Short answer: the Bose Soundlink Flex. It ranks #38 of 179 medium speakers by sound quality, rated 3.8/5, at $79.99. The TOZO PA1 ranks #60, rated 3.5/5, at $39.99, $40 cheaper, which does not close the gap in sound quality.
Why pick the Bose Soundlink Flex: A small, rugged waterproof speaker that survives drops and floats, with a warm, bass forward sound for casual outdoor use. The catch: Not stereo.
The TOZO PA1 is the longer-running pick. 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 12 for the Bose Soundlink Flex. It supports AAC Bluetooth, which the Bose Soundlink Flex lacks. It has an adjustable EQ, which the Bose Soundlink Flex lacks. Watch for: Bass is limited, fading by about 52Hz.
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.
