Loop earplugs are reusable, ring-shaped earplugs designed to reduce noise volume without muffling sound the way traditional foam plugs do. Made by a Belgian company, they use a hollow acoustic channel inside each earplug that mimics how your ear naturally processes sound, paired with a filter that lowers frequencies more evenly. The result is quieter sound that still feels clear, not underwater. Loop sells several models ranging from about 17 to 27 decibels of noise reduction, each tailored to a different situation.
How They Work
The core difference between Loop earplugs and standard foam plugs comes down to how they handle sound waves. Foam plugs absorb sound unevenly. They block very little low-frequency noise (around 5 dB for sounds like airplane engine rumble) while aggressively cutting high frequencies (up to 40 dB for sharp, clanging sounds). That imbalance is what creates the “muffled” feeling where everything sounds like you’re hearing it through a wall.
Loop earplugs take a different approach. Sound enters through a small opening and travels through an acoustic channel built into the circular body of the earplug. That channel is capped with a filter that reduces frequencies more uniformly across the spectrum. In testing by SoundGuys, the Loop Experience 2 reduced low-frequency noise by up to 10 dB with standard silicone tips and high-frequency noise by up to 31 dB. The gap between low and high attenuation is still there, but it’s much narrower than foam, which means music, speech, and ambient sound stay recognizable instead of turning to mush.
The Different Models
Loop currently sells five earplug models, each built around a different listening scenario. They all share the same ring-shaped design, but they differ in how much noise they cut and how they balance clarity versus raw reduction.
Loop Experience 2
This is Loop’s flagship model for live music, festivals, and sporting events. It reduces noise by 17 dB (SNR), with an optional accessory called the Loop Mute that adds another 3 dB. The priority here is preserving sound quality so that a concert still sounds like a concert, just at a safer volume. If you go to shows regularly and want to protect your hearing without losing the experience, this is the one most people start with.
Loop Quiet 2
Built for blocking noise rather than preserving fidelity. At 24 dB (SNR) of reduction, with an optional boost to 27 dB using double tips, the Quiet 2 is aimed at sleeping, studying, commuting, and deep focus work. It doesn’t use the same filtered acoustic channel as the Experience or Engage models. Instead, it prioritizes raw noise reduction, making it closer in function to traditional earplugs but with a more comfortable, reusable design.
Loop Engage 2
Designed for situations where you need to hear people talk but want the overall volume turned down. Loop markets this for social gatherings, parenting, open offices, and noise sensitivity. The reduction is moderate enough that conversations remain intelligible while background noise fades. This is the model most often recommended for people who find everyday environments overwhelming but still need to interact with others.
Loop Dream
Loop’s sleep-specific earplug, offering the highest noise reduction in the lineup at 27 dB (SNR). The design prioritizes comfort for side sleepers and extended wear overnight. If a partner’s snoring or street noise is the problem you’re trying to solve, this is the model built for that.
Loop Switch 2
The most versatile (and most expensive) option. It has a mechanical dial that toggles between three modes: Engage mode at 20 dB, Experience mode at 23 dB, and Quiet mode at 26 dB. Instead of buying separate pairs for different situations, the Switch lets you adjust on the fly. Heading from a dinner conversation to a loud concert? You twist the dial instead of swapping earplugs.
Fit and Sizing
Loop earplugs come with silicone ear tips in four sizes: extra small, small, medium, and large. Getting the right fit matters more than most people expect. A loose seal drastically reduces noise reduction, while the wrong size creates pressure and discomfort during extended wear. Most Loop models also offer optional foam tips, which compress to fit your ear canal more snugly and can increase noise reduction by a few decibels. Foam tips shouldn’t be washed with water, though, as moisture degrades the material. Silicone tips can be rinsed with soapy water and air dried.
Cleaning and Maintenance
How you clean your Loops depends on the model. The Quiet 2, which has no internal filter, can be rinsed or submerged in water without issue. The filtered models (Experience, Engage, and Switch) should not be submerged because water can damage the filter inside the acoustic channel. For those, you remove the silicone ear tips and wash them separately, then wipe down the earplug body with a damp cloth.
Loop sells a small carry case that clips onto a keychain, which helps keep the earplugs clean between uses. Tossing them loose into a pocket or bag lets lint and debris build up in the acoustic channel, which can affect both hygiene and sound quality over time.
Use Cases for Sensory Sensitivity
Loop has gained a significant following among people with autism, ADHD, sensory processing differences, anxiety, and hyperacusis (a condition where ordinary sounds feel painfully loud). The appeal is straightforward: filtered earplugs reduce overall volume without cutting you off from your environment. You can still follow a conversation, hear an announcement, or stay aware of your surroundings while taking the edge off sounds that would otherwise trigger overwhelm or anxiety.
The Engage model tends to be the most popular for this use because it keeps speech clear while softening the background noise that tends to be the real problem in crowded, chaotic environments. Parents with sensory sensitivity often use them to manage the noise of young children without missing what the kids are actually saying. For workplaces, the lower reduction level means you can still participate in meetings and casual conversation while filtering out the hum of open-plan offices.
What They Don’t Do
Loop earplugs are consumer hearing products, not industrial hearing protection. While they reduce noise meaningfully, their reduction levels (17 to 27 dB SNR) are designed for comfort and everyday scenarios. OSHA requires hearing protection when workplace noise exceeds 90 dBA as a time-weighted average, and environments like construction sites or factory floors typically demand higher-rated protection, often earmuffs combined with earplugs. Loops are built for concerts, commutes, sleep, and sensory comfort. They’re not a substitute for professional-grade hearing protection in high-noise occupational settings.
