Yes, it does change.
However, it’s not the case that the sound automatically gets worse just because you use CarPlay or Android Auto.

There are mainly three reasons why the sound impression can change:

• The sound-quality settings of the playback app
• Differences in the connection method
• The adjustment state on the vehicle side and the audio side

For example, even with the same smartphone, how you hear the music can vary depending on the music app’s settings, your communication/network conditions, and whether you’re connected via Bluetooth or USB.
So rather than “CarPlay/Android Auto is bad,” it’s easier to understand if you think that differences show up more easily depending on the conditions under which the audio is being played.

At LOGON, we evaluate sound including these playback environments.
Even when replacing speakers or adjusting DSP, if CarPlay or Android Auto is what you usually use, you can tune the sound to match how you’ll actually use it.

In practice, we often hear requests like:

• I want navigation to stay easy to use
• I want to listen to music mainly from my smartphone
• I want to keep the factory look and usability as much as possible

That’s why at LOGON, audio proposals based on smartphone integration are not uncommon.

As a caution: if you want to improve sound quality properly,
it’s better to consider not only the playback method, but also:

• Speakers
• Door vibration countermeasures
• Whether there is an amplifier or DSP
• The finish level of the tuning/adjustment

Including these will make the differences you can feel much larger.

In other words, even in cars that use CarPlay or Android Auto, if it’s set up correctly, you can achieve sound that’s more than satisfying to listen to.
It’s a great match for people who want to enjoy convenient smartphone use while also enjoying great sound.

We often receive consultations like, “I want to keep the convenience as-is, but make the sound properly better.”
We can guide you to a sensible setup that fits your vehicle model and the way you’re using it right now—so feel free to consult us even if you’re still unsure.
