Hi Delores Ekberg,
I’m following up to see whether you were able to try the suggested steps and what happened when you attempted to pair the headphones again.
Could you confirm the exact JBL model and whether the blue light is flashing or remains solid? Please make sure the headphones are specifically in pairing mode, as simply turning them on may not make them discoverable.
If they still do not appear, open Settings > Bluetooth & devices > Devices and change Bluetooth devices discovery to Advanced, if that option is available, then try adding them again.
Please also test whether the headphones can be detected by another phone or computer and whether your laptop can detect a different Bluetooth device. This will help narrow down whether the issue is with the headphones or the laptop’s Bluetooth connection.
When you reply, please also include your Windows version and OS build by pressing Windows key + R, entering winver and selecting OK.
I look forward to your update.
