The Flip 4 is a portable Bluetooth speaker from JBL. Despite its compact dimensions, JBL Flip 4 is prepared with two drivers that produce mobile stereo sound. In addition, this model is characterized by a long battery life and can be coupled with other JBL spokes. For using  in the office, it also offers a hands-free mode.

JBL Flip 4 : Robust, waterproof and enduring

The 17.5 cm long and 7 cm wide Bluetooth speaker is handy and with 515 g no heavy weight. Nevertheless, the manufacturer donated him a sturdy housing with rubber coating. He is said to survive falls from mid-height and be submerged briefly under water.

Much more important, however, is the sound, for which two 40 mm drivers are responsible. Together, they make quite a decent 16 W. In addition, two lateral passive radiators have been integrated for a more intensive bass reproduction. Firmly installed is a 3000 mAh large battery, which allows use of up to 12 hours. You can fully charge it via micro USB cable in 3.5 hours.

 JBL Flip 4 :Not just double speaker pairing

Apart from the charging port, the flip 4 has an aux input for 3.5 mm jack cable. In most situations, however, the box should be wirelessly connected to a smart phone. Here can 2 Bluetooth devices at the same time be coupled and alternately serve as a sound source.

Also interesting is the JBL Connect + function, which can be used to connect up to 100 compatible speakers. This creates a synchronized system that can produce a powerful sound in the garden or at parties. The built-in microphone is not only for hands free mode but also allows control of Google Now. Simply press a button on the speaker; the phone does not have to be brought out.

Final Verdict

Although there are cheaper Bluetooth speakers than the JBL Flip 4 , but this provides a good overall package. Its durable case houses powerful stereo speakers with extra bass diaphragms. The running time and the Bluetooth functions are also positive. However, the device dispenses with a radio tuner and the ability to play MP3 files locally from a memory card. It comes in 6 different colors, always together with a micro USB charging cable.
