Short answer: the Xiaomi Sound Outdoor. It ranks #44 of 150 medium speakers by sound quality, rated 3.7/5, at $54.99; the Altec Lansing Lifejacket 2 ranks #149, rated 2.0/5, and costs $69.99, so there is little reason to consider the other one.
The case for the Xiaomi Sound Outdoor: Xiaomi Sound Outdoor uses 20W woofer, 10W tweeter + 2x passive radiators. The tradeoff: Its 60Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size.
Why pick the Altec Lansing Lifejacket 2: Tank-like build quality: reviewers have frozen it, dropped it, and buried it in sand with no issues. The tradeoff: Barely any bass, “pathetic sounding” said Jay’s Reviews of the line generally.
Buy the Xiaomi Sound Outdoor. It is rated higher for sound quality than the Altec Lansing Lifejacket 2 and costs less, so only choose the other one for a particular feature it does better.
There is a real battery-life gap here: the Altec Lansing Lifejacket 2 is rated for 30 hours, the Xiaomi Sound Outdoor only 12 hours.

The Two Speakers In Full
Xiaomi Sound Outdoor: $54.99 Amazon eBay
Pros: Xiaomi Sound Outdoor uses 20W woofer, 10W tweeter + 2x passive radiators. Its 597 g, claimed 12 hours (Manufacturer specified) battery life, IP67 protection and mono playback make it a practical option for its intended room or portable use. A decent sounding speaker for its size.
Cons: Its 60Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size. There is no companion app. No EQ adjustment. Boosted bass that gets somewhat uncontrolled at high levels.

Altec Lansing Lifejacket 2: $69.99 Amazon eBay
Newer model: the Altec Lansing Lifejacket 3, ranked higher, 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.
