Q1 How to pair with two sets of Bluetooth headphones or speakers?
A1 1) Set B03Pro to pairing mode (press and hold the Bluetooth button for about 5 seconds till you see red and blue light flashes alternately), set the first Bluetooth headphone/speaker to pairing mode, you'll see a solid blue on Bluetooth 1# (icon) indicator. 2) Set B03Pro to pairing mode again, then set the second Bluetooth headphone/speaker to pairing mode. you will see a solid blue on the Bluetooth 2#(icon) indicator.
Q2 What shall i do if i can not get B03Pro Bluetooth Transmitter Receiver to pair with my Bluetooth Headphones or Speakers?
A2 1) Turn off Bluetooth on all mobile phones or PC in house (Make sure your headphone or speaker is not paired with other device automatically during the process of pairing B03Pro). 2) For first time pairing, make sure the pairing distance is within 1 meter. 3) If still cannot get them paired, set both B03Pro Bluetooth Adapter and your Bluetooth headphones or speakers to factory default.
Q3 How to reset B03Pro?
A3 Restore factory default of B03Pro by pressing Bluetooth button for about 10 seconds till all indicators flash once, then it gets into pairing mode with red and blue lights flashing, pair as normally.
Q4 Why did I get voice lag when use this Low latency B03Pro adapter with my Bluetooth headphones?
A4 To achieve low latency, your receiving device is better also support function of aptX Low Latency. Or, the receiving device might use another codec (e.g. SBC, aptX), resulting in a 70-200ms audio delay which may be noticeable by some users.
Q5 Why are the Volume + / - of my B03Pro not working in TX mode, only works in RX mode?
A5 In TX mode, take optical cable as the connected audio cable, the Volume + / - on B03Pro may not work if your device does not support Audio / Video Remote Control Profile. Change the optical cable to AUX 3.5mm or RCA audio cable, the volume buttons will work.
Q6 Why is there a delay when B03Pro is connected to two aptX low-latency headphones?
A6 in TX mode, support one aptX low latency headphones only. when paired with two aptx low latency headphones, the audio code will be aptX.
Q7 After the TV is connected to 1Mii B03Pro, can my Bluetooth headphone or speaker sound simultaneously with the TV’s built-in speaker?
A7 1) For many models of TV, the built-in speakers might not work if you choose to use an external audio output device. This is a TV feature and its availability depends on your TV make and model. 2) But you can achieve simultaneous sounding function by getting a 1Mii B03Pro and wired EXTERNAL speaker, the TX mode of B03Pro has a unique function, which allows you to share the TV audio simultaneously with an Wired EXTERNAL speaker / sound bar and a pair of Bluetooth headphones.
Q8 Is it compatible with AirPods?
A8 Yes, it is compatible with AirPods, but it is INCOMPATIBLE with AirPods Pro 2nd Gen.
