Short answer: the Bose Soundlink Flex. It ranks #38 of 164 medium speakers by sound quality, rated 3.8/5, at $79.99; the JBL Pulse 6 ranks #49, rated 3.7/5, and costs $329.95, so there is not much of a tradeoff to weigh.
The Bose Soundlink Flex is the lighter pick. IP67 rated; rugged enough to survive drops from several feet and floats. At 1.3 lbs (589 g) it weighs much less than the JBL Pulse 6 at 3.3 lbs (1.49 kg). The catch: Warm sounding with overly boosted bass which drowns out midrange detail.
The case for the JBL Pulse 6: A 63.8mm woofer on 30W RMS and a 16mm tweeter on 10W RMS, with JBL rating the response down to 42Hz, well below the Pulse 5’s 58Hz. It supports AAC Bluetooth, which the Bose Soundlink Flex lacks. It has an adjustable EQ, which the Bose Soundlink Flex lacks. Watch for: No independent measurements or tested reviews have been published yet, so its real bass extension, loudness and tonal balance can’t be compared with ranked speakers.
Buy the Bose Soundlink Flex. It is rated higher for sound quality than the JBL Pulse 6 and costs less, which makes it the one to get unless you need something the other one does better.

JBL Pulse 6: $329.95 Estimated Amazon eBay
Older model: the JBL Pulse 5 (ranked higher, rated 3.7/5).
Pros: A 63.8mm woofer on 30W RMS and a 16mm tweeter on 10W RMS, with JBL rating the response down to 42Hz, well below the Pulse 5’s 58Hz. IP68 makes it fully dustproof and submersible, a step up from the Pulse 5’s IP67. The 360° light show now runs over an illuminated carry handle too, with 16 themes, a double-tap bedside lamp and a Sunset Mode sleep timer in the JBL One app. Bluetooth 6.0 with SBC, AAC and LC3, lossless playback over USB-C, and Auracast for stereo pairing or linking PartyBox speakers and PartyLight Sticks.
Cons: No independent measurements or tested reviews have been published yet, so its real bass extension, loudness and tonal balance can’t be compared with ranked speakers. It plays in mono from one woofer and one tweeter, so a single unit gives no stereo separation. Battery life is rated at only 12 hours from its 34Wh pack, charging takes up to 4.5 hours, and the USB-C port can’t charge a phone. There is no strap, only the built-in handle.
