Short answer: the Marshall Emberton II, narrowly, though neither ranks well in its class. The Rockster Go is IP67 with a carrying strap and a wide soundstage via Dynamore processing, and it ranks #126 of 164 medium speakers against the Emberton II’s #123 of 164. But its treble is rolled off, its mids sound strange and its bass is not very deep, while the Emberton II manages 30 hours with a 20 minute quick charge. Both are rated below 3.0/5 among the 164 medium speakers, and the Earfun Uboom L, ranked #2 at $49.79, is a better place to start if sound quality matters.
Buy the Marshall Emberton II. It is rated higher for sound quality and still sold new, while the Teufel Rockster Go is discontinued.

Marshall Emberton II: $144.99 Amazon eBay
Newer model: the Marshall Emberton III, ranked higher, rated 2.7/5.
Pros: 30 hour battery life: among the best in its class; a 20 min quick-charge gives 4 hours. IP67 rated, durable rubbery build using 50% recycled plastic. Measured bass extension of 62Hz (-10dB).
Cons: Strange unnatural echo-like sound coloration, bass not as deep as competitors. Not technically a 360 speaker, only front and rear. Not very loud.
