Third-party reviews

What customers like about Sony SRS-X55

  • Impressive sound clarity and fullness for its size
  • Strong, punchy bass output aided by a dedicated subwoofer
  • High volume ceiling that fills large rooms without major distortion
  • Sleek, classy minimalist design with intuitive touch controls
  • Quick and seamless connectivity via NFC tap-to-pair and Bluetooth
  • Doubles as a power bank via USB to charge smartphones

What customers don't like about Sony SRS-X55

  • Lacks water resistance, limiting its durability for outdoor use
  • Relatively heavy and bulky compared to newer ultra-portable models
  • Battery life decreases significantly when playing at maximum volume
  • No dedicated track navigation buttons on the device itself
  • Slightly drops in maximum loudness when running on battery instead of AC power
  • Glossy top finish is highly prone to catching fingerprints

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.
