Short answer: the JBL Partybox Encore 2. It ranks #4 of 113 boombox speakers by sound quality, rated 4.4/5, at $330; 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 2 is the better-sounding choice. A compact karaoke party speaker with two wireless mics, better balanced sound than the original and a long battery. The tradeoff: It still lacks some upper-bass punch and cannot match the scale of the larger PartyBoxes.
The case for the Aiwa Exos-10: A loud party boombox with FM radio, a remote, and retro VU meters. 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 2. It is rated higher for sound quality than the Aiwa Exos-10 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
