Compact Design with Premium Build
The JBL Go 4 was first introduced in March 2024 as a compact, travel-friendly Bluetooth speaker. Made with a rugged IP67-certified housing, it is both waterproof and dustproof, perfect for use outside, from pool events to trails. Even though it only has a 3-inch frame, JBL has kept a powerful design identity with its dramatic logo and convenient fabric loop that clips onto your backpack, jeans, or belt easily. The Go 4’s small size guarantees that it can fit comfortably in your hand, and as the adage goes, good things do come in small packages.
Crystal-Clear Audio with Auracast Technology
In terms of performance, the Go 4 does not skimp on audio quality. It comes equipped with JBL’s own acoustic algorithms that amplify clarity and provide rich, balanced sound at all frequencies. The small speaker delivers 5W of sound, considering its compact size, and features Auracast technology enabling users to connect two Go 4 speakers to create a stereo experience. Whether you’re watching your favorite movies on the go or listening to music during a picnic, the Go 4 provides you with immersive sound wherever you are.
Long Battery Life and Easy Connectivity
The Go 4 is connected through Bluetooth 5.3, which provides a secure and quick connection between devices with little delay. It has a battery life of up to 9 hours on a single charge, and when you use the Playtime Boost mode, the playback can be extended further. The USB-C port for charging is quite easy to recharge from, and the compact design allows you to simply throw it in your bag and not have to think about it again until you require it.
A Great Bargain This Amazon Prime Day
Listed at about $60, the JBL Go 4 was already a low-cost portable speaker. But in Amazon’s October Prime Day Sale, it’s selling for just less than $40, one of the best value-for-money audio bargains this year. It’s available in black, white, and blue, so you can choose a color to suit your style.
Final Verdict: A Must-Have for Music Fans
