Short answer: both are discontinued, so this only matters if you are buying used. Used, the Sony XB23 is the better pick: it ranks #84 of 175 medium speakers by sound quality (rated 3.3/5), against #133 (rated 2.6/5) for the Sony SRS-XB30. If you want one new, the Sony ULT Field 3 replaces the Sony SRS-XB30 and is rated 3.4/5 at $208.
The Sony XB23 is the better-sounding, lighter choice. Reasonably neutral. At 1.3 lbs (580 g) it weighs much less than the Sony SRS-XB30 at 2.2 lbs (1 kg). It charges over USB-C rather than Micro USB. Watch for: Bass drops off a ton at high levels.
The Sony SRS-XB30 is the deeper-bass, longer-running option. A compact 2.2 lbs (1 kg) portable with IPX5 splash protection, aux input, LDAC/AAC support, Sony’s app, speakerphone capability, power-bank output, stereo pairing and Party Chain linking. Its bass reaches about 55Hz before falling 10dB, against 67Hz for the Sony XB23. It is rated for 24 hours of battery against 12 for the Sony XB23. It keeps a wired aux input, which the Sony XB23 lacks. Watch for: Independent lab listening rates music fidelity only fair: bass has impact but is boomy and lacks the deepest notes, while the midrange can sound hazy, muffled and grainy.
Buy the Sony XB23 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Sony ULT Field 3, which replaces the Sony SRS-XB30.

Sony SRS-XB30: $199 Discontinued eBay
Newer model: the Sony ULT Field 3, ranked higher, rated 3.4/5, released Apr 2025. See every Sony XB and ULT generation.
Pros: A compact 1kg portable with IPX5 splash protection, aux input, LDAC/AAC support, Sony’s app, speakerphone capability, power-bank output, stereo pairing and Party Chain linking. It reaches a useful 95dB maximum level and has a claimed 24-hour battery life at moderate volume, making it a convenient older outdoor option. Measured bass extension of 55Hz (-10dB).
Cons: Independent lab listening rates music fidelity only fair: bass has impact but is boomy and lacks the deepest notes, while the midrange can sound hazy, muffled and grainy. Its micro-USB charging and older Bluetooth 4.2 platform now feel dated, so it is best considered for features and used-market value rather than sound quality. Discontinued.
