Short answer: the Earfun Uboom L ranks #1 of 142 medium speakers by sound quality at $49.79; the Bogasing M5 ranks #55 at $45.59. The price gap is small enough that the sound-quality ranking should decide it.
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 Bogasing M5 offers: Compact enough for a backpack side pocket at under 1.7 lb. Up to 30 hours of battery life. USB-C charging - no proprietary cable to lose. Watch for: Front/rear driver configuration. Use bass mode for the flattest response. Sounds thin in the midrange. Hot treble and rolled off bass in default mode. Treble a bit rolled off in bass mode.
Buy the Earfun Uboom L if sound quality is the priority over the price, or the Bogasing M5 if the price is the priority over sound quality.
There is a real battery-life gap here: the Bogasing M5 is rated for 30 hours, the Earfun Uboom L only 16 hours.

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.
