Short answer: the Teufel Rockster Go for sound, the B&O Beosound Explore for battery life, though neither ranks well in its class. Both are IP67 and built for outdoor use, but the Go’s Dynamore processing gives it a wide soundstage, even though our notes call its treble rolled off and its bass not very deep. The Explore runs a real-world 20-24 hours but has a huge lack of bass extension and overly hot ringing treble. Both are rated below 3.0/5 among the 164 medium speakers, so if sound quality matters, consider the Earfun Uboom L instead, ranked #2 at $49.79.
Buy the B&O Beosound Explore, since the Teufel Rockster Go is discontinued and only worth hunting down used.
There is a real battery-life gap here: the B&O Beosound Explore is rated for 27 hours, the Teufel Rockster Go only 12 hours.
