Our Testing Experience
First Impressions
When I first took the JBL Go 4 out of the box, I was surprised at how small and light it was. It easily fit in the palm of my hand, making it super easy to carry around. I decided to test it right away by playing some of my favorite songs. Honestly, I didn’t expect much from such a tiny speaker, but the sound was really clear and the bass was punchy. It was impressive how much volume and quality JBL packed into this little device.
Daily Use
Over the next few days, I brought the JBL Go 4 everywhere – to the kitchen while cooking, outside to the park, and even to the bathroom during my shower. The waterproof feature gave me peace of mind, and I wasn’t afraid to use it near water or in dusty places. The battery lasted well throughout the day, and when it started running low, I used the Playtime Boost feature to get a couple more hours without needing to plug it in immediately. It was great to have music on the go without worrying about recharging all the time.
Key Features in Action
The waterproof and dustproof rating really stood out for me. During a picnic by the lake, the speaker got a little wet from splashes and some sand dust, but it kept working perfectly. The JBL Pro Sound with punchy bass made outdoor listening fun, even when there was background noise. The compact size made it easy to stash in my bag or even pocket, so I never felt weighed down. Plus, the simple Bluetooth connection was quick and hassle-free every time.
Long-Term Performance
After using the JBL Go 4 for a few weeks, I noticed it still delivered consistent sound quality without any drop in battery life. The build feels sturdy and durable, which makes me confident it will last a long time, especially for outdoor use. I also appreciated that it’s made partly from recycled materials – it feels good to use a product that’s a bit kinder to the environment. Overall, it’s become my go-to speaker for everyday music and small gatherings.
