Please try the following steps
http://www.reasnow.com/forum/index.php?topic=3995.01.Connect BeroderPro to the LAN cable and USB power supply (upper left). The USB can be connected to the back port of the PS5 or directly powered from a smartphone charger, for example.
2.Press the bottom left button on BeroderPro to confirm remote connection (BeroderPro LED lights up green).
3.With this state, connect Reasnow to BeroderPro (it is essential to connect the genuine controller of the PS5 to Reasnow).
4.If the connection fails, the LED on Reasnow will blink green and red, and the connection on BeroderPro will also be cut off. In this case, unplug the cable and start over from step 2.
5.Check that both Reasnow and BeroderPro are connected and their LEDs are lit green.
6.Finally, connect the headset to BeroderPro.
7.Connect the BeroderPro audio USB (upper right) to the front port of the PS5. If a loud announcement in Chinese is played when connected, the connection is successful.
However, if steps 6 and 7 are done in the wrong order, the volume may be too low or there may be severe noise on the microphone. Also, steps 2 and 3 may need to be repeated several times, but once the connection is successful, it will be stable.
