| Echo or feedback during audio playback            | Use headphones so test audio is routed directly to your ears instead of external speakers |
| Background noise interfering with audio detection | Use headphones with a built-in microphone positioned close to your mouth                  |
| Difficulty hearing instructions or prompts        | Wear headphones to receive clearer and more consistent audio output                       |
| Delays or interruptions in audio                  | Use wired headphones to avoid Bluetooth latency or connection drops                       |
| Microphone picking up unintended sounds           | Disable external speakers and rely on headphone audio only                                |
