08 Aug Car Audio 2025: Best Premium Sound Systems
The world’s finest concert hall rides on four wheels. Today’s premium vehicles feature sound systems that rival – and sometimes surpass – high-end home cinema setups. But which brand delivers the best audio experience in 2025?
Burmester: When the Car Becomes a Concert Hall
Burmester audio systems are factory-fitted in Mercedes-AMG and Porsche vehicles – and widely regarded as the industry benchmark. The 3D surround sound system in the S-Class – featuring 30 speakers and 1,750 watts of power – is simply out of this world. Anyone who’s driven with it once will notice only shortcomings in their own car thereafter.
Bang & Olufsen: Scandinavian Precision in BMW and Audi
B&O systems are available in select BMW and Audi models. The sound is neutral, precise, and highly detailed – no artificial bass boosting, just honest audio reproduction. Especially impressive is the adaptive cabin tuning, which dynamically adjusts to both the vehicle’s interior acoustics and driving speed.
Harman Kardon vs. Bose: The Mainstream Champions
For premium audio upgrades up to €2,000, Harman Kardon (fitted in BMW, Hyundai, and Lexus models) and Bose (standard in Mazda and base-trim Porsche models) deliver the best value for money. Harman Kardon delivers a warm, punchy sound; Bose excels in spatial imaging and detail resolution. Jazz lovers: choose B&O. Bass enthusiasts: go with Harman Kardon.
