Verdict

The EarFun UBOOM L is a highly capable portable Bluetooth 5.0 speaker featuring dual 55mm drivers and dual passive radiators that deliver a combined 28W of stereo power. Weighing 650g with dimensions of 78mm x 210mm x 72mm, it excels with an IP67 waterproof and dustproof build that allows it to float, a 3.5mm auxiliary input, dedicated Indoor/Outdoor EQ modes, and a 150ms low-latency Video Mode. It packs a 7.4V (2x2600mAh) battery providing up to 16 hours of playtime via USB-C charging, offering standout pros like a neutral, Oluv-tuned audio signature, exceptional clarity, and True Wireless Stereo pairing. However, its main cons include a lack of deep low-bass extension, real-world battery performance that often falls short of the 16-hour claim at higher volumes, and an absence of a companion app or built-in voice assistants for deep sound customization.
