Short answer: the Onn Medium Party Speaker Gen 2, if you are buying new. The JBL Boombox 2 ranks higher than it (#40 vs #59 of 91 boombox speakers, 3.5/5 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 JBL Boombox 2 is the better-sounding choice. 24 hour battery life (default volume); 20+ hours even at 60% volume. It plays in stereo from a single unit, unlike the Onn Medium Party Speaker Gen 2. The tradeoff: Somewhat bass heavy and boomy.
Why pick the Onn Medium Party Speaker Gen 2: Under $100 with LED lights synced to music. It has a microphone input for karaoke or announcements, which the JBL Boombox 2 lacks. Watch for: Lacking detail compared to the Onn Large Party Gen 2 and not as deep of bass.
Buy the Onn Medium Party Speaker Gen 2, since the JBL Boombox 2 is discontinued and only worth hunting down used.
