo quiet
These are the only ear plugs I can have in my ears all night or all dayI use these for my street/ track bikes and also at night when the ambient noise level is loud.They're very comfortable in the ear and after 8 years of continuous in ear use my ears feel good.Great for sleeping as they don't protrude far enough to be uncomfortable while on the pillow.Great product.

I am now on my 2nd box of these earplugs. They are the only ones for me after trying many, many types and models of earplugs. I live in an apartment with less than adequate sound proofing on a busy main street, a block away from a train line with LOUD whistles day and night. I am also near 2 major hospitals. Compounding all of this I have medical disorders which make pain and insomnia a regular nightly issue. Ear Plugs are a MUST. If you sleep on your back I suppose you have more options. As a preferred side-sleeper most of the models I tried were painful over any length of time or simply couldn't cut out the noise level. I've been using this brand now for 5 years and they are a Godsend. They don't work as well as the Bose noise cancelling earphones, but I'm also not wired to my laptop getting strangled. They are very comfortable though for nightly wear, easy to put in, and considerably mute the worst of the trains and sirens. I find that I can stream movies on my laptop, and if the volume is full on I can still quietly hear the movie (but will need CC to understand. They definitely will block out neighbors, most children outside, muffle fireworks, and motorcycles. On occasion, due to dry ears I have to put a drop or two of olive/ coconut oil in the ear canal to prevent itching. I don't imagine this will be necessary for all users. Overall, these have kept me sane in a noisy world. HIGHLY RECOMMEND!

The best earplugs on the market
I am obsessed with these earplugs. They are literally the only ones I’ve ever found that I can roll small enough to fit securely in my ear and actually block a decent amount of noise. My husband’s snoring is out of control, and these allow me to finally sleep.I’ve bought countless boxes of these, and my most recent has a weird issue where some of the plugs are more dense than others, so it’s harder to roll them as small as I want. I didn’t knock a star off because, even with that issue, they’re still your best bet.

Comfortable, effective and long lasting
Easy to insert, stay in place and quiet during sleep. This spark plug style works much better in blocking noise.

Best ear plugs on the market
I’ve used these at work for decades. Best on the market. Purchased for Motorcycle use and yard maintenance. Also prefect for travel at hotels to shut out the late night arrivals by the party crowd.

Most sets good
Most of the sets of plugs in the batch were good. Some were just impossible to get set, like the foam had changed. Besides that these plugs worked great.

I we’re hearing protection a lot, whether working with power equipment, power tools, or on the range, I’m using hearing protection at least two or three times a week.I was first introduced to spark plugs our customer site, It is one of several brands they have throughout their plants; they have three or four different types so that employees can constantly choose the ones that work best for them. From the first time I use them, I was very happy with their comfort and the amount of noise a reduced.I would absolutely recommend these for anybody in need of hearing protection, they just nail it in all categories. I’ve had pairs last me several weeks going in and out for short periods of time. At the range, I do double up with muffs over these, but I have hereditary hearing loss, so I do everything I can to protect my remaining hearing.
