Most people are fixed in the first three steps.
One side is dead, quiet or uneven
Bone Conduction Headphones
Both sides are built into one unit, so there's no swap test.
- Check your balance setting. A slider off center sounds exactly like a broken side.
- iPhone: Settings → Accessibility → Audio & Visual
- Android: Settings → Accessibility → Audio adjustment
- Wipe both sides with a dry cloth.
- Charge fully and reconnect.
- Try a second device. Still uneven means it's the headphones.
