The Two Speakers In Full
JBL Go 5: $39.95 Amazon eBay
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.
