Mack's Ultra Soft Foam Earplugs
Best for: Maximum noise blocking on a budget
The maximum-quiet workhorse — 33dB of blocking in the softest high-NRR foam Mack's makes, the pick when you need to bury a snorer or thin walls for pennies a night.
Worth itThe highest published NRR here, for pennies a night. If the goal is raw blocking rather than reusability, this is the number to beat.When the job is raw silence, foam still wins, and Mack's Ultra Soft is the sleep-store classic. At 33dB NRR it sits among the highest-blocking plugs you can buy, and Mack's makes it in an unusually soft foam that's easier to tolerate than most industrial equivalents. In a 100-pair bag it costs pennies per night, which is why it's sold by the millions across pack sizes. The trade-offs are the trade-offs of all foam: you replace it every few nights, the fully-plugged feeling isn't for everyone, and a plug can work loose by morning. But for the most quiet per dollar against a snoring partner, this is the benchmark.

Frequently asked questions
Mack's Ultra Soft vs Howard Leight foam?
Both are top-tier blockers. Mack's foam is softer and rated a touch higher (33dB vs 30dB); Howard Leight's is engineered as 'low-pressure' so it blocks nearly as much with less of the tight, throbbing seal. Softest + highest NRR: Mack's. Least pressure feel: Howard Leight.
Mack's Ultra Soft vs Flents Protechs?
Both are 33dB foam sleep plugs at value prices. Mack's foam is a bit softer; Flents has far more reviews (37,000+) and often costs a little less per pair. Comfort edge: Mack's. Reviews and price: Flents. You won't go wrong either way.
Mack's foam vs Loop Quiet?
Foam blocks more (33 dB NRR against Loop Quiet's 14 dB NRR) and costs less up front, but it's disposable and can feel more occluding. Loop Quiet is reusable, washable, slimmer for side sleepers, and comfier for many. Buy foam for maximum silence; buy Loop for comfort and reuse.
How often should you replace foam earplugs?
Every 2–3 uses for hygiene — foam absorbs earwax and moisture and stops expanding cleanly. In a 100-pair bag that's still pennies a night, and it keeps the seal (and your ear canal) healthy.
