Short answer: the JBL Boombox 3 Wifi. It ranks #26 of 98 boombox speakers by sound quality, rated 3.8/5, at $389.95; the Sony ULT Field 7 ranks #59, rated 3.2/5, and costs $448.99, which makes this an easy call rather than a real tradeoff.
The JBL Boombox 3 Wifi is the better-sounding, deeper-bass choice. Loudest speaker in the category. Its bass reaches about 43Hz before falling 10dB, against 52Hz for the Sony ULT Field 7. The tradeoff: Bass boosted.
Why pick the Sony ULT Field 7: It supports LDAC Bluetooth, which the JBL Boombox 3 Wifi lacks. It links with other speakers (Party Connect up to 100 speakers), which the JBL Boombox 3 Wifi cannot. It has an adjustable EQ, which the JBL Boombox 3 Wifi lacks. The catch: A peak around 8kHz, and bass does not reach as deep as the top-ranked speakers.
Buy the JBL Boombox 3 Wifi. It is rated higher for sound quality than the Sony ULT Field 7 and costs less, so only choose the other one for a particular feature it does better.
