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 Flip Essential ranks #90 (rated 3.2/5) and is discontinued, so it is only an option used. The JBL Flip Essential’s replacement, the JBL Flip Essential 3 SE, is rated 3.6/5 at $113.82.
The Bose Soundlink Flex is the better-sounding option. IP67 rated; rugged enough to survive drops from several feet and floats. It links with other speakers (Bose Party mode), which the JBL Flip Essential cannot. It charges over USB-C rather than Micro USB. Watch for: Warm sounding with overly boosted bass which drowns out midrange detail.
The JBL Flip Essential is the lighter pick. A genuinely portable 1 lbs (471 g) speaker with IPX7 water resistance, a 3.5mm aux input and 16W output from two full-range drivers. At 1 lbs (471 g) it weighs noticeably less than the Bose Soundlink Flex at 1.3 lbs (589 g). It keeps a wired aux input, which the Bose Soundlink Flex lacks. The catch: Bass is lighter than the JBL Flip 5 and the 80Hz claimed low-frequency limit means it cannot deliver real low-end weight.
Buy the Bose Soundlink Flex. It is rated higher for sound quality and still sold new, while the JBL Flip Essential is discontinued.

JBL Flip Essential: $130 Discontinued eBay
Newer model: the JBL Flip Essential 3 SE, ranked higher, estimated 3.6/5, released Apr 2026. See every JBL Flip Essential generation.
Pros: A genuinely portable 471g speaker with IPX7 water resistance, a 3.5mm aux input and 16W output from two full-range drivers. It is a simple, no-app option for wired sources, travel and casual listening where its cylindrical shape and modest size are a genuine advantage.
Cons: Bass is lighter than the JBL Flip 5 and the 80Hz claimed low-frequency limit means it cannot deliver real low-end weight. Battery life is only a claimed 10 hours, there is no speakerphone, EQ or party mode, and its older Bluetooth 4.1 platform and discontinued status make it a basic used-market choice.
