JBL Flip 4 Secrets!!

Today I'll be showing you the secrets of the JBL flip 4, like how to check your firmware version and how to make the sound quieter.
Low frequency mode won't be showed in this video, I do not recommend putting your JBL into LFM ( Low Frequency Mode ), it can damage your speaker until it's fully blown ( not working ).
