Test Results: After a ten-week test phase, 90% of our testers’ parents have reported that the noise reduction was very effective. Irritations caused by prolonged wearing were not noticed. The parents have reported that disturbing noise from the environment was successfully suppressed, but at the same time parents could be heard. The earplugs for kids were particularly effective in the reduction of noise caused by Events (e.g. public concert) and also pressure equalisation while flying.

During this time, our ten test subjects have experienced a reduction of ear pain by up to 90%. A significant reduction of loud flying sounds was noticed immediately after the earplugs have been inserted. Two out of ten test persons have used the earplugs only for flying. The remaining subjects have also used the earplugs at loud events, bathing and while swimming (e.g. Summer vacation).

The overall test result is very positive. The BOLLSEN product stands out from other products mainly due to its effects. After only seven days, our test persons have noticed a significant improvement in the quality of life. There was no heat sensation and, even after two weeks of use, no irritation in the ears. Our conclusion: These earplugs offer optimal protection against loud noises during sleep without any undesired side effects.  

Instruction for Use: With your index fingers insert the earplugs carefully in the ears and rotate them slowly into the ear canal. Our test persons were very satisfied with the use of the earplugs and are positively surprised by their almost invisible and optimally fitting shape.

Protection of the Environment: Thumbs up on more time for the concept of reusability of the product. Furthermore, we are pleased to have finally tested a product from the EU, since shorter distances also mean less CO2 emissions in the air.

Life Span: The manufacturer advertises that the product can be used 100 times, also for the sake of the environment. One pack of earplugs lasted with our users for about 5 – 6 months. The test persons wore the earplugs on a daily basis.

How Many dB Do the Earplugs Dampen? According to the manufacturer, the earplugs have a SNR of 24 dB and provide a constant sound reduction at high (H), medium (M) and low (L) frequencies: H=24 dB, M=21 dB, L=19 dB. The attenuation value was tested according to ISO standard 4869-2 by an independent German testing institute.

The Service Guarantee Promise: BOLLSEN Hearing Protection advertises its products with a money-back guarantee, as the company obviously believes very firmly in its products. Of course, we have also tested this option and returned a pair of used earplugs after 35 days. We have been refunded our full payment amount two days after the receipt of the goods. Once again, we are pointing our thumbs up. Customised earplugs for sleeping are excluded from this offer.
