Connecting the headphone to the laptop only charges it, you still have to pair it to the laptop (read the instructions that came with the headphone - and Bluetooth instructions for the laptop). Just plugging the headphone into the laptop doesn't change where the laptop audio goes. (Having the headphone paired and connected
via Bluetooth changes it, whether the headphone is plugged in or not. It's not a "Bluetooth or plugin" headphone, it's a Bluetooth headphone, with a connection
for charging only.)
From the manual:
The indicator lights up in red, and charging starts. When charging is complete, the indicator goes out.
- When the remaining battery power is low, the indicator flashes red slowly and the alarm sounds every
4 minutes.
- Operation is not possible while charging.
For pairing:
When the power is off, hold the POWER button down (for at least 7 seconds) until the indicator flashes
alternately in red and blue.
Select "JVC HA-S30BT" from the device list. The indicator flashes in blue
when pairing is complete. During the pairing process, the other device may require input of a PIN code. In such case, enter "0000" as the PIN code for the System.
What you do on the phone or laptop depends on the phone or the laptop.
