Short answer: the Marshall Emberton II. It ranks #100 of 136 medium speakers by sound quality; the Teufel Rockster Go ranks #103.
On the Marshall Emberton II side: 30 hour battery life - among the best in its class; a 20 min quick-charge gives 4 hours. Set against that: Strange unnatural echo-like sound coloration, bass not as deep as competitors.
What the Teufel Rockster Go offers: Clear mid-range with bright treble, wide soundstage via Dynamore processing, IP67 waterproof and durable, solid battery life, compact design with carrying strap. Watch for: Rolled off treble, muffled sound, mids sound strange. Bass not very deep.
Buy the Marshall Emberton II if sound quality matters more than the price. Buy the Teufel Rockster Go if the price matters more than sound quality.
If sound quality matters at all to you, skip the Teufel Rockster Go. It ranks near the bottom of the 136 medium speakers, so look higher up the list instead.
If battery life is a priority, the Marshall Emberton II is rated for 30 hours versus 12 hours for the Teufel Rockster Go.
