Short answer: the Sony ULT Field 3 for better sound quality, the W-King D8 Mini for the lower price, though neither ranks well in its class. The Sony SRS-XB30 measures as well as the W-King D8 Mini (#133 vs #135 of 175 medium speakers) but is discontinued. Its replacement, the Sony ULT Field 3, is rated 3.4/5 at $208; the W-King D8 Mini is rated 2.6/5 at $49.99, $158.01 cheaper. Both are rated below 3.0/5 among the 175 medium speakers, and the EarFun Uboom L, ranked #2 at $49.79, is a better place to start if sound quality matters.
The Sony SRS-XB30 is the deeper-bass, lighter choice. 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 63Hz for the W-King D8 Mini. At 2.2 lbs (1 kg) it weighs noticeably less than the W-King D8 Mini at 2.8 lbs (1.26 kg). 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.
What the W-King D8 Mini does well: 30W output with switchable indoor/outdoor EQ modes. It charges over USB-C rather than Micro USB. The tradeoff: Recessed midrange, harsh treble.
Buy the W-King D8 Mini if price matters most. For better sound quality, the Sony ULT Field 3, the replacement for the discontinued Sony SRS-XB30, is rated higher but costs $208.

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.
