Short answer: the Soundcore 2. It ranks #92 of 150 medium speakers by sound quality, rated 3.0/5, at $29.99; the Altec Lansing Lifejacket 2 ranks #149, rated 2.0/5, and costs $69.99, so there is not much of a tradeoff to weigh.
The case for the Soundcore 2: Soundcore 2 uses 2x 38mm fullrange. Watch for: Its 70Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size.
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. The catch: Barely any bass, “pathetic sounding” said Jay’s Reviews of the line generally.
Buy the Soundcore 2. It is rated higher for sound quality than the Altec Lansing Lifejacket 2 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
