RadiansUltimate Earbuds CEP001-P Industrial Safety Ear Plugs, Multi, One Size

First I found that it became hard too fast during kneading so not much got into canal.The material also too much so while standing up this is not a problem, when lying sideways, it is.Even more if your ear like mine, sticks out. When I put my head on the pillow, my ear changes shape but the plug doesn't.While some shaping later might be ok, I quickly found that where I think it should be flat, it shouldn't and where it should be round, it shouldn't.Too much shaping and it loses it's seal.So it's hard because it doesn't change shape, but it's soft to the touch like rubber.No issues with material (like rash or itching)Also too expensive.

I'm a hifi audiophile, a man who want the perfect sound. And i found it!I have a pair of Shure se535 in earheadphones (3 speakers in that little thing: a bass +a midrange + a tweeter speakers, yes-yes, no kidding): 500$, with Astell & Kern portable dac source: 500$. I had searched for a long time to get the perfect fit for my ears to increase the sound. Tried so many foams (yellow/black/cotton swabs... name it!), and give a try from the Radians custom molded earplugs: a discover!!!For 20$,I have increase the bass and get clearer sound. The bass is particularly incredible with theese earplugs. Bass was always a problem with in ear headphones, until now!!!For that price I have a hifi kit now. For 20$ and 30 minutes for making fit to my ears.1. cut the 2 parts in 2 (the tan silicone, the white solidifier) -give another chance if you miss your first try);2. Mix them in a regular color;3. put that in your ears and push as far you can;4. make a clean and flush earplug fit perfect to your ears;5. put your inear headphones far in your ears (throw out your older original cheap foams first!!!);6. let them bold togethers;7. after 30 minutes without doing nothing with your mouth, get it out;8. let them together take air for a while (I went sleeping...);9. separate them;10. make a hole for each earplug (if you have a Dremel, go for it, i used a knife...)11. replace it, put that in your easr and... ENJOY THE MUSIC!I will share that post for everyones I know. The only thing I don't like is Radians don't do that in black (I will try to paint it with a permanent pen...). Anyway, it's the perfect sound with a so comfortable and solid stand.Buy it and you will love it like I do!

Absolutely awful! They offer zero noise blocking, and in fact make more noise as they rub and make tiny shifts constantly in and around the ear. They seemed to sort of be working during the initial ten minute cure, but after letting them fully cure for 4-5 hours and putting them in again I discovered how useless they were.I followed directions, they hardened properly, they look like the pictures in the listing etc, they just don't do what they're supposed to. At all.I wear ear plugs daily, these were an absolute waste of money. Try Mack's or e-a-r brands for better sound cancelation/ear protection. They're not perfect, as they occasionally cause irritation, but they're so so so much better than this junk.

I bought these twice- the first time followed all instructions and found the ear plugs bulky in my ear. I bought them again and used a smaller amount of both the materials they give you and they fit much better. Unfortunately, I ignored other peoples’ reviews who said they are not comfortable to wear to sleep in. I thought they looked rubbery and would be flexible but they are actually hard when they set. So I recommend them if you are upright and wearing them, but not for sleeping.

They're pretty bad with noise reduction, I'll have to be honest. After they cured, I even tried pushing them closer to my ear canal using my palms just to see if it was a molding/seal issue, There was a -slight- improvement, but not even close to the foam earplugs I used to wear. There was a lawnmower going outside my window, and it barely reduced that noise. I highly doubt it's going to effectively quiet my roommate's talking at night.I will say that I think the biggest value in these actually comes from its alternate use in replacing uncomfortable earbud tips. They are still easy to mold and comfortable to wear. But as earplugs, theyre pretty useless.
