You know its real if you have jbl charge 4 click the minus button and the bluetooth button simultaneously and onse all 5 lights turn on at the bottom then you got it if not then click the bluetooth and plus botton simultaneously and that will reset the speaker then turn it on and try again
You should be fine. Just be careful on the knob cause bass boosted songs are clipped and will overheat the speaker and or damage the amp. Using Lfm is basically absolutely pointless tho, just dont do it lol.
That mode you're using is a debug mode made for JBL to diagnose any issues with it. Listening to music with debug mode active can potentially cause damage
@@lojanebacalso1326 The speaker is breaking, stop using lfm mode. It's not meant to be used for daily use. The speaker is meant to play upper bass 50hz and more. Anything under completely destroys it.
Lfm isn't low frequency mode or bass boost..... it's the service mode.... and you can legitimately blow the woofer inside the charge 4 running in that mode.. jbl already removed it from the xtreme 2 because ppl where blowing out the drivers n over heating the logic board inside it 😆 🤣. But I will say this... the charge 4 out of all the last gen jbl speakers really went insane in "lfm" service mode... I got alot of charge 4s and charge 5s xtreme 2s and xtreme 3s and boombox 1 n 2s iv bought n collected over the yrs. And they all used to be able run lfm but now the xtreme 2s definitely won't after the update jbl locked us out of it lol 😆 but anyway the charge 4 when in that mode if you turned it up around 80% ish the woofer itself would bottom out n pop from the voice coil hitting the bottom of the motor... it's dangerous for the charge 4... the flip 5 is fine it can run it at full volume the xtreme 2 really went nuts prob why jbl stopped it.. and the boom box hit crazy too but never bottomed out.. just the charge 4 did.. all of em n I got all models / versions of the charge 4 and all would pop at high volume lol
Technically it kinda is. It enables it to play really low frequencies all the way down to 1hz. That's why people call it "Low Frequency Mode". In normal mode, it usually drops off around 50hz but with "lfm" on, it can play below that. You can even see the passive radiators moving. You can't hear anything tho cuz it's not designed to play that low. It's basically useless for listening to music cuz it just makes the bass quieter and the woofer bottoms out at max volume. It just sounds worse imo. I don't understand why people like it so much lol
