Mack's Ultra Soft Foam Earplugs 50 Pair 33dB Review (2026)

Who this pack fits

This 50-pair pack is built for travelers who want noise blocked out cheaply and do not want to think about washing or losing a reusable pair mid-trip. It suits hostel dorms with snorers, red-eye flights with crying babies or loud engines, and anyone doing a long work trip who wants a fresh pair every night without extra fuss. Because the pack lasts many trips, it also works for travelers who want to keep a stash in a toiletry bag, a glovebox, and a nightstand at the same time rather than buying single small packs repeatedly. Musicians, concertgoers and light sleepers who already know foam plugs work for them get the most value here, since the pack size rewards frequent use rather than occasional travel only.

Noise reduction rating

Mack's rates this pair at 33 decibels of noise reduction, which the brand markets as its highest NRR foam option, aimed at blocking heavier noise than snoring or a quiet cabin, such as engine drone, loud roommates, or nearby traffic. NRR numbers are lab ratings rather than a guarantee of real-world silence, and how much noise actually gets blocked depends heavily on rolling the foam tightly and seating it deep enough in the ear canal, which is true of any foam plug regardless of brand. Travelers who have struggled with lower-rated plugs letting through low rumbling sounds like plane engines may notice a real difference stepping up to a 33dB rated plug, while people mainly blocking quiet ambient noise may not need the highest rating available.

Material and comfort

The plugs use Mack's own slow-release foam formula, marketed under the name Comfy Cush Comfort Foam, which is designed to expand more gradually after rolling than stiffer foam plugs, reducing the initial pressure feeling in the ear canal. The tapered shape is meant to seat comfortably for extended wear, which matters for overnight flights and long bus or train rides where plugs stay in for many hours rather than a quick nap. Made in the USA is a detail Mack's highlights on the packaging and listing, and the brand positions itself as a doctor-recommended name in foam hearing protection, which is part of why it shows up repeatedly across pharmacies and outdoor retailers rather than just travel-specific stores.

Pack contents and value

Fifty pairs is a genuinely large supply for most travelers, likely to outlast several trips even with nightly use, and the per-pair cost works out far lower than buying premium reusable plugs upfront. The listing includes a small plastic keychain travel case, useful for carrying a spare pair loose in a daypack or jacket pocket without digging through the full box. The trade-off against reusable silicone plugs like Loop is waste, since foam plugs are meant to be thrown away after a few uses rather than cleaned and reused indefinitely, which matters to travelers trying to pack lighter and generate less disposable trash on the road.

How it compares

Against reusable options like Loop Quiet 2, Mack's foam plugs cost less upfront and need no cleaning, but they generate ongoing waste and lack the low-profile, semi-transparent design some travelers prefer for public use. Compared with Mack's own Flightguard or Pillow Soft silicone lines, this ultra soft foam version leans toward maximum noise blocking rather than pressure regulation on flights or a moldable putty-like fit, so the right pick depends on whether blocking sound or managing cabin pressure is the bigger priority. For a one-bag travel kit, a handful of these paired with a sleep mask like the Manta Pro covers both sound and light for overnight flights, and the bulk pack means you can share spares with a travel companion without running short.
