Important Notes

1. We don't recommend to use the 3.5mm port and RCA port on the item at the same time, because it may affect the sound quality.

2. To ensure proper hardware detection, we recommend to plug the external headset into the adapter first, then connect this USB sound adapter to the computer or mobile device.

3. Mono Microphone requires a 3.5 TRS connector (not TS or TRRS).

4. For using with PS4, the output sound for Left and Right chanel will be Reversed as the sound sampling rate of our audio adapter(192K/24BIT) is higher than PS4 Compatibility(48K/16BIT).
