Sound Performance

The sound performance of the JBL Flip 4 far exceeded our expectations – it delivers extremely detailed midrange and crisp highs, with deep low-end frequency bass response that is enhanced by its passive bass radiators. Music performances through the Flip 4 sounded clear, crisp and well balanced; it can also go louder than its predecessor, the JBL Flip 3 which is an added improvement. The sound quality feels rich and detailed, and you can crank up the volume on this outdoor speaker without any distortion at near maximum volume levels. Vocal performances sounded detailed with amazing soundstage and music separation which felt incredibly life-like. Listening to electronic and hip-hop music also sounded very good and enjoyable to listen to with deep and punchy beats. We were truly impressed with the sound performance of the JBL Flip 4 considering its compact and portable size. It is a really well-designed rugged Bluetooth speaker you can rely on to deliver great sound performance in an outdoor open environment.


The JBL Flip 4 is designed to be rugged with an IPX7 waterproof exterior which makes it fully waterproof – you can even submerge the Flip 4 underwater without having to worry about damaging the speaker circuitry. The speaker weighs only a mere 1.4 lbs and is designed to be highly compact and portable. It also has a nice carabiner-like string at the top of the speaker which you can use to tie the speaker to your backpack or bicycle while outdoors. The button controls are located on the top of the speaker and are intuitive and easy to use – it has a power on/off button, Bluetooth connectivity button, pause/play and volume controls. The speaker also indicates the battery life at the top of the speaker when powered on, which allows you to know exactly when to recharge. We also liked the fact that the JBL Flip 4 came with the JBL Connect+ feature which you can use to link to more than 3 speakers at a time to create a bigger and wider soundstage, which is an incredibly useful feature outdoors.

Bluetooth Connectivity

The Bluetooth connectivity on the JBL Flip 4 works like a charm and connecting it to our mobile device took a few seconds. The speaker will remember your device and automatically pair the next time you switch the speaker on – this is a really convenient feature which helps save time. The music quality streamed over the Bluetooth connection was really good and we did not experience any sudden dips or drops in sound quality. The Bluetooth range lasts a good 33 feet before the connection starts to dip off. The JBL Flip 4 also comes with a built-in noise and echo cancellation speakerphone for you to take hands free calls on the go. This is especially useful if you need to switch between listening to music and taking calls while driving or riding a bicycle.
