The Two Speakers In Full
Teufel Rockster XS: €180 Discontinued eBay
Pros: Teufel Rockster XS uses 65mm woofer + 20mm tweeter. Its 720 g, claimed 14 hours (Manufacturer specified) battery life, IPX7 protection, aux input and stereo playback make it a practical option for its intended room or portable use. A good sounding speaker for its size.
Cons: There is no companion app. No EQ adjustment. Bass does not reach as deep as others, and it was only sold in Europe. Discontinued.

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.
