JBL Go4

Reviewer verdict

Across 29 YouTube reviews, the JBL Go4 earns a Summa score of 4/5, ranking #37 among Bluetooth Speakers. Reviewers most often praise its design, connectivity, features, while the most common criticisms concern sound quality, battery life.

Praised for its extreme portability, the JBL Go 4 is incredibly compact and lightweight, making it easy to carry anywhere. Reviewers consistently highlight its surprisingly powerful and clear sound, with punchy bass that defies its small dimensions. Its rugged construction, featuring an IP67 waterproof and dustproof rating and durable recycled materials, makes it a reliable companion for outdoor adventures. Modern features add significant value, including stable Bluetooth 5.3 connectivity, the ability to pair multiple speakers via AuraCast for stereo or group playback, and robust support from the JBL Portable app, which offers a customizable 5-band equalizer.

The most significant drawback is its battery performance; the 7-hour advertised playtime drops to just 3-4 hours at high volumes, and a full recharge takes a slow three hours. While the 'Playtime Boost' feature extends battery life, it does so by drastically cutting bass and degrading overall sound quality. Many reviewers also noted the absence of a built-in microphone, which means it cannot be used for hands-free calls or interacting with voice assistants. Other limitations common to speakers this size include a lack of deep sub-bass and the removal of an auxiliary input.
