The sound quality changes when the INZONE H9 II headphones are turned off while connected via a headphone cable
When the headphones are connected via a headphone cable, you can use them when powered off. This is designed for temporary use when charging is not possible.
However, when using them while powered off, the noise canceling and Ambient Sound Mode functions will be disabled, and the sound quality may differ from when the headphones are turned on. Therefore, we recommend using the headphones while they are powered on (if charging is possible).
