Short answer: the Harman Kardon Luna 2 on measured sound quality, the Tronsmart T8 on price. The Harman Kardon Luna 2 ranks #25 of 182 medium speakers, rated 4.1/5, at $199.95. The Tronsmart T8 ranks #54, rated 3.6/5, at $49.99, $149.96 cheaper.
The Harman Kardon Luna 2 is the better-sounding choice. A stylish waterproof speaker with clear, spacious mids, tight bass that stays clean at volume, and stereo pairing with a second unit. Watch for: Treble can sound bright and edgy, and it loses more output off-axis than some rivals.
The Tronsmart T8 is the longer-running choice. An affordable waterproof speaker with upward firing drivers that spread sound around, plus lights, app EQ, an aux input and stereo pairing. It is rated for 18 hours of battery against 12 for the Harman Kardon Luna 2. It keeps a wired aux input, which the Harman Kardon Luna 2 lacks. 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 2 if sound quality is the priority over the price, or the Tronsmart T8 if the price is the priority over sound quality.
