Obviously this is the successor of JBL charge 4. Now with dual drivers: 1 mid and low centric main drivers and the newly added tweeter for high frequencies for more immerssive and sparking sound reproduction compared to JBL charge 4 with just a single driver. The sound it produces is more open and the sound separation is now clearer and cleaner. Sometimes you will just have ear-piercing highs in some songs but overall it sounds better than its predecessor.
