Short answer: the Ultimate Ears Wonderboom 4. It ranks #84 of 136 medium speakers by sound quality; the Teufel Rockster Go ranks #103.
What the Teufel Rockster Go gets right: Clear mid-range with bright treble, wide soundstage via Dynamore processing, IP67 waterproof and durable, solid battery life, compact design with carrying strap. The tradeoff: Rolled off treble, muffled sound, mids sound strange.
What the Ultimate Ears Wonderboom 4 offers: Small size. Set against that: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
One note: the Teufel Rockster Go is discontinued, but it still ranks #103 of 136 medium speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the Teufel Rockster Go if the price matters more than sound quality. Buy the Ultimate Ears Wonderboom 4 if sound quality matters more than the price.
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.
