Short answer: the Minirig 4 on measured sound quality, the Sony SRS-XB30 on price. The Minirig 4 ranks #6 of 142 medium speakers at $229.95. The Sony SRS-XB30 ranks #107 at $199, $30.95 cheaper.
What the Minirig 4 offers: Modular, can easily attach a subwoofer. Finally USB-C charging. Dynamically changes sound based on forward facing or upward facing orientation Watch for: Calls itself splash resistant and has no official water rating. App is buggy. A bit expensive. Has reliability issues more often than any other speaker
What the Sony SRS-XB30 offers: 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. 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. 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.
Buy the Minirig 4 if sound quality matters more than the price. Buy the Sony SRS-XB30 if the price matters more than sound quality.
Skip the Sony SRS-XB30 if sound quality matters to you. It ranks near the bottom of the 142 medium speakers.
