# Why does using headphones improve test audio quality?

Using headphones during interviews, and during assessments where they’re permitted, helps improve audio clarity, reduce background noise, and prevent common sound-related disruptions.

This article explains how headphones enhance audio performance and what you can do to ensure the best possible setup before starting your session.

## ✅ 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.
