Short answer: the Earfun Uboom L. It ranks #1 of 142 medium speakers by sound quality at $49.79; the Soundcore 3/Soundcore Select 2 ranks #57 and costs $49.99, which makes this an easy call rather than a real tradeoff.
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 Soundcore 3/Soundcore Select 2 offers: Soundcore 3/Soundcore Select 2 uses 2x 38mm (1.5”) titanium diaphragm full-range drivers + 2x passive radiators. Its 372 g, claimed 24 hours (Manufacturer specified) battery life, IPX7 protection, up to 99dB and stereo playback make it a practical option for its intended room or portable use. Watch for: Bass is limited by its 60Hz specification.
Buy the Earfun Uboom L. It ranks higher for sound quality than the Soundcore 3/Soundcore Select 2 and costs less, which settles it without a real tradeoff to make.
Battery life favors the Soundcore 3/Soundcore Select 2: 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.
