Headphones & earbuds

Wired or Bluetooth headphones aren't recognized by a computer

This is usually a driver, output selection, or port issue on the computer rather than a fault with the headphones. Checking the sound output device settings first fixes most cases.

Symptoms

Likely causes

  • CommonComputer's audio output not manually switched to the headphonesPlugging in or pairing headphones doesn't always automatically change the active output device.
  • CommonOutdated or missing audio/Bluetooth driver on the computerWindows and Mac both rely on drivers to properly detect and use external audio devices.
  • PossibleFaulty or dirty headphone jack on the computerA damaged or debris-filled port can prevent proper detection.
  • PossibleUSB-C or Lightning adapter compatibility issue (for digital headphone connections)Some adapters or dongles have compatibility quirks with specific computers.
  • Less commonHeadphones' own hardware faultA failure inside the headphones' connector or Bluetooth module can prevent recognition on any device.

What to do

  1. Go to your computer's sound settings and manually select the headphones as the output device.
  2. Check Device Manager (Windows) or About This Mac > System Report (Mac) for any audio device errors and update drivers if needed.
  3. Try the headphones' jack or Bluetooth pairing on a different device (like a phone) to confirm the headphones themselves work.
  4. Clean the computer's headphone jack with a dry cotton swab or compressed air if using a wired connection.
  5. For Bluetooth, remove the pairing on the computer and pair fresh.
  6. If using a USB-C or Lightning adapter, try a different one or connect directly if the computer supports it.
  7. Restart the computer after connecting the headphones to refresh device detection.
