Short answer: the Sony ULT Field 7 on measured sound quality, the Tronsmart Halo 200 on price. The Sony ULT Field 7 ranks #61 of 113 boombox speakers, rated 3.2/5, at $448. The Tronsmart Halo 200 ranks #76, rated 2.8/5, at $169.99, $278.01 cheaper.
The Sony ULT Field 7 is the better-sounding, longer-running pick. A waterproof stereo party speaker with a 30 hour battery and karaoke mic and guitar inputs. It is rated for 30 hours of battery against 18 for the Tronsmart Halo 200. It is rated IP67 against IPX4 for the Tronsmart Halo 200. It supports LDAC Bluetooth, which the Tronsmart Halo 200 lacks. The tradeoff: A peak around 8kHz, and bass does not reach as deep as the top-ranked speakers.
The Tronsmart Halo 200 is the deeper-bass choice. A three-way party speaker with dynamic lighting, an 18 hour battery and broadcast linking for many speakers. Its bass reaches about 44Hz before falling 10dB, against 52Hz for the Sony ULT Field 7. Watch for: Not as deep bass as some of the top ranked.
Buy the Sony ULT Field 7 when sound quality outweighs the price for you, and the Tronsmart Halo 200 when the price outweighs sound quality instead.
