Short answer: the Sony ULT Field 7. It ranks #61 of 113 boombox speakers by sound quality, rated 3.2/5, at $448. The ION Pathfinder 320 ranks #100, rated 2.2/5, at $129.99, $318.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Sony ULT Field 7 is the better-sounding, lighter pick. A waterproof stereo party speaker with a 30 hour battery and karaoke mic and guitar inputs. At 13.9 lbs (6.3 kg) it weighs much less than the ION Pathfinder 320 at 22.7 lbs (10.3 kg). It is rated IP67 against IPX5 for the ION Pathfinder 320. It supports LDAC Bluetooth, which the ION Pathfinder 320 lacks. Watch for: A peak around 8kHz, and bass does not reach as deep as the top-ranked speakers.
The ION Pathfinder 320 is the longer-running choice. A wheeled party speaker with an enormous battery, splash resistance, FM radio and ports for charging phones. It is rated for 100 hours of battery against 30 for the Sony ULT Field 7. The catch: Bass is not as deep as competitors.
Buy the Sony ULT Field 7. It is rated higher for sound quality, and the $318.01 you would save on the ION Pathfinder 320 does not close the gap.
