Welcome, everybody! Today we're thrilled to showcase some fantastic features of the JBL Charge 3 speaker. Let's dive in!

Right in. The low-frequency mode. By default, it's turned off to conserve battery and maintain sound quality.

To activate or deactivate low-frequency mode, simply press and hold the Bluetooth and volume down buttons for about 10 seconds.

Factory reset option: To perform a factory reset, press and hold the volume up and play buttons for a few seconds until the speaker turns off. When you turn it back on, it'll be like it just came out of the box, ready for a fresh start.

Then there's the alt lights mode, also known as test mode, which checks if all the lights on the speaker are functioning correctly. To enter this mode, ensure the speaker is powered on, then hold the volume down and play buttons for a few seconds until all the lights illuminate briefly.

Another handy feature is the ability to check your firmware version. Simply hold the volume down and connect plus buttons for a few seconds, and the speaker will play back its firmware version.

Lastly, there's service mode, which essentially locks the speaker from turning on until you disable service mode. This can be useful for security purposes. To activate service mode, press and hold the connect plus and volume up buttons for about 10 seconds. The speaker will shut down, and when you try to power it back on, it won't respond.

To exit service mode, repeat the button combination while the speaker is plugged in.

And that wraps up the secret features of the JBL Charge 3 speaker. We hope you found this tutorial helpful. Thanks for watching!
