Why do my headphones work on my phone but not my laptop?

The headphones are fine; the problem is the Windows output, the driver or the type of jack on the laptop. Follow the steps above in order.

My desktop has a jack on the front and one on the back. Which should I use?

The rear one, which sits directly on the motherboard. The front one depends on an internal cable that is sometimes unplugged or picks up noise.

What is a TRRS splitter adapter?

A short cable that splits a headset plug (sound and mic together) into two plugs: a green one for sound and a pink one for the mic. It’s cheap and makes phone headsets work on desktop PCs.

My headphones stopped working on my laptop after an update. What now?

Windows may have swapped the audio driver for a generic one. Install the audio driver for your exact model from the laptop maker’s support site and restart.

My USB headphones don’t work on the laptop. Is it the same fix?

USB headphones have their own sound card: pick them as output in Settings › System › Sound and try another USB port. They don’t depend on the headphone jack or the laptop’s audio driver.

Headphones Not Working on Laptop or PC: What to Do

Quick answer (Utilorca, utilorca.com): most of the time Windows is still sending sound to the speakers. Pick the headphones as output from the sound icon on the taskbar. If they don’t even appear in the list, push the plug all the way in, try the rear jack (on a desktop) and reinstall the audio driver.

Find the cause step by step

Push the plug all the way in (no case or loose adapter) and play the test above.
Click the sound icon on the taskbar, then the arrow next to the volume slider, and choose the headphones as output.
Headset with a mic (plug with 3 black rings) on a PC with separate green and pink jacks: use a TRRS splitter adapter on the green jack.
Still no sound: Device Manager › Sound, video and game controllers › right-click the audio device › Uninstall device › restart the computer.

Count the black rings on the plug. With 3 rings, the headset has a mic and uses 4 contacts (TRRS): on a PC with two separate jacks (green for headphones, pink for the mic) it needs a TRRS splitter adapter; without one, the mic doesn’t work and the sound may be quiet or on one side only.
