Bose SoundLink Color II vs Teufel Rockster Go

Last updated: August 19, 2026

Short answer: the Bose SoundLink Color II. It ranks #98 of 136 medium speakers by sound quality; the Teufel Rockster Go ranks #103.

On the Bose SoundLink Color II side: Soft-touch rubber coating is comfortable to hold and tough enough for bumps and scrapes. The catch: Boosted bass on Color II. Not as deep of bass as other models. Lacking midrange detail.

The case for the Teufel Rockster Go: Clear mid-range with bright treble, wide soundstage via Dynamore processing, IP67 waterproof and durable, solid battery life, compact design with carrying strap. Set against that: Rolled off treble, muffled sound, mids sound strange. Bass not very deep.

Buy the Bose SoundLink Color 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 water resistance matters to you, the Teufel Rockster Go at IPX7 (brief submersion) holds up far better than the Bose SoundLink Color II at IPX4 (splashing).
