Q: Does the Bluetooth dongle support TV?

Q: Why do I get a driver error when I install the driver?
A: Maybe the built-in Bluetooth on the computer causes a conflict. Please disable the previous Bluetooth first.

Q: Can the USB Bluetooth adapter connect to the same device at the same time, such as two earphones?
A: No, you can connect 5 devices at the same time, but they must be different types of devices.
Q: Does the USB Bluetooth adapter support voice calls?
A: If your Bluetooth headset has a microphone function, it supports voice calls.
Q: Can the USB adapter be connected to Gaming Controllers such as PS/XBOX?
A: It only supports connected PS4, X BOX ONE S and later series Gaming Controllers. Bluetooth devices all have latency issues（Latency<250ms）, If you need to connect game controller devices and have requirements for latency,
We recommend that you use a wired connection or a dedicated 2.4g adapter to achieve ultra-low latency and stability .
