Short answer: the B&O Beosound A1 3rd gen. It ranks #19 of 164 medium speakers by sound quality, rated 4.1/5, at $299.99. The Teufel Rockster Go 2 ranks #91, rated 3.2/5, at $129.99, $170 cheaper, a saving that is not big enough to make up the sound-quality gap.
The B&O Beosound A1 3rd gen is the better-sounding, longer-running pick. Longer battery than the 2nd gen (~24 hours at sensible volumes). It is rated for 24 hours of battery against 15 for the Teufel Rockster Go 2. At 1.2 lbs (558 g) it weighs noticeably less than the Teufel Rockster Go 2 at 1.6 lbs (735 g). It supports aptX Adaptive Bluetooth, which the Teufel Rockster Go 2 lacks. The catch: Distorts easier than the 2nd gen with deeper bass.
What the Teufel Rockster Go 2 does well: At 1.6 lbs (0.74 kg), the IP67 Rockster Go 2 is genuinely easy to carry, and its claimed 28-hour battery life, USB-C fast charging, stereo pairing, and tripod mount suit outdoor use. It plays in stereo from a single unit, unlike the B&O Beosound A1 3rd gen. The catch: There is no companion app or 3.5 mm input.
Buy the B&O Beosound A1 3rd gen. It is rated higher for sound quality, and the $170 saving on the Teufel Rockster Go 2 is not enough to make up the difference.

Teufel Rockster Go 2: $129.99 Amazon eBay
Older model: the Teufel Rockster Go (ranked lower, rated 2.6/5).
Pros: At 0.74 kg, the IP67 Rockster Go 2 is genuinely easy to carry, and its claimed 28-hour battery life, USB-C fast charging, stereo pairing, and tripod mount suit outdoor use. Independent listening found a balanced, clear midrange and tuneful bass at sensible levels.
Cons: There is no companion app or 3.5 mm input. Reviewers found it loses some definition at maximum volume, and the claimed battery figure is optimistic for loud outdoor playback.
