Short answer: the Marshall Emberton II, though neither ranks well in its class. It ranks #105 of 144 medium speakers by sound quality, rated 2.7/5, at $159.99. The Altec Lansing Lifejacket 2 ranks #143, rated 2.0/5, at $69.99, $90 cheaper, which does not close the gap in sound quality. Both are rated below 3.0/5 among the 144 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #1 at $49.79.
The case for the Marshall Emberton II: 30 hour battery life - among the best in its class; a 20 min quick-charge gives 4 hours. The tradeoff: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
What the Altec Lansing Lifejacket 2 does well: Tank-like build quality - reviewers have frozen it, dropped it, and buried it in sand with no issues. Watch for: Barely any bass, “pathetic sounding” said Jay’s Reviews of the line generally.
Buy the Marshall Emberton II. It is rated higher for sound quality, and the $90 saving on the Altec Lansing Lifejacket 2 is not enough to make up the difference.

Altec Lansing Lifejacket 2: $69.99 Amazon eBay
Newer model: the Altec Lansing Lifejacket 3, rated 2/5.
Pros: Tank-like build quality - reviewers have frozen it, dropped it, and buried it in sand with no issues. IP67 rated; doubles as a power bank. Universal mounting clip for a bike, kayak, or backpack. Built-in speakerphone with voice-confirmed caller ID.
Cons: Barely any bass, “pathetic sounding” said Jay’s Reviews of the line generally. Gets distorted with a lot of bass. No true wireless stereo pairing between two units, unlike the Lifejacket 3. Only available used now.
