Short answer: the Tribit Stormbox Flow for battery life, the JBL Flip Essential for an aux input. The Flow runs up to 30 hours of battery life, roughly double most rivals and still about 20-24 hrs with XBass on, but it is not stereo and recesses midrange and bass about 4db below 700Hz, while the Flip Essential has less bass than a Flip 5.
Buy the Tribit Stormbox Flow. It is rated higher for sound quality and still sold new, while the JBL Flip Essential is discontinued.

The Two Speakers In Full
JBL Flip Essential: $130 Discontinued eBay
Newer model: the JBL Flip Essential 2, ranked higher, rated 3.3/5.
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 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.

Tribit Stormbox Flow: $79.99 Tribit eBay
Smaller model: the Tribit Stormbox Micro 2 (rated 4.5/5).
Larger models: the Tribit Stormbox Pro (ranked higher, rated 3.7/5) and the Tribit Stormbox Blast (rated 4.5/5).
Pros: Up to 30 hours of battery life: roughly double most rivals (~20-24 hrs with XBass on). IP67 rated with a loose handle for carrying/hanging. Pairs with a second Flow for stereo; USB-C port charges your phone too. Measured bass extension of 47Hz (-10dB).
Cons: Not stereo. Midrange and bass are weirdly recessed about 4db below 700Hz. You need xbass mode for it to not sound like a clock radio with missing bass. You also can’t turn up the bass enough in the custom EQ modes to get it neutral, so it will sound bass light. Firmware 1.2.3 fixes the distortion issues with xbass mode on, but bass still sounds wobbly and uncontrolled.
