Sennheiser and smart trial integrated in-car audio experience for urban driving

Background and context

Table of Contents

Audio specialist Sennheiser and urban mobility brand smart are working together on a new in-car sound concept aimed at city driving. While both companies are known in their respective sectors, this collaboration highlights how automotive and professional audio technologies are increasingly intersecting.

As cars evolve into connected, multimedia spaces, manufacturers are looking beyond traditional stereo systems. Immersive, configurable sound is becoming a key part of how brands differentiate the driving experience, particularly in compact vehicles designed for dense urban environments.

The initiative from Sennheiser and smart sits in this broader shift, where in-car audio is expected to support entertainment, navigation, communication and, in some cases, branded content or location-based experiences.

Key announcement

Sennheiser and smart are piloting an advanced soundscape for a smart model configured for city use. The system is designed to provide an immersive audio environment that adapts to different driving situations and user preferences.

According to the companies, the concept combines precise loudspeaker placement with digital signal processing to create a spacious listening field inside a relatively small cabin. The goal is to deliver clearer speech, more engaging music playback and a more defined sense of spatial audio than conventional set‑ups in this vehicle class.

The prototype environment also explores how audio can shift function seamlessly: from rich, full-stage music playback when the car is parked, to more focused, speech-optimized sound when navigation instructions or calls take priority in motion.

While detailed technical specifications have not been fully disclosed, Sennheiser indicates that its expertise in immersive formats and psychoacoustics underpins the system. The collaboration reflects a trend of audio companies applying live and studio know-how to automotive use cases. More information on Sennheiser’s automotive and immersive solutions is available on the company’s official website at sennheiser.com.

Industry impact

For the wider AV and event technology community, this type of project signals new potential touchpoints between in-car environments and content typically associated with live and installed sound.

Automotive cabins may increasingly function as controlled listening rooms, where spatial audio content produced for venues, installations or streaming platforms can be adapted for drivers and passengers.
Brands involved in experiential marketing and city events could see cars as additional endpoints for campaigns, using tailored soundscapes that extend experiences beyond fixed locations.
Audio workflows used in concerts, broadcast and immersive installations—such as object-based mixing and room simulation—are finding a parallel in vehicle interiors.

For car makers, partnerships with professional audio manufacturers offer a route to differentiate compact and electric models without relying solely on hardware upgrades. For AV professionals, these collaborations create new demand for skills in spatial design, content adaptation and system tuning for non-traditional spaces.

Why this matters

As urban mobility shifts towards smaller, connected and often shared vehicles, the in-car experience becomes a competitive factor. High-quality sound, once a premium add-on, is moving closer to a core feature that shapes how users perceive the brand and the journey.

For event and AV specialists, developments like the Sennheiser–smart pilot show how techniques from live sound, installations and broadcast can translate into mobile environments. The same principles used to build immersive spaces in venues are now being explored in cars, opening new opportunities for content creators, integrators and system designers.

If projects like this move from pilot to production, urban drivers may encounter more consistent, high-quality audio experiences—whether they are listening to music, attending virtual meetings from the car, or engaging with content linked to the cityscape around them.
