Short answer: the Soundcore 2. It ranks #105 of 182 medium speakers by sound quality, rated 3.0/5, at $29.99; the Altec Lansing Lifejacket 2 ranks #180, rated 2.0/5, and costs $62.99, so there is not much of a tradeoff to weigh.
The Soundcore 2 is the better-sounding, lighter choice. A cheap, light waterproof stereo speaker with a long rated battery, an aux input and pairing with a second unit. At 0.7 lbs (318 g) it weighs much less than the Altec Lansing Lifejacket 2 at 2.7 lbs (1.22 kg). It plays in stereo from a single unit, unlike the Altec Lansing Lifejacket 2. Watch for: Bass is specified only down to 70Hz, so the low end is limited.
What the Altec Lansing Lifejacket 2 does well: A nearly indestructible waterproof speaker that doubles as a power bank, with a clip for bikes, kayaks or backpacks. 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.
