JBL Flip 5 Speaker: How to Check and Manage Low Frequency Mode On/Off Status or via App

Good morning again, this time I have a problem with the JBL Flip 5 speaker - well, I don't know if I have Low Frequency Mode on or not.
How to check when I have it on and when it's off??
Or some kind of application? I don't know... Please help

Hi!
The easiest way to check if LFM (Low Frequency Mode) is on is by listening.
When you turn on the speaker, play music (e.g. bass boosted, or some bass house) and listen to the sound of the speaker.
Then you start the procedure of enabling/disabling the LFM mode (I attach a link to how to enable it: link )
After switching the mode, you play the same track again and the listener is there a noticeable change in the sound of your speaker (in the low band).
If it is - the FLM mode was turned off, if the bass is "shallower" then the FLM function has been turned off.
Kind regards

Do a hard reset of the speaker (hold the bluetooth and button)
