The Ultimate Ears BOOM 3 is a portable Bluetooth speaker that comes with a built-in hook so you can hang it from your bag or backpack when you're on the go. It's small and lightweight, and it has an IP67 rating for dust and water resistance, though we don't currently test for this. Unfortunately, its out-of-the-box sound profile is a bit uneven, and it doesn't get very loud. However, you can use the graphic EQ and presets in the Ultimate Ears app to help adjust its sound to your liking.
Our Verdict
The Ultimate Ears BOOM 3 is passable for music. Out-of-the-box, it has a bass-heavy sound profile, though it struggles to reproduce thumpy low-bass, which can be disappointing if you love bass-heavy genres like EDM. Vocals and lead instruments are present thanks to the neutral mid-range, but they can also sound a bit dull or veiled. Fortunately, you can customize its sound to your liking using the graphic EQ and presets in the Ultimate Ears app.
- Graphic EQ and presets.
- Lacks low bass.
The Ultimate Ears BOOM 3 is mediocre for videos and movies. While dialogue is clear due to its balanced mid-range, it can also sound a bit dark or dull due to the underemphasized treble. Also, it struggles to reproduce a thumpy low bass, so you don't really feel the deep rumbles in action-packed scenes. It doesn't get very loud, though audio reproduction is clear at max volume. That said, it has low latency with Android and iOS devices over Bluetooth, though some apps compensate for this differently.

The Ultimate Ears BOOM 3 and the Ultimate Ears BOOM 4 are, by and large, the same speaker with one difference that will appeal to many users: the previous generation charges via a micro-USB cable and the new generation opts for USB-C charging instead. Beyond this, differences in performance are marginal at best. The newer iteration features slightly more bass (though it's still far from bass-heavy) and a less rolled-off treble. That said, it has a slightly shorter continuous battery life. Users who already own the BOOM 3 and aren't desperate for USB-C charging would be advised to hang on to their current speaker.

It gets as loud as the JBL with less compression at max volume, resulting in cleaner audio at louder volume levels.

However, the JBL offers a better-balanced sound profile out-of-the-box and can produce a more extended low bass. It's a bit smaller in size, and you can pair it to up to two devices at a time, so you can easily switch between audio sources.
