Short answer: the Teufel Boomster Go if sound quality comes first; the JBL Go 5 for price and water resistance. The Boomster Go ranks #7 of 54 with pretty deep, balanced bass, though distortion becomes audible above roughly 75% volume and it turns unclear and tinny at max volume. The Go 5 adds a 7-band app EQ and AirTouch stereo pairing, but our notes call it still lacking bass and not very clear overall.
JBL Go 5 bumps IP68 protection up from the Go 4’s IP67 and adds AirTouch tap-to-pair stereo linking with a 7-band app EQ, but our notes describe it as still lacking bass and not very clear overall, falling well short of rivals like the Tribit Stormbox Micro 2.
Teufel Boomster Go delivers pretty deep bass and a quite balanced overall sound for its size, though distortion becomes audible above roughly 75% volume and gets unclear and tinny at max volume up close.
Buy the Teufel Boomster Go if sound quality is the priority and its higher price is acceptable. Buy the JBL Go 5 if you want the lower price, better water resistance and easy stereo pairing with a second unit.

The Two Speakers In Full
JBL Go 5: $39.95 Amazon eBay
Older models: the JBL Go 4 (ranked lower, rated 3.2/5) and the JBL Go 3 (ranked lower, rated 3.2/5).
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.
