Service and product testing
Quality in Focus: Where Innovation and Precision Meet
Since 1970, we have been conducting comparative product tests, starting with audio devices such as turntables and tape recorders. As products have become more powerful and diverse, Müller-BBM has developed numerous new testing procedures. The digitization and networking of consumer electronics have further accelerated this trend in recent years. We also test services, such as the user-friendliness of online portals or repair services. A central principle in all tests is the absolute comparability and reproducibility of results to ensure fair and reliable evaluations.
Our Expertise in Service and product testing

Service testing
Service Testing is essential for evaluating the quality and reliability of providers across various industries. These tests cover areas such as web, mobile, and television providers, repair workshops, and online platforms for used devices. The goal is to assess service quality, accessibility, and the availability of information provided by the vendors.
Your Benefits:
- Informed Purchase Decisions: The tests deliver reliable and transparent results that help consumers make informed choices and select the best providers.
- High Service Quality: By evaluating service quality, accessibility, and information availability, consumers can ensure they receive high-quality services.
- Comparability and Reproducibility: Absolute comparability and reproducibility of test results ensure fair and trustworthy evaluations, allowing your customers to rely on the outcomes.

Product testing
To ensure the quality and reliability of modern consumer electronics, IT, and smart home devices, thousands of individual products are tested annually in our specialized laboratories using state-of-the-art procedures. These comprehensive tests provide reliable, reproducible data to test magazines and consumer protection organizations worldwide, which they use to publish evaluations and articles. Products tested include current television technologies such as LCD, OLED, and QLED displays, mobile phones, tablets, smart speakers, headphones with and without active noise cancellation (ANC), smart lighting systems, connected thermostats, and security technology for smart homes. Acoustic investigations—such as the effectiveness of hearing protection or the sound quality of audio products—are also part of the testing spectrum. Digital toys for children, navigation solutions, and fans are tested under realistic conditions for safety, functionality, and user-friendliness. To test products in a realistic and consumer-like manner, we continuously develop highly specialized test rigs.
Your Benefits:
- Ensuring the Highest Quality Standards: Our tests guarantee that products are evaluated according to the highest quality standards. In close collaboration with our clients, we develop suitable strategies to identify a product’s strengths and weaknesses using well-founded testing procedures, ultimately delivering a substantiated quality assessment.
- In-Depth Evaluation of User Benefit: By applying cutting-edge methods and conducting subjective user tests, we ensure a comprehensive evaluation from the end-user’s perspective—confirming that products are not only technically sound but also meet users’ needs and expectations.
- Reproducible and Fair Test Results: Thanks to advanced measurement and testing environments, all devices are examined under defined and reproducible conditions. This ensures accurate and fair product evaluations.
