Who Should Buy This
The JBL Go 4 is perfect for anyone who wants a small, easy-to-carry speaker with great sound. It is ideal for people who enjoy outdoor activities like hiking, beach trips, or pool parties because it is waterproof and dustproof. If you want good bass and clear sound without spending a lot, this speaker is a great choice. Its 7-hour battery life means you can listen to music for a long time without charging. Plus, it is made partly with recycled materials, so it’s a good pick for those who care about the environment.

Our Testing Experience
First Impressions
When I first unboxed the JBL Go 4, I was genuinely surprised by how small and lightweight it felt. It fits comfortably in one hand, which made me wonder if it could really deliver the big sound JBL promises. In this JBL Go 4 Review, I tested it in my backyard by connecting it to my phone via Bluetooth. The setup was fast and completely hassle-free. As soon as I hit play, I was impressed by how clear and punchy the sound was coming from such a tiny speaker—it truly doesn’t sound like a speaker this compact.
Daily Use
Over the next few days, I carried the JBL Go 4 with me everywhere—on my morning walks, to the kitchen while cooking, and even to a small get-together with friends. It was ultra-portable, slipping easily into my bag or pocket. The waterproof and dustproof features gave me peace of mind, especially when I took it near the pool and on a dusty trail hike. It survived splashes and dirt without any issues. The battery life was impressive too; I only had to charge it every few days, even with regular use.
Key Features in Action
The punchy bass really stood out, especially when playing upbeat music. It made the small speaker feel much bigger. The JBL Pro Sound quality was clear, with no distortion even at higher volumes. I loved the Playtime Boost feature—it gave me extra listening time when I was out longer than expected, which was super convenient. The waterproof and dustproof rating proved useful when I accidentally dropped the speaker into a shallow puddle. It worked perfectly afterward, which was a big relief.
Long-Term Performance
After using the JBL Go 4 for several weeks, I can say it’s been a reliable little companion. The sound quality stayed consistent, and the battery life did not degrade noticeably. It’s held up well through outdoor adventures and everyday use, showing no signs of wear or damage. I appreciate that it’s made in part with recycled materials, which makes me feel better about choosing it. Overall, this speaker has exceeded my expectations for such a compact device.

In my opinion, this JBL Go 4 (Black) stands out because it combines ultra-portability, strong JBL Pro Sound with punchy bass, and a solid 7-hour battery life with a rugged IP67 waterproof and dustproof design—all while being partly made from recycled materials. Compared to the JBL Clip 5, it offers a more compact form factor, making it ideal if you prioritize size and portability over extra battery life and the carabiner feature. If you prefer a simple, stylish, and environmentally mindful speaker that doesn’t require a clip, this is the better choice.
