Fehlerbehebung
If you encounter issues with your eppfun AK3040Pro, please refer to the following common solutions:
- Cannot Pair or Connect:
If your headphones have been previously connected to other Bluetooth devices, their internal Bluetooth connection information might not be automatically cleared. To resolve this, you need to reset your headphones and clear any previous pairing information before attempting to match them with the AK3040Pro. This is especially common with high-end Bluetooth earphones like Apple or Beat earphones.
- Poor or Intermittent Sound Quality:
The sound quality can be affected by the audio decoding codec in use. If you experience poor or intermittent sound, try switching the audio decoding codec by pressing the button on the adapter. Ensure your headphones also support the selected codec for optimal performance. The product supports APTX/APTX LL/SBC/APTX HD/APTX adaptive.
- Duplex Mode Audio Issues (PS4/PS5):
When connected to PS4 or PS5, the adapter may automatically enter Duplex mode (game call + music), which can result in decreased music quality or sizzling noise. To return to music-only mode, double-click the button on the adapter.
