These things are magic
Excellent. When used in conjunction with ops corps system you hear better than without them while having full protection.


The Only Way to go
My ears are bad enough, so the added layer of protection combined with the ability to hear well under my Opscore Amps, make these buds imperative. The guys at HCC were great on comms when there was an added delay due to black Friday, and they offered the best price around. Thank you!

Awesome earplugs.
The NFMI earplugs transmit sound clearly with no loss in sound volume, or directionality. They are comfortable to wear. I have the AMP headset on the lowest volume setting which sounds completely natural and I forget that I am wearing the earplugs even on the lowest setting - amazing!

Great product!
Let me tell you something about HCC as a company… I bought the Ops Core AMPs (non NFMI) for like $1100. The NFMI amps came on sale a few days later and a I reached out to them to see if I could get the order switched but keep the price the same. The basically demanded I get a refund and gave me a $104 gift card! Amazing company that I’ll be buying from many times over!!!

Amazing
These are amazing. I don't think I would bother spending the money on the AMP headset without these. I don't think the AMP is worth the price tag compared to Peltors or even Sordins. However, paired with these, it's totally worth the price tag. They do an amazing job of protecting your hearing while not giving up anything in terms of hearing compared to wearing AMPs without these.
