JBL unveiled the Flip 5 Bluetooth speaker at CES this week, with some notable enhancements over the Flip 4. The most visually-obvious thing they’ve done is moved to a waterproof USB-C connector for charging, eschewing the rubber cover that protected its predecessor’s micro-USB port. This means the Flip 5 is fully submergible without having to first check to ensure the waterproof charge cover is in place. Additionally, JBL has remodeled the acoustic design, now using a racetrack-shaped driver that should increase the speaker’s bass response. Battery life is also increased to a full 12-hours of playtime. The JBL Flip 5 will be available this spring for US$99.95.
