Review Ultimate Ears Boom 3

The UE BOOM 3 is a wonderful speaker and has made a lot of incremental improvements:

Sophisticated design

Looking at UE BOOM, one can immediately recognize the typical design of UE products, but there are a few notable points here. It’s difficult to notice because, although it looks familiar, UE BOOM 3 receives very small but subtle tweaks. Gone are the designs of a plastic bumper in the middle of the speaker with a plus and minus button. Instead, there is a thinner plastic strip running along the speaker body.

In the new version, the company also removed the rubber layer in the middle of the speaker body, so we also have a slightly more seamless design. On the top edge, we have 3 buttons instead of 2 like before, including 1 Bluetooth toggle button, power button, and 1 dedicated button to stop/play music.

Bright and clean Sound Quality 

This speaker is small, but its volume is very loud. Perhaps due to focusing a lot on this high volume, the sound of UE BOOM 3 does not really have depth. With Ultimate Ears’ unique sound processing feature, Ultimate Ears BOOM 3 makes a powerful impression with a frequency range of 90Hz – 20kHz, meeting most music genres, creating clear, balanced and neutral sound. true at any volume level.

In particular, the outstanding sound frequency that this speaker brings is the strong bass frequency. The cylindrical design helps surround sound easily spread 360 degrees in all directions, bringing vivid music to every part of your space.

The high sound range is not special, stopping at an easy-to-listen level at volume levels below 80%. Over 80% will have the phenomenon of cymbal and jingle sounds being harsh and too loud.

The battery

UE claims that the battery life on the UE BOOM 3 is 15 hours of continuous playback. At the bottom, we have a new feature: a connector to help the speaker charge via the dock. Users will buy a separate charging dock for $40, and can plug it in so the speaker becomes a permanent speaker without ever worrying about running out of battery.

Wireless Connectivity

Although the latest bluetooth standard has not been announced, it allows connection at a distance of up to 30m, 3 times greater than other speaker models on the market.

Advanced Features

Next, the UE BOOM 3 comes with a supporting app. The One-touch Playlist feature integrated into the MAGIC BUTTON that I mentioned earlier must be activated through the accompanying application.

You can also save up to four different custom presets, one for listening to podcasts in the shower (it’s not just me, right?) and several others for when you’re hanging out at the beach with friends. Besides, UE also allows you to connect speakers together. You can connect up to 150 different UE speakers into one system, as long as they have the PartyUP feature.
