The sixth generation of JBL's Flip offers a number of improvements under the hood, making it a great upgrade to one of the most popular Bluetooth speakers. Similar to the Flip 5, but with improved build quality including silicone rubber mounts, it features two drive units – a racetrack woofer/midrange driver and a new tweeter – and two passive radiators for deep bass. With a built-in power of 30W, its rechargeable 4800mAh battery is said to provide up to 12 hours of music playback. The Bluetooth specification has been updated to v5.1, and the water/dust protection meets the IP67 standard. Add in full control of the Flip 6's audio parameters with the dedicated JBL app, and what more could you ask for in an affordable, portable Bluetooth speaker?
