Short answer: the EarFun Uboom L. It ranks #2 of 179 medium speakers by sound quality, rated 4.6/5, at $49.79. The TOZO PA1 ranks #60, rated 3.5/5, at $39.99, $9.80 cheaper, a saving that is not big enough to make up the sound-quality gap.
The EarFun Uboom L is the better-sounding, louder option. A great value medium speaker with clear, natural sound, waterproofing, and a Video Mode that keeps audio in sync with video. Alan Ross Reviews measured it at 103dB at full volume, against 98dB for the TOZO PA1. It keeps a wired aux input, which the TOZO PA1 lacks. It plays in stereo from a single unit, unlike the TOZO PA1. Watch for: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
The TOZO PA1 is the longer-running choice. A budget water resistant speaker with very long battery life, app EQ and pairing with a second unit. It is rated for 25 hours of battery against 16 for the EarFun Uboom L. Watch for: Bass is limited, fading by about 52Hz.
Buy the EarFun Uboom L. It is rated higher for sound quality, and the $9.80 you would save on the TOZO PA1 does not close the gap.
