Short answer: the Sony ULT Field 7. It ranks #59 of 98 boombox speakers by sound quality (rated 3.2/5) at $448.99 and is still sold new; the W-King H10 ranks #75 (rated 2.7/5) and is discontinued, so it is only an option used.
The Sony ULT Field 7 is the better-sounding choice. It supports LDAC Bluetooth, which the W-King H10 lacks. It links with other speakers (Party Connect up to 100 speakers), which the W-King H10 cannot. Watch for: A peak around 8kHz, and bass does not reach as deep as the top-ranked speakers.
The W-King H10 is the lighter choice. Comes with wireless microphone. At 7.1 lbs (3.2 kg) it weighs much less than the Sony ULT Field 7 at 13.9 lbs (6.3 kg). The tradeoff: Not very deep bass.
Buy the Sony ULT Field 7. It is rated higher for sound quality; the W-King H10 is no longer sold new.
Still deciding? The full Portable Bluetooth rankings cover every ranked option.
