Part of The Ultimate Long-Haul and Packing Survival Guide

- Foam wears out
- Need correct insertion
- Can't hear alarms easily
Quick take
Mack’s Slim Fit earplugs are soft foam plugs sized for smaller ear canals, with a 31dB noise reduction rating and a keychain travel case.
Where to buy: Mack’s Slim Fit Soft Foam Earplugs on Amazon (typically about $5 to $10).
My take
I’ve tested a lot of earplugs, and these are the best ones to sleep with: the best balance between comfortable and quiet. Anything else is either less quiet or less comfortable. The little case holds two earplugs and clips on, which is nice and fun on a plane. They cost more per pair than I’d like, but they’re the best earplugs to sleep with, in my opinion.
What it is
Foam plugs work by expanding to seal the ear canal. Standard sizes hurt some ears; the slim version fits more comfortably for a full night.
Where it fits on the road
Bangkok traffic, roosters in Chiang Mai, karaoke next door: city stays are loud. Earplugs plus a blackout mask turn a noisy room into a reasonable night’s sleep.

How it compares
- Loop Quiet. Reusable silicone, softer seal.
- Howard Leight MAX. Higher rating, larger fit.
- Noise-cancelling earbuds. Great on planes, uncomfortable for sleep.
Choosing a quiet place to stay
Check reviews for noise, ask for a room away from the street, and look at quiet neighborhoods like South Samrong for long stays.
Price and value
Expect to pay about $5 to $10, though prices on Amazon move often, so check the current listing before buying. Outstanding value: cheap, effective sleep insurance for noisy places.
How I scored it
The 5.0-out-of-5 score is led by my own recorded thoughts, checked against what buyers report across retailers, weighed on value, build quality and how well it fits a travel and remote-work life. Read the full method on the editorial policy page.
3 tips to get the most out of it
- Roll, pull the ear up, insert, hold for 30 seconds. That’s the seal.
- Replace pairs weekly. Worn foam seals poorly.
- Set a vibrating alarm. You may not hear a sound alarm.
FAQ
Are they reusable?
A few times; replace when they lose shape.
Will I hear my alarm?
Possibly not; use vibration.
Are they good for flights?
Yes, they reduce engine noise.
Who it’s for (and who should skip it)
Good for light sleepers with smaller ears. Skip them if you need to hear a baby or alarm. This is one piece of the Long-Haul and Packing Survival Guide, which covers packing, sleep and comfort on long trips.
Bottom line
Cheap, effective sleep insurance for noisy places.
