The Ultimate Ears HYPERBOOM is the largest and loudest portable Bluetooth speaker in the Ultimate Ears lineup. Its 23-hour battery life and IPX4 rating for water resistance make it a great choice for outdoor gatherings, so you can blast tunes all day without worrying about charging. You can easily switch between different Bluetooth devices at the press of a button if you and a friend want to take turns DJing, and there's an adjustable EQ available through the companion app to customize the sound. There's even a handy carrying strap so you can bring it around with you one-handed.
Our Verdict
The Ultimate Ears HYPERBOOM is very good for music. This speaker has a generally balanced sound, though a boost in the low-mids that thickens bass lines can also make acoustic instruments sound a little muddy. A slight treble boost adds extra sheen and sparkle, and it has an Adaptive EQ room-correction feature that'll tailor the sound to the environment. It gets remarkably loud without much compression, too. The Ultimate Ears app even offers a full graphic EQ and presets to further customize its sound to your liking.

The Ultimate Ears HYPERBOOM is decent for videos and movies, though it's designed more for streaming video from a device than for home cinema use. Though it struggles to reproduce the rumbly low bass found in action-packed movie scenes, the dialogue remains fairly clear, though the boost in the low-mids can make voices sound a touch muddy. It sounds fairly consistent from different angles, can play stereo content, and gets remarkably loud without a lot of compression. Also, its latency on iOS and Android devices over Bluetooth is low enough that you won't encounter sync issues while watching video.

Popular Speaker Comparisons
The Ultimate Ears HYPERBOOM is a large portable Bluetooth speaker with an outstanding battery life of over 23 hours. It can get louder than its more portable sibling, the Ultimate Ears EPICBOOM, without the audio becoming overly compressed. While you can't bring it around on a hike, its battery life is significantly longer. That said, it can't produce as much low bass as speakers like the JBL Boombox 3, which is a better choice for fans of bass-heavy music like EDM and hip-hop.

The Ultimate Ears HYPERBOOM is a more premium speaker than the Ultimate Ears EPICBOOM. The HYPERBOOM offers better sound quality since it produces more low bass and can get louder. Its battery life is longer-lasting, too, and it has lower latency over Bluetooth. That said, it's larger than the EPICBOOM and not quite as well-suited for outdoor use.
The JBL Boombox 3 and the Ultimate Ears HYPERBOOM are similar speakers with different strengths. The Boombox 3 can produce deeper bass than the HYPERBOOM and offers 5 extra hours of battery life, for a total of almost 30 hours. It's better built with an IP67 rating for dust and water resistance, certifying it as dust-tight and submersible to a depth of up to 1 meter for 30 minutes. That said, the HYPERBOOM is a bit smaller and offers better directivity. If you prefer a better-built speaker that can produce deeper bass, go for the JBL. If you tend to blast your music and want cleaner audio at max volume, go for the Ultimate Ears instead.
The Ultimate Ears HYPERBOOM is the better speaker overall compared to the Bose S1 Pro System. The Ultimate Ears can play stereo content without downmixing it to mono, and its directivity is a bit better. Also, it comes with a graphic EQ and presets, so you can customize its sound to your liking.
The Ultimate Ears HYPERBOOM is a slightly better speaker than the JBL PartyBox 310, though they have different strengths. The Ultimate Ears has fewer compression artifacts at max volume and better directivity performance. It's also more portable than the JBL. However, the JBL can produce a much deeper low bass and gets louder than the Ultimate Ears. It also has inputs for connecting a mic or guitar.
