Short answer: both are discontinued, so this only matters if you are buying used. Used, the JBL Charge 4 is the better pick: it ranks #63 of 175 medium speakers by sound quality (rated 3.5/5), against #133 (rated 2.6/5) for the Sony SRS-XB30. If you want one new, the JBL Charge 6 replaces the JBL Charge 4 and is rated 4.2/5 at $119.95.
The JBL Charge 4 is the better-sounding, tougher choice. Doubles as a power bank for charging phones/tablets. It is rated IPX7 against IPX5 for the Sony SRS-XB30. It charges over USB-C rather than Micro USB. The catch: 1 Oval driver.
Why pick the Sony SRS-XB30: 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. It supports LDAC Bluetooth, which the JBL Charge 4 lacks. It has an adjustable EQ, which the JBL Charge 4 lacks. It plays in stereo from a single unit, unlike the JBL Charge 4. 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 JBL Charge 4 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 JBL Charge 6, which replaces the JBL Charge 4.

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.
