•Lowers potentially dangerous noise levels above 85 dB (like the roar of a racing engine, which can exceed 130 dB) while allowing safe sound levels below 85 dB to be heard
•16dB Noise Reduction Rating (NRR) with stoppers in
It does NOT state the amount of noise reduction WITHOUT the stoppers

I do not own a pair. Reading the info from the link with the stoppers in they offer a 16dB NRR. You do understand this is NOT much protection from noise.
I am curious as to how they claim the reduction in noise without the stoppers in. No pun intended but it sounds to good to be true.
