About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

KLANG GUARD®
mini

The Klang Guard Mini left an extremely positive impression in the test. Take care of your baby’s precious hearing with this hearing protection. For babies under 18 months whose fontanel is not yet closed, it is extremely important not to exert any pressure on the head. This hearing protection makes it possible and the headphones have an optimum hold on the sensitive head. Thanks to a specially developed, soft and non-slip headband, they offer a comfortable and secure fit that adapts to every baby’s head – without any uncomfortable pressure. The quality is tested and certified. The elegant fabric bag protects against dust and foreign objects.

The Mini Sound Guard is very easy to use. The Mini+ hearing protection was developed to significantly reduce noise exposure for babies’ sensitive ears . The Mini Sound Guard is available in mint and pink. Unfortunately, the Velcro strap wears out relatively quickly. Despite this, the quality is high. The product itself is very robust. Thanks to a specially developed, soft and non-slip headband, they offer a comfortable and secure fit that adapts to every baby’s head – without any uncomfortable pressure. The baby hearing protectors can be used flexibly and protect sensitive ears not only at loud events such as sports and music events or carnival parades, but also in everyday life, whether in traffic or at family celebrations. All in all, the Mini Sound Guard is very well thought out and highly recommended.

ℹ️ Finally, we examine how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it?
