Short answer: the Teufel Rockster Go. It ranks #103 of 136 medium speakers by sound quality; the Sony SRS-XB30 ranks #104.
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. Set against that: Rolled off treble, muffled sound, mids sound strange. Bass not very deep.
The case for the Sony SRS-XB30: IPX5 rated. Doubles as a power bank for charging your phone. Long claimed battery life (up to 24 hours at moderate volume). The catch: Muffled sound, worse than a XB20.
Buy the Teufel Rockster Go if sound quality matters more than the price. Buy the Sony SRS-XB30 if the price matters more than sound quality.
If sound quality matters at all to you, skip both of these and look higher up the 136 medium speakers instead.
If battery life is a priority, the Sony SRS-XB30 is rated for 24 hours versus 12 hours for the Teufel Rockster Go.
