JBL and Ultimate Ears are quite popular and have been dominating the market. This may be because they produce decent, long-lasting speakers for music lovers. In this article, we compare JBL Flip 3 and UE BOOM 2. We selected these two because their features are not too different despite their price discrepancy. (And we also want to see why that price difference is so!) Read our bite-sized discussions about their features below, and we hope these help you decide which one to buy.

JBL flip 3 vs UE Boom 2

Features and Specs


JBL Flip 3

The driver is an individual transducer. Its function is generating sound waves from electrical energy. In other words, this is the part of your speaker that produces sound. In general, the bigger the driver, the more power your speaker and the better its bass. Also, more drivers may mean better sound. JBL Flip 3 and UE BOOM 2 have two drivers each. That of JBL Flip 3 measures 40 mm, and that of UE BOOM 2 measures 45 mm.

Form Factor

We are not counting form factor in deciding who the winner is because we all have different preferences, but to give you an idea of how big these speakers are, these are their measurements:

JUE Boom 2
JBL Flip 3 UE BOOM 2
Height 64 mm 67 mm
Width 169 mm 180 mm
Weight 450 g 548 g
Body Volume 692.22 cm^3 808.02 cm^3

Stereo Speakers

Stereo is great because it means that the device produces sound from independent left and right channels, so the sound is rich and the overall experience is good. You can more easily immerse yourself in whatever you are listening to. Of the two, only JBL Flip 3 has this.

Active Speaker

This feature means that the device has an amplifier integrated in it. The amplifier boosts a signal without tweaking anything else in the system. You can connect any sound source to the device. Both JBL Flip 3 and UE BOOM 2 are active speakers.
On-device Control Panel

We think this is a basic feature, but it gets overlooked surprisingly often. Luckily, both JBL Flip 3 and UE BOOM 2 have control panels on the speakers themselves. You do not need to grab the remote or connect the speakers to any other gadget to change anything. UE BOOM 2 can even be tapped simply to change songs, for example.

Socket for Audio Jack

Both JBL Flip 3 and UE BOOM 2 have sockets for 3.5 mm audio jacks. That means they can be used with most headphones.

USB Ports

JBL Flip 3 and UE BOOM 2 have one USB port each. This is typical among speakers in this price range.

Minimum Frequency

The minimum frequency is the lowest at which your speaker can produce sound. Basically, the lower this figure, the stronger and the better your bass. JBL Flip 3 has a minimum frequency of 85 Hz, and UE BOOM 2 has a minimum frequency of 90 Hz.

Maximum Frequency

The higher the maximum frequency, the cleaner your treble. Both JBL Flip 3 and UE BOOM 2 have a maximum frequency of 20000 Hz.


JBL Flip 3 and UE BOOM 2 vary here but only negligibly. The former uses Bluetooth ver. 4.1, and the latter uses Bluetooth ver. 4. UE BOOM 2 allows you to do Bluetooth pairing via NFC. This is a great feature that makes things a lot faster.


Both have battery level indicators and use rechargeable batteries so they can be used wirelessly. The charge times differ by only a very small margin. The JBL Flip 3 and the UE BOOM 2 take 3.5 and 3.4 hours to charge, respectively.

Multipoint Count

In a nutshell, the higher the multipoint count, the more Bluetooth devices you can connect and the more easily and quickly you can switch among these devices. The multipoint count of JBL Flip 3 is 3, and that of UE BOOM 2 is 8.

Noise-canceling Mic

A noise-canceling mic filters out background noise. If you frequently listen to music while in loud places, you may need this. This feature also results in reduced battery consumption because you do not need to crank up the volume too much to hear your music in a loud environment.

Weather Sealing

The meaning of “weather sealing” can vary, so we need to specify what kind of sealings JBL Flip 3 and UE BOOM 2 have. The former is labeled “splashproof.” However, JBL warns that you are not to submerge the speaker. Meanwhile, the latter is IPX-7 rated. That means it is waterproof. It can be submerged in 1 m water depth for up to 30 minutes without getting damaged. It is also shockproof.

Smartphone Control

Use your smartphone as remote control for the speaker. JBL Flip 3 does not have this feature, and UE BOOM 2 does.

AUX Input

Both speakers have this feature. You can connect other audio sources to them through an audio connection.


Which One to Buy?

In summary, UE BOOM 2 is better than JBL Flip 3 ibecause it has a slightly larger driver, allows Bluetooth pairing via NFC, remote control via smartphone, better weather sealing, and higher multipoint count.

Meanwhile, JBL Flip 3 has stereo, lower low-frequency response, slightly newer Bluetooth, and a noise-canceling mic, which we think is important than some of UE BOOM 2’s hits.
