Verdict

The JBL Flip 4 is a rugged, cylindrical portable Bluetooth 4.2 speaker equipped with dual 40mm drivers delivering 2x8W output power, a frequency response of 70Hz–20kHz, and dual external passive bass radiators. Its main pros include an IPX7 waterproof rating that allows complete submersion, a 3000mAh rechargeable battery providing up to 12 hours of playtime, an integrated noise-canceling speakerphone, and JBL Connect+ technology to link over 100 compatible speakers. However, its main cons are that the audio can experience harsh treble distortion at maximum volume, it does not float in water, and it relies on an outdated Micro-USB charging port rather than USB-C.
