Marshall Willen vs JBL Go 4

Last updated: October 1, 2026

Short answer: the Willen for vocals, the JBL Go 4 for more bass than the Go 3. The Willen’s exceptionally clear vocals for a mono speaker come with shallow bass, while the Go 4 adds a little more bass than the Go 3 and fixes the strange mids peak. Even so, the Go 4 runs out of bass with electronic and bass-heavy tracks pushed past about 50% volume.
