Short answer: the Onn Medium Party Speaker Gen 2, if you are buying new. The Aiwa Exos-9 ranks higher than it (#9 vs #59 of 91 boombox speakers, 4.2/5 vs 3.1/5) but is discontinued, so only consider it used; the Onn Medium Party Speaker Gen 2 is still sold new at $90.
The Aiwa Exos-9 is the better-sounding pick. It still sounds great against current models. It has an adjustable EQ, which the Onn Medium Party Speaker Gen 2 lacks. It plays in stereo from a single unit, unlike the Onn Medium Party Speaker Gen 2.
The Onn Medium Party Speaker Gen 2 is the longer-running, lighter choice. Under $100 with LED lights synced to music. It is rated for 20 hours of battery against 10 for the Aiwa Exos-9. At 11 lbs (5 kg) it weighs noticeably less than the Aiwa Exos-9 at 15.2 lbs (6.9 kg). It is rated IPX7, while the Aiwa Exos-9 has no water resistance. The catch: Lacking detail compared to the Onn Large Party Gen 2 and not as deep of bass.
Buy the Onn Medium Party Speaker Gen 2 new; the Aiwa Exos-9 is no longer sold new, so it only makes sense as a used find.
