| Q1 | Why the voice lag still here when use this Low latency ML300 Bluetooth adapter with my Bluetooth headphones? |
|---|---|
| A1 | To achieve low latency, your Bluetooth headphones/speaker should 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. |
| Q2 | What shall I do if I can not get ML300 Bluetooth Adapter to pair with my Bluetooth Headphones or Speakers? |
| A2 | Turn off Bluetooth on all mobile phones or PC in house (Make sure your headphones/speaker is not paired with other device automatically during the process of pairing ML300). For first time pairing, make sure the pairing distance is within 1 meter. If still cannot get them paired, set both ML300 Bluetooth Adapter and your Bluetooth headphones or speakers to factory default. - Reset ML300: Long press the Bluetooth button #1 for about 7 seconds until the light flash white for 3 times. |
| Q3 | Can it be used for guitar or piano? |
| A3 | For live music or musical instruments like guitar or piano, we don't suggest using ML300, please use the specialized adapter. |
| Q4 | How to change the audio codec? |
| A4 | Please double-click the Bluetooth button #1 to cycle change to different audio codecs. SBC(blue)/aptX Low Latency(white)/aptX HD(green)/aptX Adaptive(Yellow). Note: If your Bluetooth device does not support aptX Low Latency/aptX HD/aptX Adaptive, the light on ML300 will not change to the specific colour to use the aptX Low Latency/aptX HD/aptX Adaptive audio codec. |
| Q5 | Is it compatible with AirPods? |
| A5 | Yes, it is compatible with AirPods, but it is INCOMPATIBLE with AirPods Pro 2nd Gen. |
| Q6 | Does it support online calls or conference with a headset? |
| A6 | 1Mii ML300 doesn’t have a built-in mic, so it doesn't support any online calls or conference with a headset. |
| Q7 | Does it work with any TV? |
| A7 | Please make sure your TV has 3.5mm AUX AUDIO OUT jack or Headphone jack or 2RCA AUDIO OUT jack. |
