Using the provided Charger, it typically takes 3.5 hours to fully charge the JBL Xtreme 2 from 0% to 100%. However, the charging time may vary depending on the Charger’s voltage output and the device’s remaining battery level. Another issue when charging the JBL Xtreme 2 may be a loose connection between the charging cable and port. This can happen due to cable damage or a malfunctioning port. If so, try using another charging cable or port to see if the issue persists. Both speakers have JBL's PartyBoost feature too. This replaced Connect+, but does pretty much the same thing – it lets you wirelessly daisy chain up to 100 JBL speakers to create a louder, more immersive sound. Or you could just connect two for stereo. It doesn't work with older JBL speakers that offer Connect+ though, so you'll have to pair like with like. In the current line-up, PartyBoost speakers are the Xtreme 3 and Charge 5, Boombox 3 and 2, Pulse 5 and Flip 6.

The JBL Xtreme 2 is an impressive portable Bluetooth speaker with powerful sound and long battery life. However, like any electronic device, it may encounter some charging issues over time. We believe the Charge 5's sound better nails our performance-per-pound criteria, but both are excellent for their size and money. Having said that, you could be better served by the Xtreme 3 if your priorities are a louder, meatier sound, you don't mind a bigger, heavier speaker, and budget isn't an issue. You will no doubt find the carry strap (and perhaps also the integrated bottle opener) handy, and might side with the added peace of mind that a more robust build quality provides. Your choice, but know that both are winners in our eyes.

Notes' leading edges through the low end are crisper, resulting in a more agile performance, while vocals have more energy.
