Short answer: the EarFun Uboom L. It ranks #2 of 177 medium speakers by sound quality, rated 4.6/5, at $49.79; the W-King D8 Mini ranks #135, rated 2.6/5, and costs $49.99, which makes this an easy call rather than a real tradeoff.
The EarFun Uboom L is the better-sounding, deeper-bass pick. A great value medium speaker with clear, natural sound, waterproofing, and a Video Mode that keeps audio in sync with video. Its bass reaches about 56Hz before falling 10dB, against 63Hz for the W-King D8 Mini. Alan Ross Reviews measured it at 103dB at full volume, against 100dB for the W-King D8 Mini. At 1.4 lbs (650 g) it weighs much less than the W-King D8 Mini at 2.8 lbs (1.26 kg). The tradeoff: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
The W-King D8 Mini is the longer-running option. An inexpensive water resistant stereo speaker with indoor and outdoor sound modes and a long rated battery. It is rated for 24 hours of battery against 16 for the EarFun Uboom L. The tradeoff: Recessed midrange, harsh treble.
Buy the EarFun Uboom L. It is rated higher for sound quality than the W-King D8 Mini and costs less, which makes it the one to get unless you need something the other one does better.
