Short answer: the Bose Soundlink Flex. It ranks #36 of 150 medium speakers by sound quality, rated 3.8/5, at $79.99. The Ortizan X10 ranks #134, rated 2.2/5, at $29.97, $50.02 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the Bose Soundlink Flex does well: IP67 rated; rugged enough to survive drops from several feet and floats. The catch: Not stereo.
Why pick the Ortizan X10: IPX7 rated and pairs with a second X10 for stereo (TWS). The catch: Not much bass, very rolled off treble.
Buy the Bose Soundlink Flex. It is rated higher for sound quality, and the $50.02 saving on the Ortizan X10 is not enough to make up the difference.
Battery life favors the Ortizan X10: rated for 30 hours against 12 hours for the Bose Soundlink Flex.
