JBL Boombox 4 vs Onn Medium Party Speaker Gen 2

Last updated: October 1, 2026

Short answer: the JBL Boombox 4 for output and tuning; the Onn Medium Party Speaker Gen 2 for a budget party box. The JBL has pretty insane output for its size with a 7-band EQ, but it is overpriced, sounds worse than the Boombox 3 out of the box and drops the aux input. The Onn costs $90 with thunderous bass and LED lights synced to music, but it lacks detail next to the Onn Large Party Gen 2 and its bass is not as deep.

Older models: the JBL Boombox 3 (ranked lower, rated 3.8/5), the JBL Boombox 2 (ranked lower, rated 3.5/5) and the JBL Boombox (ranked lower, rated 2.9/5).

Pros: Pretty insane output capability for the size. IP68 protection and Auracast pairing with other current JBL speakers. Measured bass extension of 41Hz (-10dB).

Cons: Pretty overpriced for the category. Better than the Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned. Try Oluv’s EQ for it. Out of the box sounds worse than the Boombox 3. No Aux input.
