The Ultimate Ears EPICBOOM is a portable Bluetooth speaker with a premium design. It's suitable for listening both inside and outside, with an IP67 rating for dust and water resistance to protect it against the elements. It's really customizable, too, with the more basic Outdoor Mode to enhance sound when you're listening in larger and more open spaces, as well as a graphic EQ and presets available in its companion app. Plus, its Adaptive EQ automatically optimizes the sound based on the unique acoustics of your room.
The Ultimate Ears EPICBOOM is satisfactory for music. This speaker has an Adaptive EQ tool that optimizes the sound based on your room's unique acoustics. With it on, it reproduces a little extra warmth in the bass range and some extra sparkle in the treble, which is ideal for genres with lots of highs and lows, like rock and pop. Still, its graphic EQ and presets allow you to change its sound if you want something different. It also gets loud enough for most rooms, though there's some compression at max volume.
The Ultimate Ears EPICBOOM isn't designed for watching movies, but it's a fair pick if you just want to stream videos on a paired smartphone. Latency is low when paired to iOS devices over Bluetooth, and while it's a little higher on Android devices, you still don't notice lip-synching issues. The speaker reproduces clear dialogue, too, and it brings some punch to the bass. However, it's not as rumbling or as loud as more dedicated home theater speakers.
The Ultimate Ears EPICBOOM is very good for podcasts. This speaker offers a pretty balanced mid-range, so voices reproduce with clarity and accuracy. It gets loud enough to fill most rooms in your home with clear sound, and thanks to its built-in strap, you can move it with you from room to room during longer episodes. If you place it in the center of the room, you get consistent sound from all angles, too, thanks to its 360-degree design.
This speaker doesn't support voice assistants.
The Ultimate Ears EPICBOOM is good for outdoor use. It's rated IP67 for dust and water resistance, and the manufacturer says it can withstand some drops and falls without issue. This speaker has a solid and sturdy build, and while it's on the larger side, its built-in strap makes it easier to transport. You can even use its Outdoor Mode preset to enhance audio across larger and more open spaces like your backyard. Its battery life ranks on the lower side, though.
The Ultimate Ears EPICBOOM is available in either Charcoal Black or Cotton White. We tested the Charcoal Black variant, and you can see the label here.

The Ultimate Ears EPICBOOM is a premium speaker positioned between the Ultimate Ears HYPERBOOM and the Ultimate Ears MEGABOOM 3 in size and sound quality. It comes with many of the same features as the HYPERBOOM, including an Adaptive EQ room calibration tool to optimize its sound to your room's unique acoustics. It doesn't get as loud, though, and there's more compression at max volume.
The Ultimate Ears EPICBOOM is a more premium alternative to the Ultimate Ears MEGABOOM 3. The EPICBOOM is a larger speaker, and it can bring a more extended low-bass. Also, it gets louder and has an Adaptive EQ room correction tool, which the MEGABOOM lacks. If you want a more portable device, you may prefer the MEGABOOM.
The Ultimate Ears HYPERBOOM is a more premium speaker than the Ultimate Ears EPICBOOM. The HYPERBOOM offers better sound quality, especially regarding dynamics, as it can get louder with less compression at max volume. Its battery life is longer-lasting, too, and it has lower latency over Bluetooth. It's larger than the EPICBOOM and not quite as well-suited to outdoor use.
The JBL Boombox 3 is a better choice for music than the Ultimate Ears EPICBOOM. The JBL reproduces a bit more low-bass, so you feel more thump and rumble in the mix. It doesn't get quite as loud but has less compression at max volume. Plus, its battery life lasts longer. The Ultimate Ears has some additional customization tools, like an Adaptive EQ room calibration tool and more preset modes.
The Sony SRS-XG300 and the Ultimate Ears EPICBOOM each have different strengths. The Sony has a boombox-style design, and it lets you pair with voice assistants from your smartphone. Its battery life is longer-lasting, too. However, its sound quality isn't as good as the Ultimate Ears, which has a better soundstage. Plus, the Ultimate Ears has more sound customization tools, like a room correction feature called Adaptive EQ.
The Ultimate Ears EPICBOOM is a stylish speaker with a minimalist design. There are two large volume buttons on the front of the speaker, similar to the Ultimate Ears MEGABOOM 3. It's sleek enough to blend in with your home decor and rugged enough to take outdoors.
The speaker's build quality is excellent. It's sturdy and well-built, with a well-knit mesh fabric wrapping that doesn't seem prone to rips or tears. It's also rated IP67 for dust and water resistance, so it can withstand some exposure to the elements. According to the manufacturer, the rubber base contributes to the speaker's ability to withstand drops of up to one meter. There's also a cover for the USB-C charging port with a tight seal, which is nice.
The controls are clearly marked and easy to use. They offer good feedback, too, with audible cues when you turn the speaker on/off, activate Bluetooth pairing, and connect to a device. Plus, three LED lights about the volume button give a rough estimate of the battery level. There's feedback for max volume and when the speaker's battery is low. However, there's no audible feedback when you switch to Outdoor Mode, so you're limited to the LED light signals to keep track of that.
This speaker has a decent stereo frequency response. It reproduces a little extra warmth in the high-bass, which slightly muddies voices and lead instruments as it carries into the mids. There's a little extra brightness in the treble, too. You can always switch up its sound with its graphic EQ and presets in the Ultimate Ears app, too.
This speaker has a room calibration tool called Adaptive EQ that automatically adjusts the speaker's sound based on the unique acoustics of your space. We tested the speaker with this feature turned on. We didn't turn on any of the preset EQ modes, though. If you want to see a comparison of the different presets, take a look at the graph here.
This stereo speaker has an excellent soundstage. Thanks to its 360-degree design, it can reproduce consistent audio from all angles.
This speaker gets loud, though not as loud as the Ultimate Ears HYPERBOOM. There's a little more compression when you push it to max volume, too, which impacts the clarity of audio reproduction.
The manufacturer advertises a battery life of seventeen hours, though the speaker only lasted over seven hours in our tests. Battery life can vary depending on your usage habits, which may contribute to this discrepancy. The charge time isn't too long, and there's also a power-saving feature on hand to help conserve battery life.
The Ultimate Ears app is a handy way to control the speaker from your phone. It lets you access lots of different features, like a graphic EQ and presets, which are available as long as you're in Indoor Mode. You can also set a preset playlist from compatible music apps like Amazon Music, Spotify, and Apple Music. Plus, you can set alarms and pair the speaker with other compatible devices from the manufacturer. The Sticky PartyUp feature even lets you group multiple speakers that automatically go into Party Mode when you turn them on, so you don't need to group them together each time you use them. You can see a video of the app here.
This Bluetooth-compatible speaker is easy to pair with your devices. If you have an Android 8.0 device or higher, you can use NFC pairing to connect in no time at all. The manufacturer says you can pair it with up to two devices at a time, but during our tests, it disconnected the first device when we attempted to connect to a second one. Over iOS devices, latency falls within good limits, and while it's a little higher with Android devices, you still aren't likely to encounter lip-synching issues. Some apps compensate for latency differently, though.
