Short answer: the JBL Partybox Encore Essential. It ranks #8 of 113 boombox speakers by sound quality, rated 4.2/5, at $299.95; the Aiwa Exos-10 ranks #44, rated 3.5/5, and costs $399.99, which makes this an easy call rather than a real tradeoff.
The JBL Partybox Encore Essential is the better-sounding option. A compact stereo party speaker with great sound, strong output, and splash resistance for backyard parties.
The Aiwa Exos-10 is the longer-running pick. A loud party boombox with FM radio, a remote, and retro VU meters. It is rated for 12 hours of battery against 6 for the JBL Partybox Encore Essential. The catch: It lacks deep bass: even with bass maxed it rolls off around 50Hz, where the W-King X20 and Zealot boomboxes reach deeper, and it is about 2dB quieter at full volume.
Buy the JBL Partybox Encore Essential. It is rated higher for sound quality than the Aiwa Exos-10 and costs less, so only choose the other one for a particular feature it does better.
