Verdict

The JBL Go 4 is an ultra-portable Bluetooth 5.3 speaker delivering 4.2W RMS output power with a frequency response of 90 Hz to 20 kHz. Weighing just 190 grams and measuring 9.4 x 7.8 x 4.2 cm, it features a rugged, IP67 waterproof and dustproof design, an integrated carrying loop, and multi-speaker Auracast connectivity alongside JBL Portable app support with a 5-band custom EQ. Its main advantages include a highly pocketable form factor, surprisingly loud audio for its size, and a 7-hour battery life that can be extended by up to 2 hours using the Playtime Boost feature. However, its notable drawbacks include a lack of deep sub-bass due to the absence of a passive radiator, noticeable audio compression at maximum volumes, no built-in microphone for speakerphone functionality, and an inability to pair wirelessly with older-generation JBL models.
