Short answer: the Bose Soundlink Flex. It ranks #36 of 144 medium speakers by sound quality, rated 3.8/5, at $79.99. The Tozo PA1 ranks #55, rated 3.5/5, at $39.99, $40 cheaper, which does not close the gap in sound quality.
Why pick the Bose Soundlink Flex: IP67 rated; rugged enough to survive drops from several feet and floats. The catch: Not stereo.
What the Tozo PA1 does well: Tozo PA1 uses 67mm fullrange. Watch for: Bass is limited by its 52Hz specification.
Buy the Bose Soundlink Flex. It is rated higher for sound quality, and the $40 saving on the Tozo PA1 is not enough to make up the difference.
If battery life is a priority, the Tozo PA1 is rated for 25 hours versus 12 hours for the Bose Soundlink Flex.
