Short answer: the Harman Kardon Onyx Studio 7 if sound quality matters most, the Onn Medium Party Speaker Gen 2 if price matters most. The Harman Kardon Onyx Studio 7 ranks #13 of 75 boombox speakers at $248.90. The Onn Medium Party Speaker Gen 2 ranks #45 at $90, $158.90 cheaper.
What the Harman Kardon Onyx Studio 7 offers: The addition of dual tweeters gives the Studio 7 a wider, more spacious presentation than older Onyx models. It delivers strong, deep bass, useful large-room volume and can pair with a second Studio 7 for stereo. Watch for: Consumer Reports finds the bass prominent and boomy, mids hazy, treble slightly smeared and the soundstage congested. Battery life remains only about eight hours, it has no water rating or advanced codecs, and it is not an especially loud outdoor speaker.
What the Onn Medium Party Speaker Gen 2 offers: Under $100 with LED lights synced to music. Simple controls, solid Bluetooth range. Mic input for karaoke/emcee. Built-in FM radio with 16 presets. Aux port. Watch for: Lacking detail compared to the Onn Large Party Gen 2 and not as deep of bass. Only available in the United States and Canada.
Buy the Harman Kardon Onyx Studio 7 if sound quality is the priority over the price, or the Onn Medium Party Speaker Gen 2 if the price is the priority over sound quality.
