Headphones Not Working: Step-by-Step Fixes for Windows, Mac and Phone

Updated: June 2026

Quick answer: Headphones that produce no sound are almost always a wrong default audio output, a driver issue, or — for wireless — a pairing problem. On Windows: Settings → System → Sound and pick your headphones in the output dropdown. On macOS: System Settings → Sound → Output. On phones: pull down the Quick Settings panel and tap the audio output icon to switch device.

TL;DR — Six things to try in order

  1. Check default output device. 90 % of "no sound" issues end here.
  2. Reconnect wireless. For Bluetooth: forget + re-pair. For 2.4 GHz dongle: unplug and replug.
  3. Reset volume. System mute, app mute and the hardware mute switch on the headphones themselves.
  4. Try a different audio app. If music plays but calls don't, the call app has the wrong device selected.
  5. Plug into another device. Phone gives a working ear quickly.
  6. Reinstall driver / restart audio service. Last resort before suspecting hardware.

Why headphones suddenly go silent

Three software stacks decide which device plays sound: the OS audio service, the app's own output picker, and the headphones' on-device controls. When any one drifts out of sync, sound disappears. Hardware actually fails far less often than software gets confused.

Detailed Guide — by OS

Windows 10 / 11

  1. Click the speaker icon in the taskbar → click the > arrow → pick the right output.
  2. If your device is missing: Settings → System → Sound → Volume mixer → choose per-app output.
  3. Right-click the speaker → Open Sound Settings → Troubleshoot.
  4. For Bluetooth: Settings → Bluetooth & devices → remove the headphones, then re-pair.
  5. Driver reset: Device Manager → Sound, video and game controllers → right-click your audio device → Uninstall device → reboot.

macOS

  1. Click the volume icon in the menu bar → pick your output.
  2. Or: System Settings → Sound → Output → select your headphones.
  3. If muted from the OS: check sliders for Output and Input separately.
  4. For Bluetooth that won't connect: System Settings → Bluetooth → forget the device → restart Mac → re-pair.
  5. If only one ear works on Bluetooth: open Audio MIDI Setup → check balance slider sits in centre.

iPhone / iPad

  1. Open Control Center → tap the AirPlay icon in the audio widget → choose the headphones.
  2. Settings → Bluetooth → tap the (i) next to the headphones → Forget This Device → re-pair.
  3. Try a hard reset of the headphones (button hold per the manual).
  4. Make sure Focus modes are not silencing audio — Settings → Focus.

Android

  1. Quick Settings panel → tap the speaker output icon → switch device.
  2. Settings → Connected devices → Bluetooth → forget and re-pair.
  3. Some phones (Samsung) have separate "Media volume" and "Call volume" sliders — check both.
  4. Developer Options → enable "Disable absolute volume" if Bluetooth volume is stuck at maximum.

Universal: physical issues

  • 3.5 mm jack: bent, dirty or damaged. Try a different cable or device.
  • USB-C audio: not every USB-C port supports analog passthrough. Some need a DAC adapter.
  • Bluetooth out of range: walls cut Bluetooth range to 5–10 m indoors.
  • Battery dead on wireless cans — basic but easily missed.

FAQ

I hear sound in YouTube but not Zoom.
Different apps remember different default devices. Inside Zoom: Settings → Audio → Speaker dropdown.

Bluetooth connects but no sound plays.
Check that the phone or PC is sending media (not just phone-call audio) to the device. Some Bluetooth headsets default to call-only profile.

One ear is much quieter.
Check the L/R balance slider in OS audio settings. Often slid accidentally.

Sound stops every few minutes on Bluetooth.
Wi-Fi 2.4 GHz interferes with Bluetooth. Switch your router to 5 GHz or change Bluetooth channel.

Wired works, Bluetooth not.
Driver corruption. Reinstall the Bluetooth driver from the laptop maker's website.

Key Takeaways

  • The default output device is the first thing to check — it's almost always the culprit.
  • Bluetooth: forget + re-pair fixes most pairing weirdness.
  • Apps remember their own audio device — set it inside Zoom, Teams, Spotify separately.
  • Test on a phone with the same cable to rule out the headphones themselves.
