Short answer: the Earfun Uboom L. It ranks #1 of 142 medium speakers by sound quality at $49.79; the Sony SRS-XB30 ranks #107 and costs $199, so there is not much of a tradeoff to weigh.
What the Earfun Uboom L offers: One of the strongest small-speaker values for music: reviews praise clear vocals, a natural overall balance and a genuinely convincing stereo image when two are paired. IP67 protection, indoor/outdoor sound modes and Video Mode make it unusually adaptable; Video Mode substantially improves lip-sync for a single speaker. Watch for: It cannot produce real low-bass rumble or fill a large, noisy space, and RTINGS finds the top end loses detail. Low-latency Video Mode disables stereo pairing, so a two-speaker setup is not a good movie system. Firmware and app behavior have also varied over the model’s long life, and the physical controls can be easy to trigger in a bag.
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 Earfun Uboom L. It ranks higher for sound quality than the Sony SRS-XB30 and costs less, which settles it without a real tradeoff to make.
Skip the Sony SRS-XB30 if sound quality matters to you. It ranks near the bottom of the 142 medium speakers.
Battery life favors the Sony SRS-XB30: rated for 24 hours against 16 hours for the Earfun Uboom L.

Earfun Uboom L: $49.79 after coupon UBOOMLWC Amazon Myearfun eBay
Pros: One of the strongest small-speaker values for music: reviews praise clear vocals, a natural overall balance and a genuinely convincing stereo image when two are paired. IP67 protection, indoor/outdoor sound modes and Video Mode make it unusually adaptable; Video Mode substantially improves lip-sync for a single speaker. Measured bass extension of 56Hz (-10dB).
Cons: It cannot produce real low-bass rumble or fill a large, noisy space, and RTINGS finds the top end loses detail. Low-latency Video Mode disables stereo pairing, so a two-speaker setup is not a good movie system. Firmware and app behavior have also varied over the model’s long life, and the physical controls can be easy to trigger in a bag.
Setup: Try setting up the Earfun App (Android or iOS) to see if that works. If not, you’ll need to flash firmware 1.2.7 to work with the app and set with Oluv’s EQ in the Earfun app which sounds the best. The instructions say that you need a USB3 cable, but most USB2 cables work just fine, try the one included with your phone. Check the current firmware version by turning it on, then pressing the power and Bluetooth buttons at the same time. To flash, turn the speaker off then hold down the Bluetooth button while plugging in the cable. To flash on a mac, see these instructions. In TWS mode, long press the outdoor button for 2 seconds to change TWS to Party mode and back.
