Features of JBL Flip 4 and UE Boom 2

Design

Featuring a cylindrical shape, both of them are designed to protect the inside speakers while still being visually appealing.

While UE Boom 2 comes in two colors and can have infinite combinations by request and for extra costs, the JBL Flip 4 comes as monochromatic, featuring only six single colors to choose from. If chromatics is very important to you, you might fall in love with these devices. 

The JBL Flip 4 has an optimized design, featuring the well-known cylindrical shape that JBL uses for most of its portable speakers including JBL Pulse 2 and Charge 3It is compact and lightweight, and that makes it perfect for carrying it on a backpack.

The UE Boom 2 is easy to carry too and well-engineered, but it is much more about the surface’s smoothness and high-quality feeling.

Overall, after reviewing both speakers, we consider that there is a slight difference between JBL Flip 4 and UE Boom 2.

JBL Flip 4 and UE Boom 2 Sound Quality

If the speakers feature many similarities at design comparison, we will now take a more in-depth insight into the sound qualities. 

Given their sizes, it is understandable that the bass won’t be their top feature, yet these speakers don’t disappoint. The bass will never get as low as a complex multi-piece sound system would, and it is perfectly defined for both of them.

While JBL Flip 4  does not distort at all on low frequencies, even at the maximum volume, it can reach more resonant frequencies like 70 Hz compared with UE Boom 2 that can reach only 90 Hz.

UE Boom 2 does not disappoint either, but when frequently used on higher volumes, the battery won’t keep up, so you will need to get prepared for plugging the charge.

Our experts noticed that both speakers are somehow preset to minimize the middle frequencies a little bit. 

If you are into music genres where the vocals matter the most, or some mid-ranged instruments as in jazz [1], classical, or anything acoustic, you will get the feeling of something unfitting. However, this should not bother you too much. 

Regarding high frequencies alone, UE Boom 2 tends to sound clearer yet a little too highlighted. On the other hand, JBL Flip 4 keeps the sound accuracy although it does not reach that high peaks as UE Boom 2.

Our experts concluded that while both of these speakers are generally well equalized, the JBL Flip 4 sounds a little bit warmer than the UE Boom 2.

Waterproofing

The JBL Flip 4 vs UE Boom 2 comparison analysis also checks if these speakers are waterproof and what additional features they have.

JBL Flip 4 is waterproof just like JBL Flip 5, including a waterproof speaker. Our experts tested the inbuilt IPX7 waterproofing system, and they noticed that JBL could indeed survive underwater. 

UE Boom 2 is waterproof as well. Both speakers are using an inbuilt IPX7 waterproofing system. This feature enables the user to listen to music even in heavy rain conditions.

Additionally, the JBL Flip 4 has some really useful and quite proactive features such as shock proofing, dust proofing, and droplets proofing — this is quite a resistant gadget.

Voice Assistants

You can control the speakers by voice command because they feature voice recognition and are working well with Google Assistant and Siri. So UE Boom 2 vs JBL Flip 4 has no winner or loser in this case.

Wireless Connectivity

JBL allows users to connect two JBL Flip 4 speakers in party mode via the JBL Connect app, summing the left and right channels in both speakers or splitting them, as per the user’s choice.

However, our experts noticed that while using the JBL app feature, you just cannot connect Flip 4 to other JBL speakers, not even to JBL Flip 3.

On the UE Boom 2 side, only party mode is available. However, you can connect it to other Bluetooth speakers particularly UE speakers such as Original Boom, Boom 3, and Megaboom.

JBL Flip 4 lacks the NFC option, but it has a stereo connection via the JBL Connect app, while UE Boom 2 does not, but has the NFC option.

Regarding the number of Bluetooth connections that each speaker supports, our experts agreed: JBL Flip 4 can get only 3, while UE Boom 2 can support up to 8 connections.

Obviously, the winner of UE Boom 2 vs JBL Flip 4 competition is the UE Boom speaker. 

Battery Life of the JBL Flip 4 and UE Boom 2

If there is an inconvenience about UE Boom 2 power supply, this is the fact that on heavy usages such as high volumes and too much bass play, the battery life shortens faster than it would do on everyday use. This normally happens even in other Bluetooth speakers like JBL’s Xtreme or Bose Soundlink 3

Talking of normal usage, the UE Boom 2 speaker can support up to 15 hours of continuous functioning and the charge time is about 3.4 hours. Not bad!

JBL Flip 4 can play up to 12 hours and the charge time is about 3.5 hours. It is better than the battery life of Harman Kardon Onyx 2 and Onyx 3 that can only last five hoursNot bad either, but our experts agreed on the winner of UE Boom 2 vs JBL Flip 4 discussion. 

JBL Flip 4 and UE Boom 2 Price

Another attractive JBL Flip 4 vs UE Boom 2 topic is related to their prices.

These Bluetooth speakers are quite similar, hence the fact that back in 2017, when these gadgets were launched, their prices were similar. However, as time had passed, the prices varied in some unexpected way.

As our experts pointed out, despite both speakers being built with the same technology, the UE Boom 2 is slightly more expensive than JBL Flip 4 or even Charge 3.

Occasionally, depending on the seller and the stock availability, you can find great deals on both of these speakers.

What about the warranty? JBL Flip 4 comes with a 1-year warranty, while UE Boom 2 comes under a 2-years warranty.
