2AN4C-7137DUAL-MODE WIRELESS BLUETOOTH GAMING HEADSET

a. At home: b. when outside: ① Dongle does not need buttons. Plug in Dongle and enter game pairing search. Note: The headset will enter game mode only when the headset is connected to Dongle. If the headset is not in Dongle state, it is in bluetooth mode. ② Dongle has an indicator light. Note: a. Fast flash is pairing search b. Slow flash is successful connection ③ After inserting Donglethe Dongle enters the game pairing search, and the search time is unlimited. ④ In Dongle game mode, it can support uplink voice. ⑤ In Dongle game mode, it can answer incoming calls, automatically return to game mode after the call ends. ⑥ Dongle does not need to support normal Bluetooth mode to play music, only the game low latency mode. ⑦ a. Support simultaneous connection to Dongle and a mobile phone. b. At present, Dongle connection is the main setting. If Dongle plays audio, the audio on the mobile phone cannot be played on the headset. However, if the Dongle is not playing, the headset will play the audio of the mobile phone (you need to turn off or pause the PC player (Dongle) to play the music on the mobile phone) c. Although the connection is dominated by Dongle, if a call comes from a mobile phone, it will be forced to switch to the mobile phone. After the call is finished, audio playback on Dongle will resume. d. After the headset is turned on, the Dongle will be automatically connected back. The connection between the headset and the mobile phone must be connected back through the mobile phone. e. Some mobile phones can only power on dongle when the OTG mode is turned on.
