- The JBL Go 4 is a small, ultra-portable Bluetooth speaker that is a successor to the popular JBL Go 3. It maintains the Go series’ reputation for being durable, compact, and affordable, while introducing some notable upgrades.

- JBL Portable App Support: This is a major improvement over the Go 3. The app allows you to customize the sound with a 5-band graphic equalizer (EQ) or choose from preset EQ options. This gives you much more control over the sound profile, which was a common criticism of the previous model.
- Improved Durability: While both the Go 3 and Go 4 have an IP67 rating (waterproof and dustproof), the Go 4 features additional rubberized silicone around the edges for extra protection against drops and wear.
- Auracast Compatibility: The Go 4 supports Auracast, which allows you to connect multiple Auracast-enabled JBL speakers (including other Go 4s, Clip 5s, or Xtreme 4s) for a multi-speaker “party mode” or to create a stereo pair with two Go 4 speakers.
- Longer Battery Life: The Go 4 offers up to 7 hours of playtime on a single charge, which is an improvement over the 5 hours of the Go 3. There’s also a “Playtime Boost” feature that can add up to 2 hours of battery life by optimizing performance.
- Updated Bluetooth: It comes with Bluetooth 5.3, offering a more stable and efficient connection than the Go 3’s Bluetooth 5.1.
- Eco-Friendly Design: The Go 4 is made in part with post-consumer recycled plastic and fabric, and is packaged in FSC-certified paper printed with soy ink.

Sound Quality
Despite its small size, the JBL Go 4 is praised for its “JBL Pro Sound” with “punchy bass.” While it won’t deliver a window-rattling experience, for its size and price, reviewers note it provides a cohesive and engaging sound. The ability to use the customizable EQ in the app is a game-changer, allowing users to tweak the sound to their liking and even squeeze out a bit more bass.

The JBL Go 4 is widely considered a worthy successor to the Go 3. It retains the rugged, ultra-portable design while adding key features like app support with a customizable EQ, longer battery life, and Auracast connectivity. If you’re looking for an affordable, durable, and highly portable speaker with surprisingly good sound for its size, the JBL Go 4 is an excellent option.
