Short answer: the Xiaomi Sound Party is the better buy. It ranks #19 of 157 against #25 of 157 for the Harman Kardon Luna, costs $142.99 against $290.99, and sounds more neutral than a Charge 5. The Luna is pretty balanced apart from boosted bass, but it is not stereo and less detailed than higher ranked speakers, while the Xiaomi’s bass can turn thuddy at high volume with a 180Hz peak.

The Two Speakers In Full

Xiaomi Sound Party: $142.99 Amazon eBay

Xiaomi Sound Party ranking card

Pros: 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. Measured bass extension of 54Hz (-10dB).

Cons: 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.

Harman Kardon Luna: $290.99 Amazon eBay

Harman Kardon Luna ranking card

Newer model: the Harman Kardon Luna 2, ranked higher, rated 4.1/5.

Pros: Harman Kardon Luna uses 48mm x 90mm woofer, 20mm tweeter. Its 1.13 kg, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. The sound is fairly balanced apart from the boosted bass. Measured bass extension of 57Hz (-10dB).

Cons: Bass is limited by its 57Hz specification. There is no companion app. No EQ adjustment. Boosted bass, and less detailed than higher-ranked speakers.
