Hi LogicProGuy,
The issue you're describing where your iPhone 16 volume drops very low after disconnecting Bluetooth headphones is a known problem that can occur with iOS. Here are several steps you can try to resolve it:
1. Forget and Re-pair Bluetooth Headphones: Go to Settings > Bluetooth, tap the (i) icon next to your JBL headphones, and select Forget This Device. Then re-pair them and test if the volume issue persists.
2. Check Sound Settings: Go to Settings > Sounds & Haptics. Make sure the volume slider is set to your preferred level. Also check if Headphone Safety is enabled under Settings > Sounds & Haptics > Headphone Safety, as this feature can automatically reduce loud sounds.
3. Disable Reduce Loud Sounds: If Headphone Safety is on, try turning off Reduce Loud Sounds temporarily to see if it resolves the low volume issue after disconnecting headphones.
4. Restart Your iPhone: A simple restart can often resolve temporary audio routing issues. Hold the side button and either volume button, then slide to power off. Turn it back on after 30 seconds.
5. Check for iOS Updates: Even though you're on iOS 26.4.1, make sure you're on the latest version by going to Settings > General > Software Update.
6. Reset All Settings: Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This will not delete your data but will reset all system settings to default, which may fix audio routing issues.
7. Check Accessibility Settings: Go to Settings > Accessibility > Audio/Visual and make sure Phone Noise Cancellation is turned on. Also check Balance is set to center.
8. Turn Off Attention Aware Features: Go to Settings > Face ID & Passcode and turn off Attention Aware Features, as this can sometimes affect volume behavior.
9. Update JBL Headphone Firmware: Check the JBL app for any firmware updates for your headphones, as outdated headphone firmware can cause compatibility issues.
10. Contact Apple Support: If none of these steps work, the issue might be hardware-related or a deeper software bug. Consider visiting an Apple Store or contacting Apple Support for further assistance.
