Hearing protection devices like earplugs and earmuffs often use two different ratings systems (both in decibels, or dB) to gauge noise reduction: NRR (Noise Reduction Rating) and SNR (Single Number Rating). Both are standardized ways of estimating how much sound the earplugs block, but they come from different testing systems. The U.S. commonly uses NRR, which tends to be more conservative; SNR is the European standard and often shows slightly higher values. In practical terms, they give you a ballpark idea of how much quieter the world will seem when you wear the plugs, but your actual experience will depend on fit and how well the plugs seal in your ears.

Listen for yourself! In this video, Dr. Steve Taddei provides a hands-on and lab-tested review of Loop Engage 2, Experience 2, Quiet 2, and Switch 2 that includes ratings and sound samples.
I’ve been using Loop earplugs for several years—at concerts, woodworking in my garage, and even during nights out in busy restaurants. They’re stylish, affordable, and easy to wear. But do they actually perform well, protecting your hearing and providing good sound fidelity on the specific models? That’s what I set out to answer in this hands-on and lab-tested review.
At the HearAdvisor lab, I ran each of Loop’s four latest models—Engage 2, Experience 2, Quiet 2, and Switch 2—through testing. I also wore them in real-world environments, from music venues to quiet study spaces.
