The JBL Charge 6 is more of an upgrade than it might at first appear. It's an engaging and enjoyable portable speaker, and represents excellent value for money, even though it's pricier than the smaller Flip 7. JBL Charge 6: Two-minute reviewThe JBL Charge 6 portable wireless speaker isn’t as closely related to the outgoing JBL Charge 5 as it might first appear. No matter the color you choose, though, you’ll be in possession of a carefully designed and beautifully built portable speaker. It’s a clean and stable app that’s a cut above the sort of thing some rival portable speakers are accompanied by.
