Short answer: the Harman Kardon Luna on measured sound quality, the Tronsmart T8 on price. The Harman Kardon Luna ranks #24 of 150 medium speakers, rated 4.0/5, at $290.99. The Tronsmart T8 ranks #52, rated 3.6/5, at $49.99, $241 cheaper.
The case for the Harman Kardon Luna: Harman Kardon Luna uses 48mm x 90mm woofer, 20mm tweeter. The catch: Bass is limited by its 57Hz specification.
What the Tronsmart T8 does well: Two upward firing drivers, a woofer and two passive radiators spread sound evenly around the speaker, so placement matters less. The catch: Against the Xiaomi Sound Outdoor, listeners in Mateusz Cholewa’s comparison found the T8 harsh and tiring, and Techder Audios’ test showed the Xiaomi Sound Party with deeper, heavier bass.
Buy the Harman Kardon Luna when sound quality outweighs the price for you, and the Tronsmart T8 when the price outweighs sound quality instead.
Battery life favors the Tronsmart T8: rated for 18 hours against 12 hours for the Harman Kardon Luna.

The Two Speakers In Full
Harman Kardon Luna: $290.99 Amazon eBay
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.

Tronsmart T8: $49.99 Best Buy Tronsmart eBay
Pros: Two upward firing drivers, a woofer and two passive radiators spread sound evenly around the speaker, so placement matters less. In AudioPro Reviews’ and Dresser’s comparisons most listeners preferred it to the JBL Flip 6, JBL Flip 7 and Ultimate Ears Megaboom 3 for its fuller body and less fatiguing treble, and Audioreviews.org found it stayed clean at maximum volume. It is rated for 40W, with IPX7 waterproofing, an 18 hour battery rating, app EQ, lights, a volume wheel, aux input, TF card playback, a lanyard and stereo pairing.
Cons: Against the Xiaomi Sound Outdoor, listeners in Mateusz Cholewa’s comparison found the T8 harsh and tiring, and Techder Audios’ test showed the Xiaomi Sound Party with deeper, heavier bass. Josh’s Gadgets and More preferred the cheaper Vortex Blast for smoother highs and deeper bass. Bass is rated only down to 56Hz.
