Short answer: the Harman Kardon Luna 2 if sound quality matters most, the Tribit Stormbox Mini+ if price matters most. The Harman Kardon Luna 2 ranks #23 of 144 medium speakers, rated 4.1/5, at $199.95. The Tribit Stormbox Mini+ ranks #115, rated 2.5/5, at $29.99, $169.96 cheaper.
Why pick the Harman Kardon Luna 2: Articulate, spacious midrange with precise imaging and instrument separation. Watch for: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
What the Tribit Stormbox Mini+ does well: IPX7 waterproof, app support with EQ presets and AAC codec, true wireless stereo (TWS) capability, USB-C charging, built-in mic for calls, AUX input, microSD card playback. The tradeoff: Not a great sounding speaker, really weak bass.
Buy the Harman Kardon Luna 2 if sound quality is the priority over the price, or the Tribit Stormbox Mini+ if the price is the priority over sound quality.

The Two Speakers In Full
Harman Kardon Luna 2: $199.95 Amazon B&H Photo Video eBay
Older model: the Harman Kardon Luna (rated 4/5).
Pros: Articulate, spacious midrange with precise imaging and instrument separation. Tight, well-controlled bass from the 62mm x 82mm woofer and passive radiator despite the compact body, and it stays cleaner at volume than pricier rivals like the Sonos Play. IP67 rated, and two units pair via AirTouch for true stereo sound.
Cons: Treble can sound bright and edgy, and it loses more output off-axis than some rivals. Some listeners hear mid-range rattling on certain tracks, similar to sibling JBL models. 12-hour battery life trails category leaders like the JBL Charge 6, which doubles it. Single unit is not stereo (1.1 driver layout).
