Short answer: the Earfun Uboom L if sound quality matters most, the Bogasing G4 if price matters most. The Earfun Uboom L ranks #1 of 142 medium speakers at $49.79. The Bogasing G4 ranks #25 at $38.59, $11.20 cheaper.
The case for the Bogasing G4: Clear sound with punchy bass, exceptional 24-hour battery life, IPX7 waterproof, multiple sound modes for different music styles. The tradeoff: Some boosted treble that’s wavy up top.
What the Earfun Uboom L gets right: Tuned by Oluv and he knocked it out of the park. Set against that: Latency is high (400ms) without turning on low latency mode (66ms) which doesn’t work when two speakers are TWS paired.
Buy the Bogasing G4 if the price is the priority over sound quality, or the Earfun Uboom L if sound quality is the priority over the price.
There is a real battery-life gap here: the Bogasing G4 is rated for 24 hours, the Earfun Uboom L only 16 hours.

The Two Speakers In Full
Bogasing G4: $38.59 Amazon eBay
Pros: A 0.83kg travel-friendly speaker with 50W output, IPX7 protection, USB-C charging, aux and microSD playback, LC3 Bluetooth and TWS pairing. It reaches a useful 100dB maximum level and has a measured 56Hz -10dB bass point, giving it more low-end presence than many speakers of this size.
Cons: The upper treble is boosted and uneven, while the mids sit slightly behind the bass and highs, so it is not a neutral choice for vocal-focused music. It has no app or user EQ, and its Super Bass and Vocal modes offer little practical differentiation according to listening tests.

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.
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.
