Xiaomi responds that the sound of the SU7 Ultra wave has become quieter.

On September 20, Xiaomi Cars responded to a netizen's question about the reason for the decrease in sound volume of the SU7 Ultra after this OTA upgrade: "We noticed that some users have felt a booming sensation in the engine sound since the delivery of the Xiaomi SU7 Ultra. Therefore, to address this issue, we have optimized the low-frequency range of the Xiaomi SU7 Ultra's engine sound in Xiaomi HyperOS 1.10.0, reducing the booming issue in certain scenarios. Additionally, we will support independent adjustment of the internal and external sound volume in the next OTA version, so stay tuned."
