After analyzing the JBL Flip 4 Waterproof Portable Bluetooth Speaker, we have been left with a good taste in our mouths. The market for portable Bluetooth speakers has grown substantially in recent years. Many brands offer good options and JBL is a good example. The American brand has long stood out for the quality of its audio devices, and this year it has focused much of its efforts on the production of various wireless speaker options. This JBL Flip 4 speaker review will help you to know about its features, price & experts’ opinions.

We recently published JBL Xtreme 2 speaker review, a very powerful portable speaker with excellent performance. Now, we will focus on the latest release in one of its cheaper series: the JBL Flip 4 BT Speaker.

With a price of around 90 dollars, it is a very affordable speaker. It is cheaper than the UE Boom 2, although they share very similar characteristics. With IPX7 water protection and a very sturdy cylindrical construction, this little loudspeaker has a very justified value.

Design

JBL Flip 4 Speaker
  • Size: 68 x 175mm
  • Weight: 515 grams.
  • Power: 2 x 8W
  • Battery: 14 hours

The design of the JBL Flip 4 portable Bluetooth speaker is very similar to that of its predecessor, the Flip 3. It still maintains a cylindrical shape albeit slightly larger in size, with two external passive radiators positioned at each end of the speaker. On the other hand, it does present a very important difference: it has improved protection against water.

It provides IPX7 resistance to water and dust, which means that it can be submerged up to one meter deep for a time of approximately thirty minutes. Its weight, size, and protection make it one of the best options, among the portable speakers on the market, to take on any trip or excursion.

In the front area of ​​this portable speaker, we can access the buttons for the Bluetooth connection, power, volume, and hands-free function. These are made of plastic and come in a fairly large design, allowing for easy access.

On the back, we will find a battery indicator that works with five small LED lights, which indicate the status of the battery. The JBL Flip 4 portable speaker provides another button to sync multiple JBL Bluetooth speakers via JBL Connect +. However, more devices need to have this new technology to take advantage of it. It has been announced that in addition to the Flip 4, the JBL Bluetooth speaker models will feature an update that will allow them to join via JBL Connect Plus.

Hidden under a protective rubber cover are a micro USB port and a 3.5mm Aux input, which we can use when we do not have a Bluetooth mobile device at hand. The Flip 4 also has a cord attached to the body of the speaker, a very useful addition for travel, as it will allow us to hang it anywhere. We can also use it while taking a shower.

Sound

The JBL Flip 4 wireless speaker has many virtues when it comes to sound. It packs lot of power for a portable speaker of its size, and its use, both indoors and outdoors, yields good results. The audio lacks a bit of refinement and subtlety, but this is to be expected in a Bluetooth speaker. It sounds great when playing electronic or hip-hop music, as these genres take advantage of the great low-frequency response that the device provides. It has a sensitivity (SPL) of 90 decibels, although it is recommended not to exceed 85 to avoid possible distortions.

This portable Bluetooth speaker has a sound very similar to the JBL Flip 3, which is not a negative since the previous version was of good quality. One of the small differences can be noticed in the high tones. The Flip 3 exhibited a small distortion when reaching maximum volume, a flaw that has been eliminated in the new model. In the middle tones, we find that the vowels sound very clear and strong. Companion instruments can lose a bit of power in comparison, but not so much that this is a problem.

Another small change with respect to the JBL Flip 3 is found in the low tones. The new speaker features a more powerful bass than its predecessor. Tests show that it also outperforms the UE Wonderboom in this section, making it a better option. The JBL Flip 4 mobile speaker also comes with dual 40mm drivers, which give us great sound and allow a response of the low frequencies that avoid drowning out the high tones.

On the other hand, the dual 8W passive radiators can be seen working when we play songs with a strong bass presence. The radiators are linked, although they are positioned at both ends of the speaker. This avoids the distortion that can occur when a single passive radiator has worked hard.

Perhaps the most striking aspect of this portable speaker is its ability to sound remarkably outdoors, even when there is an excess of ambient noise. It may not be the best indoor speaker, as it doesn’t sound as slick as the Bose SoundLink Mini II, but it comes in a much more compact size and has a very robust build.

A direct competitor would be the UE Boom 2, and against it, the sound of the JBL Flip 4 stands out. However, unlike the UE Boom 2, it doesn’t have a true 360-degree sound. Its high tones come from both sides of the JBL logo, located on the front, and not from the ends of the speaker. So the sound is much more directional.

Connectivity

  • The JBL Flip 4 has an integrated microphone that we can use as a hands-free for our phone.
  • The microphone also has the ability to activate virtual assistants like Siri or Google Now.The range of the Bluetooth speaker impresses. Even 12 meters away, and with walls in between, it continues to work without problems.
  • You can use JBL Connect + technology to pair the Flip 4 with other JBL portable speakers , both for increased sonic capacity and to create a stereo system. Below I have attached a video. Learn how to connect multiple JBL speakers together.

  • JBL also integrated a 3.5 auxiliary connection and a micro-USB charging port into the Flip 4 portable speaker. Both are very useful as extras to bluetooth 4.2 connectivity.
  • The speaker has the ability to connect to two wireless sources at any time.

Battery

JBL ensures that the battery, with a capacity of 3000 mAh, can reach 12 hours of continuous playback. When running a test using 50% of the volume capacity, we got up to 14 hours and there was still 50% battery left. When testing the portable speaker using full power, however, we found that it actually lasts for about 4 hours, as the battery drain is considerably higher. This capacity doubles that of the UE Boom 2, its closest competitor.

Conclusion

It is one of the best wireless speakers at a quality price. With the improvements made by JBL to Flip 4, the problem of choosing between price and quality is behind us. The sound from this portable speaker impresses with great bass and crisp vocals. In addition, the total protection against water or dust makes it an ideal option to take anywhere.

The UE Wonderboom and the Boom 3 are other good options. The Wonderboom can float and the Boom 3 offers 360-degree sound. However, the JBL Flip 4 boasts a better battery and superior sound than both UE devices. If you are looking for an option with a bit more size and power, we recommend you review the JBL Charge 4 on our sound culture page.

If you already own a JBL Flip 3, you will have to decide if the capacity of this waterproof portable speaker is enough to buy it. If you are instead looking to buy your first Bluetooth speaker, resistant and at an affordable price, you may not find a better option.
