#25 JBL Go 4: $39.95 Amazon Bhphotovideo

Pros: A little more bass than the Go 3 and they fixed the strange mids peak.

Cons: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume. Midrange can sound grainy and treble a bit sizzly; loses clarity at higher volumes.

Related speakers: JBL Go 3, JBL Go 5.

How it compares: Just above it: JBL Go 5 - $5 more, 1 more hours of battery life. Just below it: JBL Go 3 - 2 fewer hours of battery life.
