Bose Soundlink Flex vs JBL Charge Essential

Last updated: October 12, 2026

Short answer: the Bose Soundlink Flex. It ranks #38 of 175 medium speakers by sound quality (rated 3.8/5) at $159 and is still sold new; the JBL Charge Essential ranks #92 (rated 3.2/5) and is discontinued, so it is only an option used. The JBL Charge Essential’s replacement, the JBL Charge Essential 3 SE, is rated 3.7/5 at $199.95.

Bose Soundlink Flex vs JBL Charge Essential

The Bose Soundlink Flex is the better-sounding, lighter pick. IP67 rated; rugged enough to survive drops from several feet and floats. At 1.3 lbs (589 g) it weighs noticeably less than the JBL Charge Essential at 1.7 lbs (770 g). It charges over USB-C rather than Micro USB. The catch: Warm sounding with overly boosted bass which drowns out midrange detail.

The JBL Charge Essential is the longer-running pick. Doubles as a power bank. It is rated for 20 hours of battery against 12 for the Bose Soundlink Flex. The tradeoff: Less clarity than the JBL Flip 4, highs rolled off.

Buy the Bose Soundlink Flex. It is rated higher for sound quality and still sold new, while the JBL Charge Essential is discontinued.
