JBL Charge 5 Altavoz Bluetooth portátil​​ 

Our JBL Charge 4 has Connect + and Charge 5 has PartyBoost. As Bluetooth technology improves, so do our portable products, it isn't possible to connect these two models together. Our Charge 5 can be connected with other PartyBoost speakers like: Flip 5, Pulse 4, Xtreme 3, Boombox 2.-Cryssie

Thanks for your inquiry. Setting the volume and the EQ to its maximum level may pose a risk to your JBL Charge 5, particularly when playing audio that is already bass-boosted. This can lead to distortion or rattling, potentially damaging the speaker's driver. Similarly, playing louder songs with the bass set to maximum may also pose a risk. Alternatively, you can still adjust the bass in the EQ and experiment with playing loud or bass-boosted songs. However, it's important to monitor for any signs of distortion or rattling. If you encounter these issues, adjust the settings until the sound is clean and meets your expectations for a satisfying listening experience.

Thanks for your inquiry. Our GG, TL, and CS models come from different production centers i.e. different suppliers to fulfill the production capacity but the product specification should be the same. Products from different suppliers are just having different execution in the design but the quality should be identical. To know if your product is authentic or counterfeit, you may reach out to us, so we can check it for you.

This speaker does not sync with other JBL speakers. ~Jesse
