Short answer: the Bose Soundlink Flex for rugged portability, the Sonos Play for stereo imaging. The Flex is IP67 rated, floats and survives drops from several feet, with around 12 hours of battery at moderate volume, but it is not stereo and its overly boosted bass drowns out midrange detail. The Sonos Play spreads wide stereo off-axis yet distorts on bass-heavy tracks.
Buy the Bose Soundlink Flex. It is rated higher for sound quality than the Sonos Play and costs less, so only choose the other one for a particular feature it does better.
If battery life is a priority, the Sonos Play is rated for 24 hours versus 12 hours for the Bose Soundlink Flex.

The Two Speakers In Full
Sonos Play: $299.00 Amazon $299.00 Sonos $299.00 eBay
Pros: Genuinely wide, clean stereo dispersion off-axis thanks to the two angled tweeters, holding up from the side far better than most portables. Loudness processing keeps it sounding full-bodied at low volume. 24-hour user-replaceable battery with an included wireless charging base, IP67 waterproof and dustproof, and full Sonos WiFi multi-room with AirPlay 2 on top of Bluetooth 5.3.
Cons: Bass distorts noticeably on bass-heavy tracks at default settings, and the distortion persists even after enabling Trueplay tuning and manually pulling bass back in the app. Sounds boxy and short on clarity next to cheaper competitors.
