Our Verdict

Sony SRS-XG300

Ultimate Ears EPICBOOM

The Sony SRS-XG300 and the Ultimate Ears EPICBOOM each have different strengths. The Sony has a boombox-style design; this speaker also lets you pair with voice assistants from your smartphone. However, its sound quality isn't as good as that of Ultimate Ears, which has a better soundstage. Plus, the Ultimate Ears has more sound customization tools, like a room correction feature called Adaptive EQ.
