A better way to quiet, whenever, wherever you want
- Safe by Design—biocompatible, low pressure inflation, durable, washable, reusable, recyclable
- Easy to Use—no rolling needed
- Inflate instantly to seal your unique ear canal
- Comfortable for long-term wear
- Fits more ears and won't fall out—even the most hard-to-fit ear canals
HOW IT WORKS
Unmatched comfort & hearing protection
Slip tip into your ear — easy to insert
Press bulb to inflate — now you are protected
Pull tab to deflate — now you can hear
Withdraw tip from your ear — easy to remove
Two sizes. One best fit
Every ear canal is shaped differently — that's why Fluid™ earplugs use fluid inflation to seal yours comfortably. However choosing the right size remains critical. Too small, and the tip may not inflate enough to seal your ear canal effectively. Too large, and it can create unnecessary pressure, leading to discomfort over time.
- Large — designed to provide a secure, comfortable fit for most people. It's our recommended starting point.
- Small — designed specifically for people who find the Large size uncomfortable.
Not sure of your size?
Read our “Find your best fit” guidance. We always recommend trying both sizes to discover which feels and fits best — that's why we offer our biggest savings with the Fit Pack: one pair of each size, 25% off on your first order.
What customers say
You've done it. You've built a better mousetrap!
— Eric Miller
I've tried numerous ear plugs over the years, but these stand out as a game changer. The comfort and seal quality are unmatched. The fit is superb, very comfortable.
— RossSurferWestern Australia
These things are GREAT, and I have tried a lot of earplugs… I'll be ordering more anyway. Extremely comfortable and extremely effective.
— MindyKickstarter backer
These are genuinely the best earplugs I've ever used — they don't irritate my ears at all like other ones do.
— TJKickstarter backer
I use earplugs when racing motorcycles — foam plugs don't always seat well, and they don't always stay in place when putting a helmet on. These have done a fantastic job of solving both problems. I'm happy as can be that I tried them!
— DavidKickstarter backer
I've tried these on several flights. Very comfortable, so quick and easy to install and remove. Knocks the sound down so far it's amazing… Great product.
— RonKickstarter backer
Received mine today and absolutely love them as a motorcyclist — a great product.
— AdamKickstarter backer
Just tried them out for lap swimming and I'm very impressed. Hope you all get them soon — you'll like them!
— PaulKickstarter backer
My use case is for sleep — I sleep on my side. I am very impressed with the ease of use and the sound-blocking level. I'm looking forward to these lasting years, not weeks like traditional foam plugs.
— DustyKickstarter backer
I was lucky to be an early recipient of these, and they really work great.
— BrettKickstarter backer
Very easy to put in, especially compared to foam plugs — comfortable, and they block a good amount of sound.
— MarkKickstarter backer
They look great, they fit well and they are super comfortable.
