Short answer: the Harman Kardon Onyx Studio 7 for better sound quality, the ION Pathfinder 280 for the lower price. The Harman Kardon Onyx Studio 7 ranks #13 of 75 boombox speakers at $248.90. The ION Pathfinder 280 ranks #68 at $169.99, $78.91 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 ION Pathfinder 280 offers: A practical all-day event speaker with an exceptionally long claimed 68-hour battery, wheels, telescoping handle, FM radio, lighting and a full graphic EQ/presets. RTINGS finds it gets loud with relatively little compression, and its wide dispersion makes it a useful choice for outdoor background music or casual gatherings. Watch for: Out of the box, the midrange and treble are uneven enough to sound alternately honky and dull, and the bass does not extend as deeply as better party speakers. It is heavy, only IPX5 splash-resistant, and cannot produce a true stereo image from one cabinet. Use the EQ before judging its sound.
Buy the Harman Kardon Onyx Studio 7 when sound quality outweighs the price for you, and the ION Pathfinder 280 when the price outweighs sound quality instead.
The ION Pathfinder 280 is not a sound-quality pick. It sits near the bottom of the 75 boombox speakers; there are better options higher up.
If battery life is a priority, the ION Pathfinder 280 is rated for 100 hours versus 8 hours for the Harman Kardon Onyx Studio 7.
There is a real gap in water resistance: the ION Pathfinder 280 at IPX5 (water jets) against the Harman Kardon Onyx Studio 7, which has no water resistance.
