Notes:
① A compatibility issue may occur to certain Android mobile phones or music players due to system and hardware differences.
② Some mobile phones are required to turn on the OTG function, so as to use the DS1 For detailed settings please consult the support of mobile phones.
③ Some mobile phones may show the “non-certified Type-C digital headphone” You can ignore the message and use it normally.
Notes:
① Only iOS 10.0.2 and above are supported. Due to the iOS system itself, Apple devices below this version cannot be supported.
② Since there is a limitation on the power supply to external USB devices from iPhone, DS1 with high output power may have stuttering or no sound problem at high volume.
[Windows system]
[Macbook]
Here is the known situations:
① On some mobile phones or DSD playback software, the volume buttons on the DS1 body cannot be synchronised to control the volume of your mobile phone, you can control the volume directly from your mobile phone.
② Some phone power management policies do not allow third-party apps to run in the background by default. This may cause the APP to pause in exclusive USB audio access mode after the phone has slept for a few seconds. You can manually set the app to keep working while sleeping in the phone’s battery management settings.
③ Running other apps in exclusive USB audio access mode may cause lagging or no sound issues. We will continue to optimise this issue. If you are using exclusive USB audio access mode, we recommend that you focus on listening to music. Alternatively, you can exit the exclusive USB audio access mode to avoid this problem.
