Array Question:1 In TX mode, there will be delay when using some audio devices? Answer:1 To achieve low latency, your Bluetooth headset/speaker should also support the aptX Low Latency feature. Alternatively, the receiving device may use another codec (e.g. SBC, aptX), resulting in 70-200ms of audio latency, which may be noticeable to some users. Question:2 Can it be used for guitar or piano? Answer:2 When using professional music equipment, such as guitar, piano, etc., we recommend that you purchase dedicated equipment. Question:3 Can't connect my device? Answer:3 Please check the Bluetooth Transmitter Receiver during use to see if it is occupied (the blue light is always on). If it is occupied, please turn off other Bluetooth devices or clear the connected Bluetooth devices. Question:4 Can I make voice calls using a Bluetooth receiver in my car? Answer:4 Yes! We built in a microphone so you can answer calls with the click of a button when using it in your car. Question:5 How long can a Bluetooth Wireless Transmitter be used on a single charge? Answer:5 In RX mode, it can be used for 13 hours, and in TX mode, it can be used for 16 hours.
