Why does using headphones improve test audio quality?

✅ Common causes and fixes

What might be wrong	How to fix it
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
Using headphones in a proctored exam that doesn’t permit them	Check your exam instructions. Headphones, earphones, and earbuds (wired or Bluetooth) can’t be used in proctored exams unless explicitly permitted. If they aren’t permitted, use your device’s built-in speakers and microphone

📌 Best practices -

Use wired headphones, if possible, to avoid Bluetooth lag.

Ensure mic permissions are granted for your headphones.

Avoid using gaming headsets with heavy audio processing.

Additional tips:

In proctored exams, use headphones only if your exam instructions permit them. In live and Ivy interviews, headphones are recommended.
Prefer wired headphones over Bluetooth devices to reduce lag and avoid pairing issues.
Connect your headphones before opening the test link so the browser detects them correctly.
Confirm that the correct microphone and audio output device are selected in your system settings.
Avoid gaming headsets or devices with aggressive noise cancellation or sound enhancement features.
Test audio before starting the assessment or interview.
