Short answer: the Soundcore 2. It ranks #105 of 179 medium speakers by sound quality, rated 3.0/5, at $29.99; the DOSS E-Go II ranks #148, rated 2.5/5, and costs $39.90, so there is little reason to consider the other one.
The Soundcore 2 is the better-sounding, longer-running pick. A cheap, light waterproof stereo speaker with a long rated battery, an aux input and pairing with a second unit. It is rated for 24 hours of battery against 12 for the DOSS E-Go II. At 0.7 lbs (318 g) it weighs noticeably less than the DOSS E-Go II at 0.9 lbs (399 g). Watch for: Bass is specified only down to 70Hz, so the low end is limited.
The case for the DOSS E-Go II: A water bottle sized stereo speaker with water resistance and quick pairing, light enough for a cup holder or bag. The catch: Horribly bad unless turned up, still not great.
Buy the Soundcore 2. It is rated higher for sound quality than the DOSS E-Go II and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
