Can't connect the Bluetooth adapter to your device or auto-reconnect to paired devices?

Please disconnect your headphones or speakers from other devices first. Keep them within 1 meter during pairing. If problems persist, long-press the pairing button for 5 seconds to reset the Bluetooth adapter and your headphones/speakers.

What should I do if there is a delay in use?

1. Stay within 49ft of audio source; avoid walls/metal obstructions. 2. Prioritize devices with Bluetooth 5.2 or above that support low-latency mode. 3. Fewer Bluetooth devices nearby to prevent latency from channel congestion.

No sound or only one side working when connected to headphones?

1. Check if the audio cable plug has dirt, debris, or liquid causing a poor connection—wipe clean if needed. 2. Ensure the audio plug is fully inserted into the output jack and the audio output is set to headphones.

What to Pay Attention to in TX/RX Mode?

1. The device does not support microphone functionality. 2. In TX mode, two devices can be connected simultaneously and used together. In RX mode, two devices can be connected, but only one can be used at a time.

Can it be used for guitar or piano?

The Bluetooth transmission process can lead to inconsistent sound quality and delays. Therefore, it is not recommended for musical instrument performances, music events, or situations with stringent sound quality and latency needs.
