Short answer: the Bose Soundlink Flex 2nd gen. It ranks #37 of 175 medium speakers by sound quality (rated 3.8/5) at $99.99 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 2nd gen is the better-sounding option. A very portable 1.3 lbs (586 g), IP67-rated speaker with a clear, well-balanced midrange that keeps voices and instruments intelligible. It supports aptX Adaptive Bluetooth, which the JBL Flip Essential lacks. It links with other speakers (Bose Party mode), which the JBL Flip Essential cannot. It has an adjustable EQ, which the JBL Flip Essential lacks. Watch for: One Flex remains mono and cannot deliver genuine low-bass rumble; RTINGS also found the elevated treble can turn hi-hats and other high-frequency detail piercing.
The case for the JBL Flip Essential: 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. It keeps a wired aux input, which the Bose Soundlink Flex 2nd gen lacks. The tradeoff: 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 2nd gen. It is rated higher for sound quality; the JBL Flip Essential is no longer sold new.

The Two Speakers In Full
Bose Soundlink Flex 2nd gen: $99.99 Amazon $99.99 eBay
Older model: the Bose Soundlink Flex (ranked lower, rated 3.8/5). See every Bose SoundLink Flex, Micro, Max and Plus generation.
Same family: the Bose SoundLink Max (larger model, rated 4.3/5), the Bose Soundlink Micro 2 (larger model, rated 3.6/5) and the Bose SoundLink Plus (larger model, rated 4.2/5).
Pros: A very portable 586g, IP67-rated speaker with a clear, well-balanced midrange that keeps voices and instruments intelligible. The second generation adds a Bose app with 3-band EQ, better-placed controls and stereo pairing with another Bose Soundlink Flex 2nd gen. It supports AAC and aptX Adaptive in addition to SBC, making it a stronger wireless option than most small rivals.
Cons: One Flex remains mono and cannot deliver genuine low-bass rumble; RTINGS also found the elevated treble can turn hi-hats and other high-frequency detail piercing. The claimed battery life is only 12 hours, and some owners report accelerated standby drain after firmware updates. It is expensive for its size, so the added app and codec support, not a transformational sound upgrade over the original, are the main reasons to choose it.

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.
