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.

Wet the tip, insert and screw into the ear canal. Yes, they will drive all the way in and when in provide excellent noise suppression.I use the Peltor system when riding motorcycles. It allows me to hear everything around me while suppressing loud engine, and wind noises protecting my hearing. Oddly, I can easily hear conversations nearby at stops in the city with my full face helmet visor up. I cannot hear these same conversations when bare eared. The binaural aspect allows me to determine the direction of noise somewhat like being bare eared, although the helmet does interfere somewhat with this. However, I can usually understand from which direction emergency vehicles are coming.I liked the smaller foam earplugs which came with the Peltor devices, but they have become difficult to find, so I switched to the Skull Screws. The Skull Screws provide better dB reduction and make it easier to hear the allowed through noise.A very durable product, I clean once in a while and expect each earplug to last a month or more (I ride 100+ miles per day on average).Strong recommend, good product, good fit if correctly inserted, great dB reduction, good to great durability.

They are a littler stiffer than I thought, but they do work good. I wish they were a bit softer.

Very strong

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.

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.

Ear plugs blocked noise as advertised but insides had sharp plastic flashing that made wearing them over a work day extremely painful. May have received a defective or counterfeit set as other skull screws [non communication model] have NOT had this issue

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.
