Our Verdict

Sony SRS-XB33

Sony SRS-XB23

The Sony SRS-XB23 and the Sony SRS-XB33 are similarly performing speakers. The SRS-XB23 is smaller and has a 360-degree design, so its soundstage is perceived as wide. However, the SRS-XB33 is better built and can get slightly louder with fewer compression artifacts. Its battery also lasts longer and it has customizable lighting, which some users may prefer.
