Headphones

Step-by-step headphone and headset check when buying or for yourself. Works for new and used devices.

1

Quick check

5 minutes, no software to install

  1. Visual inspection

    Earpads intact, headband not cracked, cable without kinks or exposed wires, plug not bent.

  2. Connection

    The system recognizes the device (for USB or Bluetooth).

  3. Sound in both channels

    Play music or a video: sound must come from both left and right sides.

  4. Microphone

    If present — record your voice in the standard Voice Recorder app or test in Discord/Zoom.

2

Medium check

5–10 minutes

  1. Controls

    Test volume buttons, track switching and the Mute button (on the cable or earcup).

  2. Wireless connection

    If wireless — check Bluetooth stability and pairing with different devices (PC, phone).

  3. Backlight

    If present — test all modes.

3

Full check

10–15 minutes

  1. Frequency check

    Listen to test tracks with bass, mids and highs. No distortion at high volume.

  2. Volume stress test

    Play music at max volume: the drivers must not rattle.

  3. Balance and positioning

    In games or special tests, check that sound direction is correct (e.g. in shooters).

  4. Software

    If there is software — set the equalizer and virtual surround (7.1), check that settings save.

How to test tech before buying

Buying new or used tech always comes with risks: hidden defects, dead pixels, broken keys, a worn battery, cooling issues and other problems are not always visible during a casual inspection. FullTestPC provides detailed step-by-step guides to help you catch everything when checking devices. For each type of hardware — laptops, desktop PCs, monitors, keyboards, mice, headphones, GPUs, SSDs and HDDs, RAM, CPUs and power supplies — we have three levels of diagnostics: a quick 5–10 minute check with no software to install (visual inspection, basic functions), a medium 15–20 minute check using built-in Windows tools (battery reports, chkdsk, load tests) and a full 30–60 minute check using professional utilities like AIDA64, FurMark, CrystalDiskInfo, Victoria, TestMem5 and OCCT. This approach lets you adjust the depth of the check to the situation: a quick check is enough when buying from a store, a medium check when buying from a private seller, and a full stress test of all components for complete peace of mind. Many tests can be done right in the browser using our online tools (keyboard test, monitor dead pixel test, mouse and trackpad test), while the rest use standard or free programs. Following these checklists reduces the risk of buying a broken device and gives you confidence in its condition.
