In the run-up to the test, we defined practical requirements and the following test criteria:
- Sound quality
- Functional scope
- Battery performance
In order to evaluate these criteria, we have defined several tests for the Bluetooth speakers. In order to test the sound quality, the loudspeakers are played with different genres. We pay attention to high tones as well as bass. Each loudspeaker is checked for available connections, apps and included accessories. Devices which, according to the manufacturer, are waterproof or protected against splashing water are tested accordingly. Finally, the battery capacity of all devices is measured.
In order to rule out errors and to ensure the load of everyday use, each test takes place in several runs.
The test criteria receive percentages depending on their importance. The final score is then objectively calculated from the criteria using an algorithm.
Our product selection is based on observation of the current market. In addition to popular branded products, we also include insider tips in our selection. The test field is also determined by analysis and evaluation of customer reviews and external tests (e.g. Stiftung Warentest). Criteria such as price and functionality are an important factor for us.
The devices are purchased anonymously or lent to us by the manufacturer. Dealers and manufacturers have no influence on the tests and our evaluation.
As soon as new relevant products come onto the market, our test field is extended by these. The new products go through the same test as the already tested devices.
