| Q1 | What shall i do if i can not get B03Pro+ Bluetooth Adapter to pair with my Bluetooth Headphones or Speakers? |
|---|---|
| A1 | 1) Turn off Bluetooth on all phones/PC/TV in house (Make sure your headphone/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+ and your Bluetooth headphone/speaker to factory default. |
| Q2 | How to reset B03 Pro+? |
| A2 | Please press and hold the volume up and down buttons at the same time until the screen displays “Factory Settings”. |
| Q3 | Why is there still audio delay when I use this Low Latency B03Pro+ adapter with my Bluetooth headphones? |
| A3 | 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. |
| Q4 | Why are the Volume + / - of my B03Pro+ not working in TX mode, only works in RX mode? |
| A4 | 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 works. |
| Q5 | After the TV is connected to 1Mii B03Pro+, can my Bluetooth headphone or speaker sound simultaneously with the TV’s built-in speaker? |
| A5 | 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. |
| Q6 | Is it compatible with AirPods? |
| A6 | Yes, it is compatible with AirPods, but it is INCOMPATIBLE with AirPods Pro 2nd Gen. |
| Q7 | Why doesn’t LDAC mode work properly on my B03Pro+? |
| A7 | 1.Transmitter Mode (TX): 1)The paired Bluetooth device must support LDAC. 2)Switch the toggle on the left side of the B03Pro+ to LDAC. 3)LDAC does not support dual connections. If two devices are paired, it will automatically downgrade to aptX or SBC, depending on the lower codec supported.2. Receiver Mode (RX): 1)The paired device must support LDAC (Apple devices do not). 2)Some Android phones may not enable LDAC by default; it needs to be turned on in the Developer Options. |
