Short answer: the Xiaomi Sound Party. It ranks #19 of 142 medium speakers by sound quality at $133.62; the Harman Kardon Luna 2 ranks #23 and costs $199.95, which makes this an easy call rather than a real tradeoff.
What the Xiaomi Sound Party offers: An unusually versatile 1.2kg outdoor speaker: IP67 dust/water protection, USB-C power-bank output, NFC pairing, lights, stereo pairing and a claimed 26-hour battery life. Several independent reviews describe a warm, generally balanced sound with clear vocals and useful bass impact when Bass Boost is off. It is also easy to carry thanks to the retractable handle. Watch for: The sound evidence is mixed rather than universally glowing. One lab review found it loud but flat and unclean with blurred treble, while others hear the Bass Boost mode as boomy upper bass that can bottom out at high volume. It is not the strongest choice for a large party: tested output is around 94dB and rivals such as the Soundcore Boom 2 play louder with deeper bass. SBC is the only Bluetooth codec and there is no aux input.
What the Harman Kardon Luna 2 offers: 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. Watch for: 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).
Buy the Xiaomi Sound Party. It ranks higher for sound quality than the Harman Kardon Luna 2 and costs less, so the other one has nothing left to offer.
If battery life is a priority, the Xiaomi Sound Party is rated for 26 hours versus 12 hours for the Harman Kardon Luna 2.
