6. Can I use 2 Bluetooth headsets/devices at the same
time? For example, when watching TV with two
Bluetooth headsets?

time, please follow the quick setup in transmitter mode strictly for

7. Can it transmit and receive at the same time?
• No, you can only be in transmitter mode or receiver mode, or
bypass mode.
8. Why does the "APTX", "LL" and "HD" of the device not
lighting up?
• Please ensure that your Bluetooth device supports
aptX/aptX-LL/aptX-HD audio or that the Bluetooth device
aptX/aptX-LL/aptX-HD functions is turned on. Otherwise, you will
not be able to use the features and “APTX”, “LL”, “HD” will not
light up. Please consult the supplier of this Bluetooth device for
more support.
9. Can't get higher aptX audio (aptX-LL/aptX-HD) when
connecting two Bluetooth devices and the devices
themselves support it?

output will be output with the lowest audio type. For example, if
device A support SBC but not aptX, and device B supports
aptX/aptX-LL/aptX-HD, then the 2 devices will output SBC audio.
