Verdict

The JBL Xtreme 4 is a rugged, 2.1 kg portable Bluetooth 5.3 speaker equipped with a two-way audio system consisting of two 70mm woofers, two 20mm tweeters, and dual passive radiators that deliver up to 100W RMS of total output power on AC mode (70W RMS on battery) with a 44 Hz to 20 kHz frequency response. Key advantages include an IP67 waterproof and dustproof rating, a built-in power bank to charge mobile devices via USB-C, Auracast multi-speaker pairing, and an impressive battery life of up to 24 hours (extendable by 6 hours via Playtime Boost) with a user-replaceable battery design. However, notable drawbacks include its bulky and somewhat heavy frame, audio compression with diminished bass response at maximum volumes, the complete omission of a 3.5mm auxiliary input, and limited high-quality Bluetooth codec support restricted to basic SBC.
