Short answer: the JBL Flip 7, which the notes treat as the cleaner, more neutral speaker. The Rockster Go is praised for clear mid-range, wide soundstage via Dynamore processing, IP67 waterproofing and solid battery life in a compact body with a carrying strap, but the same notes flag rolled off treble, muffled sound, strange mids and bass that is not very deep. The Flip 7 is very neutral and almost pocket size, with a 4kHz bump against it.
Buy the JBL Flip 7. It is rated higher for sound quality and still sold new, while the Teufel Rockster Go is discontinued.

The Two Speakers In Full
JBL Flip 7: $119.95 Amazon eBay
Older models: the JBL Flip 6 (ranked higher, rated 4.2/5), the JBL Flip 5 (ranked lower, rated 3.3/5) and the JBL Flip 4 (ranked lower, rated 3.3/5).
Pros: A very neutral speaker, very small, almost pocket size. Just slightly more treble than the Flip 6 which was already a great speaker. Slightly deeper bass than the Flip 6. IP68 protection, a 7-band app EQ, Auracast and a USB-C digital audio input. Measured bass extension of 59Hz (-10dB).
Cons: A little bit of a bump at 4kHz, not quite as neutral as the Flip 6. On balance it is the slightly worse of the two.
