Verdict

The Sony SRS-X55 is a compact 2.1-channel portable Bluetooth 3.0 speaker measuring 22.1 x 11.8 x 5.1 cm and weighing 1.2 kg. It delivers a powerful audio performance with 30W of total output power when plugged into AC voltage (dropping to 20W on battery power), driven by dual 38mm full-range drivers, a dedicated 58mm subwoofer, and dual passive radiators. Main pros include its surprisingly deep bass response, high-quality wireless streaming through Sony's proprietary LDAC codec, convenient NFC one-touch pairing, and a dual-purpose USB port capable of charging external mobile devices over its 10-hour battery lifespan. However, notable cons include its complete lack of water resistance or an IP rating for outdoor use, its relatively heavy build for travel, and a lack of warm midrange frequencies that leaves the audio profile feeling slightly skewed toward highs and lows.
