JBL JR 300 – On-Earheadphones for Kids – Red : Product Description
Bluetooth is a wireless communication standard. Compatible devices can exchange data without connecting cables. The valid range is about 10m. Because it is an international standard, any compatible device can be connected by any manufacturer in each country.
A person who says, “I can’t get right to the point …” may be more natural to understand if you listen to the examples. For example, imagine a Bluetooth earphone.
Until now, earphones were designed to insert the end of a cable into a smartphone or PC. However, if you connect a Bluetooth-compatible headset to your smartphone, you don’t need a rope. To wirelessly transmit music data from smartphones to earphones, Bluetooth earphones can also be used in independent shapes like earplugs.
When the smartphone is connected to the car audio system, the sound may be interrupted.
It is necessary to check whether there is any problem with the smartphone or car audio used. Still, it can be solved by ” clearing the cache” (for Android) with the smartphone or “deleting device information” on the setting screen In some cases.
In some cases, the file cached by the device OS update may be damaged, and the Bluetooth connection may not be appropriately established.
In that case, clearing the cache will remove the offending file, recreate the correct folder, and ensure a successful Bluetooth connection between your smartphone and car audio.
1. Start pairing
First, operate the buttons on the Bluetooth earphone side to start matching.
The operation method differs depending on the earphone or speaker, so check the manual.
* Playing and stopping, power and volume are nothing, but you may start pairing by pressing and holding a relevant button.
2. Add device
Open “Devices and Printers” in Control Panel, and click “Add Device.”
Many people drop out without finding this. Now, click on this to start searching for devices.
When the Bluetooth earphone is detected automatically, the device installation will begin.
Windows now recognize the Bluetooth earphone as a playback device.
3. Priority output for Bluetooth earphones
However, with this alone, you will not be able to hear the sound from the Bluetooth earphone. As before, you will get out of the speaker.
This is because the speaker you have been using has priority over Bluetooth as the output destination.
Go to “Control Panel”-> “Sound,” right-click the icon that says “Bluetooth Audio Device,” and try “Set as Default Device.”
With this setting, the sound of the Windows PC will be played from the Bluetooth earphone, but no sound will be output from the speaker.
Here, when you turn off the Bluetooth earphone, it automatically switches to output from the speaker.
Also, when you turn on the Bluetooth earphone again, the output to the Bluetooth earphone has priority still, and the sound output from the speaker stops.
