Verdict

The Sony SRS-XB402M is a rugged, portable wireless smart speaker featuring two 53mm angled full-range drivers, dual passive radiators, and a 15W power consumption profile operating over a 20 Hz to 20,000 Hz frequency response range. Key characteristics include dual-band Wi-Fi (802.11a/b/g/n) and Bluetooth 4.2 connectivity with SBC/AAC codec support, integrated Amazon Alexa voice control, Spotify Connect functionality, and built-in multi-colored line and strobe lights. Pros consist of a highly durable IP67 waterproof, dustproof, rustproof, and shockproof construction, deep bass response via EXTRA BASS and LIVE SOUND modes, and a solid 12-hour rechargeable battery life. However, notable cons include the lack of a physical auxiliary (aux) input port, an older Micro-USB charging port limited to power input only, and a somewhat bulky 1,500g design.
