Customer Review (5-Star, Natural)

As a longtime JBL fan, this tiny speaker surprised me in the best way. It delivers clear mids and a surprisingly punchy bass for its size, filling a small room or patio without distortion. The build feels sturdy, and the strap makes it easy to carry anywhere. I’ve knocked it around at the beach and it keeps playing, while the battery life easily handles a full day of listening. Pairing with a second Go 4 for stereo is effortless, and the Auracast option is a great plus. I also appreciate the eco-friendly design and recyclable packaging. For its compact footprint, this Go 4 is hard to beat.
