Short answer: the W-King H330. Both are rated 3.8/5 for sound quality (#32 and #29 of 113 boombox speakers), and the W-King H330 costs $95.99 against $159.99 for the Ruimatech RM-10, and with sound quality even, the cheaper one is the better buy.
Why pick the W-King H330: An affordable boombox with deep, full bass for its size, clean vocals, and fast USB-C charging. The tradeoff: It isn’t very loud, and the W-King X20S plays louder with punchier bass.
The Ruimatech RM-10 is the longer-running option. An affordable three-way boombox with clear sound that holds up at full volume, water resistance and fast charging. It is rated for 14 hours of battery against 9 for the W-King H330. Watch for: It is tuned bass boosted, much like the JBL Boombox 3.
Buy the W-King H330. Both are rated the same for sound quality, and it costs $64 less than the Ruimatech RM-10.
