Short answer: the Teufel Boomster Go. It ranks #7 of 47 small speakers by sound quality; the JBL Go 5 ranks #24.
The case for the JBL Go 5: IP68 rating, up from the Go 4’s IP67. The catch: Still overpriced for what it delivers, not very different from the Go 4 besides the lights.
On the Teufel Boomster Go side: Pretty deep bass and quite balanced overall for the size. Watch for: Distortion becomes audible above roughly 75% volume; at max volume up close it gets unclear and tinny.
One note: the Teufel Boomster Go is discontinued, but it still ranks #7 of 47 small speakers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the JBL Go 5 if the price matters more than sound quality. Buy the Teufel Boomster Go if sound quality matters more than the price.

The Two Speakers In Full
JBL Go 5: $44.95 Amazon
Pros: IP68 rating, up from the Go 4’s IP67. AirTouch tap-to-pair stereo linking. 7-band custom app EQ, up from the Go 4’s 5-band. USB-C wired audio input.
Cons: Still overpriced for what it delivers, not very different from the Go 4 besides the lights. Still lacking bass and not very clear overall. Mono downmixing produces an audible growling artifact, the same issue noted on the JBL Charge 6. Falls well short of similarly priced rivals like the Tribit Stormbox Micro 2. Weak off-axis dispersion and an uneven, upper-mid-heavy tonal balance. Doesn’t get meaningfully louder at max volume, just harsher.
