Short answer: the Harman Kardon Luna. It ranks #26 of 175 medium speakers by sound quality (rated 4.0/5) at $290.99 and is still sold new; the Tribit Stormbox ranks #119 (rated 2.8/5) and is discontinued, so it is only an option used. The Tribit Stormbox’s replacement, the Tribit Stormbox 2, is rated 3.0/5 at $69.99.
The Harman Kardon Luna is the better-sounding choice. The sound is fairly balanced apart from the boosted bass. Watch for: Boosted bass, and less detailed than higher-ranked speakers.
The Tribit Stormbox is the longer-running, lighter choice. IPX7 water resistant, dual pairing for stereo setup, excellent battery life (20 hours), instant on/off buttons, 97dB max volume. It is rated for 20 hours of battery against 12 for the Harman Kardon Luna. At 1.2 lbs (535 g) it weighs much less than the Harman Kardon Luna at 2.5 lbs (1.13 kg). It keeps a wired aux input, which the Harman Kardon Luna lacks. The catch: Muffled sounding, treble dips from 5kHz-12kHz.
Buy the Harman Kardon Luna. It is rated higher for sound quality and still sold new, while the Tribit Stormbox is discontinued.

Tribit Stormbox: $68 Discontinued eBay
Newer model: the Tribit Stormbox 2, ranked higher, rated 3/5, released May 2024. It adds app control, adjustable EQ and AAC. Battery life goes from 20 to 24 hours. See every Tribit Stormbox and Stormbox 2 generation.
Pros: IPX7 water resistant, dual pairing for stereo setup, excellent battery life (20 hours), instant on/off buttons, 97dB max volume. Measured bass extension of 52Hz (-10dB).
Cons: Muffled sounding, treble dips from 5kHz-12kHz. Listening from the front is the worst frequency response, lay it down facing up with xbass off for the smoothest response. Not technically a 360 speaker, only front and rear. Discontinued; Tribit has retired it, superseded by the Tribit Stormbox 2.
