When the General - Accessibility - Mono Audio is turned on in the iOS settings, the monaural feature will be activated by the OS. Since the special monaural playback functionality (NEW MONO mode) of the New Monaural mixes and channels sound to the left and right ear for those with unilateral hearing loss, the intended sound quality of the application will not be reproduced when the Mono Audio is enabled.

Please disable the Mono Audio before use.
