Short answer: the Harman Kardon Luna for better sound quality, the Xdobo X8 for the lower price. The Harman Kardon Luna ranks #24 of 142 medium speakers at $290.99. The Xdobo X8 ranks #125 at $35, $255.99 cheaper.
What the Harman Kardon Luna offers: 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. Watch for: Bass is limited by its 57Hz specification. There is no companion app. No EQ adjustment.
What the Xdobo X8 offers: A compact 860g speaker with a useful practical feature set: IPX5 splash resistance, USB-C charging, aux and microSD playback, speakerphone and TWS pairing. Reviews consistently find it surprisingly loud and full-bodied for the size, making it a plausible inexpensive outdoor/background-music option. Watch for: The single full-range driver is the limitation. Reviews note a harsh midrange, rolled-off treble and audible distortion, while bass extension is only about 65Hz. It can play loud, but it does not have the clarity or control for attentive listening.
Buy the Harman Kardon Luna when sound quality outweighs the price for you, and the Xdobo X8 when the price outweighs sound quality instead.
Skip the Xdobo X8 if sound quality matters to you. It ranks near the bottom of the 142 medium speakers.
