Thanks to the compact size, you can easily take a mini JBL speaker with you on the go. This way, you can effortlessly put the speaker in your bag or hold it in your hand. Due to the small size, the volume isn't very high. This means you only listen to the music yourself when you're on your bike, for example. You can listen to your music for 7 hours with the JBL Go 4, so you can easily take it with you the entire day.
