Nissan’s Latest In-Car App Is a Godsend for Music Enthusiasts

Every drive needs the perfect soundtrack
No matter if you are an everyday commuter, a dedicated gearhead, or the protagonist from the movie “Baby Driver,” music is an essential part of driving. Whether you’re cruising down the highway or stuck in rush-hour traffic, the right music can elevate your entire driving experience, even if your journey is just across town. The proper set of songs has the power to set the mood, energize your morning, or help you decompress after a long day.

But here’s the thing: even the best playlist falls flat if your car’s audio system isn’t doing it justice. For true audio enthusiasts, achieving the perfect sound is almost a ritual. You can spend countless hours fine-tuning bass levels, treble, fade, and balance, just to find that perfect sonic sweet spot. It’s an obsession that non-audiophiles simply don’t understand, but when everything clicks into place, and it hits right, it’s magic.

The thing is, all that fiddling assumes your car’s audio system understands how your ears actually work. However, everyone’s hearing is different; some frequencies come through crystal clear, while others get lost in the mix. Traditional equalizers require you to guess what needs adjusting, turning audio customization into an endless game of trial and error.

This obsessive attention to audio quality is exactly what Nissan is tapping into with their latest innovation: Personalized Sound. Frankly, it’s a game-changer that can save us time and frustration.

Enter Personalized Sound
Launched on December 15, Personalized Sound is a free app available on the Google Play store on any Nissan or INFINITI vehicle equipped with Google built-in. According to Nissan, it’s the first in-vehicle hearing test of its kind in the U.S. auto industry. It creates a custom audio profile based on your unique hearing and optimizes every song to match how your ears perceive sound.

The setup is surprisingly simple. After downloading the app, you take a three-minute hearing test right on your car’s infotainment screen. The app plays tones at varying loudness and pitch, you tap to indicate how well you hear each one, and boom, you’ve got a personalized audio profile. The system then uses your results to fine-tune a 10-band equalizer, adjusting frequencies from 50 hertz (Hz) all the way up to 1,200 hertz in a similar way to the bass and treble knobs of yore.

“After taking the test, most drivers will notice a clear difference with their new audio profile,” said Mitchell Pope, a senior product planner at Nissan who spearheaded the project. “They’ll often pick up details they didn’t before, even in songs they’ve listened to countless times.”

The new feature is a collaboration between Nissan staff dedicated to sound
Nissan says that it developed the entire thing in-house in less than 18 months with a team that included individuals with different sonic strengths. Pope, an amateur musician raised in Nashville — the music city and Nissan North America’s home base — said that Personalized Sound began as a passion project that he first shared with the Nissan team in early 2024.

“I loved the level of customization offered in some premium headphones, and I wanted to bring that to the automotive world,” Pope said. “From the start, I also saw this as a clear way to help the 36 million Americans living with a hearing impairment.”

Pope worked on the project with engineers and other product planners, which included key team members who have hearing impairments. One developer, Patrick Fields, a Nissan program analyst who lost some hearing during his Army service, not only said that the feature was “ideal for music lovers” like him, but he also called it “a tangible representation of Nissan’s commitment to accessibility.” 

The team even included Ashley Baird, a Michigan Tech student interning at Nissan’s Technical Center near Detroit, who helped code the hearing test and equalizer functionality to ensure seamless integration with the car’s existing audio system, without creating compatibility issues.

“Because the app needed to run like a standard Android app, I couldn’t plug my code directly into the car’s audio system or interact with it in the way that the existing equalizer does,” Baird explained. “It took extensive testing to find a way to interact with the car’s media system. I ended up discovering an Android audio processing effect that lets you tap into the sound that’s already going to the speakers and adjust it, so the app could apply the changes directly to supported audio sources in the vehicle.”

Personalized Sound works across both standard and premium audio systems in compatible vehicles, including the 2025-2026 Nissan Armada, Murano, and Rogue, as well as several INFINITI models such as the QX80 and the upcoming QX65. At launch, it optimizes audio from Bluetooth and in-vehicle sources like Spotify and Audible, with additional compatibility coming in 2026.

In addition, if you share your vehicle, multiple drivers can download their own Personalized Sound app and link it to their driver profile or key fob. So if your partner or child thinks “good bass” means rattling the windows, you’re both covered. 

In internal testing, 96% of participants said they’d keep their Personalized Sound profile activated. That’s not surprising when you consider the alternative: spending twenty minutes in a parking lot or on the side of the road manually adjusting equalizer sliders or hopelessly tapping on virtual ones on a touch screen, hoping you’ve hit the sweet spot.

“The best part was seeing people try the app for the first time,” Baird said. “I think a lot of people expected the app to be very basic. It was awesome to see them realize that something they could just download from the Google Play store could offer so much audio customization that their car didn’t previously have.”

Final thoughts
As an avid music listener with a Spotify “listening age” of 62, I can see that Personalized Sound can be more than just another tech feature, but rather a streamlined, simple path to perfect sound. Whether you’re an audiophile, someone with hearing loss, or just someone who wants their favorite songs to sound amazing, it’s nice to see a mainstream manufacturer like Nissan take a creative route to a feature that many buyers scrutinize.

Although many people may see this as a “vanity feature,” I can envision this being a feature copied by not only other manufacturers but also the big names in premium in-car sound, such as Bang & Olufsen, Bose, Bowers & Wilkins, Burmester, and Mark Levinson. After all, if you’re going to spend a few Gs on a premium stereo setup, it should be really easy to set up to make it sound good.
