JBL Charge 4 vs Charge 5

The JBL Charge 5 is a better speaker than the JBL Charge 4. The Charge 5 has a more balanced sound profile. It's also better built and has an IP67 rating for dust and water resistance, certifying it to be dust-tight and immersible in a meter of water for 30 minutes. That said, while the Charge 5 can connect to PartyBoost-compatible JBL speakers, it can't connect to those with the Connect+ feature like its predecessor. The Charge 4 has lower latency with iOS and Android devices, though some apps compensate for latency differently, so your experience may vary.
