JBL Go 4 is an ultra-compact portable Bluetooth speaker designed for music, travel and everyday entertainment. Its combination of small size, rugged construction and improved sound makes it particularly convenient for seafarers who want a speaker that takes almost no space in luggage or a cabin.
The speaker delivers 4.2W RMS JBL Pro Sound through a 45 mm driver, with enhanced bass despite its compact dimensions. Bluetooth 5.3 provides wireless connectivity, while Auracast allows two Go 4 speakers to be paired for stereo sound or multiple compatible JBL speakers to be connected together. Sound can also be customised through the JBL Portable app.
Battery life is rated at up to 7 hours, with Playtime Boost adding up to 2 additional hours. The IP67 waterproof and dustproof rating makes it suitable for travel, outdoor use and maritime environments. At only 9.4 × 7.8 × 4.2 cm and approximately 190 g, it is extremely easy to pack for crew changes, flights and shore leave.
