4pc Replacement Posts/Guide Arms Compatible With Peltor Comtac Headsets & Earmuffs

Great product and fast shipping. I ordered these clips to replace a broken clip on my 3M Worktunes Bluetooth ear protection. They fit perfectly and appear to be of a thicker plastic than OEM. Not an exact replacement as far as looks, but functionally they work great, and I don’t wear these on the runway anyway. So far, so good. Will update if things go south.

I can’t believe it was so expensive but at least I have extras now and I didn’t have to replace the headphones. Seems like something I could 3-D print, but couldn’t figure out where to find a template. I did shop around and this was the best price so no complaints.

The only thing I didn't like is the OEM arms have like a rubber cap on the end, these don't. Not a showstopper, but would have been a nice to have.Note re installation, you'll see they don't go quite on as you might first think. Look where the arms 'C' can go if you rotate the ear muff like 90 degrees, and you'll see the muff post is not circular but oval, so the new arm can go where the oval is thinner, then you rotate it back to proper position. You;ll figure it out... you're doing it right when there is no effort needed to put it on.

Cheap quality and did not have the rubber stabilizers as pictured. They also fit the metal poles on an authentic Peltor headband so loosely that the headset would wobble around and lose adjustment. I would not trust these to maintain the seal of your hearing protection in a helmet mounted configuration. Returned these due to the issues above.The plastic seemed decent, but that’s about the only good thing I can say about these.

The only difference I've noticed between this product and the 3M your piece fittings are the long piece that goes in the back. 3M pieces have a metal shaving I guess you would call it that lock steer piece into place, this product does not have that but I honestly don't miss it or even care.

I needed to convert my 3M Peltor Comtac III from a neck band to a helmet mount. The only way to do this was to purchase new guide arms. The install is pretty simple and all that you need to do is rotate the arms 90* and put light pressure on the arm to "click" it into place. Unfortunately the plastic is not as strong as the original 3M arms and they ended up cracking. I would not recommend these for replacing your 3M guide arms. Just stick with the original units.

They fit nicely on the 3M Radio Hearing Protection Headphones. Old one had cracked making the Headphones pretty much useless.So this saved me from having to buy a new set! I’m happy!

They only lasted about a week, and then started sliding like the old ones.

I just received these and installed them on my headset that had one broken arm. They are very similar and fit as expected and were very easy to put on. You do have to clock the earmuff so that the pin will go into the arm without cracking it because the pin is not perfectly round, they have a slotted side to allow the arm to click on. I've seen other people on here complain that the plastic isn't good on these and I think that's likely what they did wrong and it led to them breaking the new arms.
