One earplug measures 2.5 cm tall and about 1.3 cm across the base. That’s a big longer than your average earplug, which makes for painless insertion and removal. Just be sure not to shove it all the way in, as you run the risk of earwax buildup and damage to your ear drum.
We recommend replacing your pair every 3-4 days to make sure you aren’t breeding bacteria. Wash after use with warm water and soap.
Test ①: Fit
Test ②: Noise Reduction
We tried on the earplugs and made sure they
The earplugs did protrude from the ears a bit, but that was to be expected, given the length. But they felt so natural that we forgot we were wearing earplugs after some time, and they didn’t fall out either, so we were satisfied with the fit.
We used a sound analyzer from Rion Co., Ltd. to measure noise reduction. We put on a pair of headphones and had the machine keep playing beeps at successively lower volumes until we couldn’t hear them anymore.
We did this both with the earplugs in and without. We then matched up the numbers and calculated the NRR of the Pura-Fit 6800.
Fainter background noises (such as the sound of your neighbor shuffling around upstairs) are pretty much inaudible; you’d have to really strain your ears to pick up anything.
We also double-checked Moldex’s claim that the earplugs earned a NRR of 33 db and found it to be true. They reduced background noise to an indistinct hum. That means they’ll be enough to block out the ruckus of your family/co-workers/neighbors’ lives going on around you.
