3M PELTOR Skull Screw Communication Tip Replacements, Pack of 10, CE Approved, Replacement Skull Screws Eartips, Push to Fit Style, Hearing Protection, Gray

I will agree that the Skull Screws are initially difficult to insert. I had the same issue, and was ready to give up, but I perservered. Pinching and rolling the Skull Screw to compress and make them easier to insert will help, as will wetting and gently pressing and wiggling while directing them inwards. It still takes me some time to insert a fresh pair, but the time expended is worth it. The noise reduction, comfort and when combined with the EEP-100 sound quality is almost as good as the $1000+ custom molded you can buy for a fraction of the cost. I've had the custom electronic plugs, and the Peltor/3M EEP-100s with the Skull Screws are a better value.

Work great with Peltor/3M EEP-100, much nicer in my ears than the plugs that came with.Also, it's not mentioned anywhere on the product page, but you are getting a pack of 25 or 30 plugs.

First, these are not standalone earplugs! I use these with my 3M PELTOR TEP-100 Tactical Digital Earplugs. Overall they are exactly what you want for when the original tips wear out, and this isn't a bad price for such a quantity (I go through one pair about every 3 months with weekly use). The reason these tips only get 4 stars vs 5 is that the sound channel can close off when inserting them, which doesn't allow the amplified sound from the TEP-100 earplugs to get through. In those circumstances, just take them back out and reinsert. Regardless, better than any of the other options as they have the highest NRR of any option for TEP-100 tips.

I have the ISOtunes Pro Aware Bluetooth hearing protection. The earbuds themselves are awesome, but the factory supplied tips do not seal to my ears and they are painful after a couple hours of use. These 3M ear tips revolutionized those earbuds. They work so much better than I thought with the proper tips on them. It's like purchasing an entirely new upgraded product. I can't even hear myself talking when I turn the low DB pass through off.Be aware that these tips are not universal, but because they come in a pack of 10 I went ahead and tried them on my other earbuds and they didn't fit. They do screw right onto the isotunes just fine.

Work great with my TEP 100s

The 3M Peltor Skull Screw foam tips offer a 29db noise reduction when used with the 3M Peltor Earbud Noise Isolating Headphones 2600N. The fit and finish is very similar to the standard, foam earplugs you can buy at any local pharmacy- except that the earphones attach to the wide section of the cone...When inserted correctly, these do offer noticeable noise isolation. And, music from the headphones does come in fairly clear. Background wind noise is still present at any freeway speeds- though these work better than anything else I've tried...The only 2 things that I don't like about this setup. First, the rod of the earphone itself inserts into the cone of the foam tip, which means a hard plastic screw-like projection actually inserts inside your ear. And, inside a helmet, it's not exactly 100% comfortable. Every helmet fits slightly differently, and as most people know, properly fitting helmets should be very snug. As such, the rubbing of the foam and earpiece on the inside of the ear does hurt a little if worn over an hour or so... Second, as with all foam earplugs, the suction created for the sound isolation is very sensitive. That is, even a gentle tug on the cables can change the snugness and/ or cause some leakage or suction differences. Even if inserted firmly and properly, it's still possible for micro movement to occur. Again, inside a snug helmet, this means sometimes moving around results in a slight change in pressure, which is annoying. This can cause one ear to have better sound isolation than the other and unequal music volume, and unequal sound isolation.Bottom-line is that thus far, I have not come across a better solution. But, the protruding ear stem into the foam and snugness inside a helmet does make this solution unfeasible for tighter-fitting helmets. It would work great, however, for non-full face helmets, like for cycling or what not. Not perfect for full-face lids though.

They’re pretty easy to roll and narrow down even in the cold. Insertion and expansion is easy and complete since it’s tapered. Sound quality coming through is perfectly fine. No uncomfortable ear pressure or falling out.

I really wanted these to work, because of the better NRR, but they are, simply, too large. The biggest problem with the size is, while you might be able to mostly get them in, the poor fit reduces the effective NRR and, in my case, the Triple-C’s, with the slightly reduced NRR, did a better job of reducing sound. My rating is also influenced by the fact that returns are not possible, which I can kind of understand for this kind of product, but vendors might need to make some more leeway here because there is no trial size option and this is an online sale.
