Short answer: the Ruimatech RM-10. Both are rated 3.8/5 for sound quality (#29 and #26 of 113 boombox speakers), and the Ruimatech RM-10 costs $159.99 against $389.95 for the JBL Boombox 3 Wifi, so with nothing between them on sound quality, price settles it.
In a side by side sound test the JBL Boombox 3 Wifi went deeper with a more rumbling, enveloping bass. The Ruimatech RM-10 sounded punchier and more hi-fi, with clearer vocals and preferable midrange and treble while still carrying a decent amount of deep bass.
The JBL adds Wi-Fi streaming and the JBL One app, where you can adjust its midrange, and it is a sturdier, more premium build with IP67 protection. The RM-10 has no app, but it charges phones over USB-C and supports stereo pairing.
Choose the Boombox 3 Wifi for the deepest rumble, Wi-Fi and app control. Choose the RM-10 if clarity matters more than the last bit of low bass.
Buy the Ruimatech RM-10. Both are rated the same for sound quality, and it costs $229.96 less than the JBL Boombox 3 Wifi.
If battery life is a priority, the JBL Boombox 3 Wifi is rated for 24 hours versus 14 hours for the Ruimatech RM-10.
