JBL Boombox 4 ranking card

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