Sony SRS-XB20 vs Teufel Rockster Go

Last updated: August 20, 2026

Short answer: the Sony SRS-XB20. It ranks #94 of 136 medium speakers by sound quality; the Teufel Rockster Go ranks #103.

The case for the Sony SRS-XB20: IPX5 rated pill shape slides easily into a bag. The catch: Sounds thin at higher volumes.

On the Teufel Rockster Go side: 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.

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 Sony SRS-XB20 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.
