Choosing Between the Ultimate Ears EPICBOOM and Marshall Emberton III: A Complete Guide

When it comes to portable Bluetooth speakers in 2024, we're seeing some fascinating developments in how manufacturers balance sound quality, portability, and features. Let's dive into a detailed comparison of two notable contenders: the Ultimate Ears EPICBOOM ($299) and the Marshall Emberton III ($169), which represent different approaches to portable audio.

Understanding Today's Portable Speakers

The portable speaker market has evolved significantly from the early days of tinny, battery-hungry devices. Modern speakers offer impressive sound quality, rugged durability, and smart features that were unimaginable just a few years ago. These two speakers, while both technically "portable," target different use cases and user needs.

The EPICBOOM, released in late 2023, represents Ultimate Ears' push into higher-power portable audio, while the Emberton III, launched in early 2024, continues Marshall's tradition of compact but capable speakers with classic styling.

Sound Quality Deep Dive

Power and Volume

The EPICBOOM makes its intentions clear with its larger drivers - two 45mm mid-high frequency transducers paired with a substantial 120mm woofer. This configuration delivers up to 94 dBC of sound pressure level (think "loud enough for a backyard party"). In contrast, the Emberton III uses two 2-inch full-range drivers with passive radiators, focusing on balanced sound rather than raw power.

Audio Performance

Both speakers implement interesting approaches to sound distribution:

The EPICBOOM uses what Ultimate Ears calls 360-degree sound projection, which I've found particularly effective in outdoor settings. The speaker actually floats in water while playing, making it perfect for pool parties. Its adaptive EQ technology adjusts the sound signature based on the environment - a feature that's particularly noticeable when moving from indoor to outdoor spaces.

The Emberton III employs Marshall's "True Stereophonic" technology, which creates an impressive stereo image regardless of speaker orientation. During testing, this works surprisingly well for such a compact device, though it can't match the EPICBOOM's raw power.

Bass Response

Here's where size matters significantly. The EPICBOOM's larger woofer delivers noticeably more low-end punch, especially in outdoor settings. The Emberton III compensates with its "Dynamic Loudness" feature, which adjusts tonal balance based on volume level, but physics are physics - it simply can't move as much air as its larger competitor.

Portability and Design

The contrast in design philosophy becomes apparent when comparing physical dimensions:

EPICBOOM:

• Height: 241mm
• Weight: 1.979kg
• Design: Modern, rugged aesthetic

Emberton III:

• Height: 76.9mm
• Weight: 0.67kg
• Design: Classic Marshall amp styling

The Emberton III is genuinely portable - it fits in a jacket pocket or small bag. The EPICBOOM requires more commitment to transport, though its integrated strap helps. Both feature IP67 water and dust resistance, meaning they can handle submersion in 1 meter of water for 30 minutes.

Battery Life and Connectivity

Battery technology has seen significant improvements in recent years:

• EPICBOOM: 17 hours of playback
• Emberton III: 32+ hours of playback

Both use Bluetooth 5.3, but implement it differently. The EPICBOOM offers Ultimate Ears' "PartyUp" feature, allowing connection with other UE speakers for expanded sound. The Emberton III is Bluetooth LE Audio-ready and will support Auracast (a new technology for broadcasting to multiple compatible devices) through a future update.

Special Features and Technology

EPICBOOM Standouts:

• Adaptive EQ with customizable settings
• Floating design for pool use
• One-touch NFC pairing
• PartyUp multi-speaker synchronization
• Outdoor Boost mode for open-air environments

Emberton III Innovations:

• True Stereophonic sound technology
• Dynamic Loudness compensation
• Future Auracast support
• Built-in microphone for calls
• Stack multiple units vertically

Real-World Performance

In practical use, these speakers excel in different scenarios:

The EPICBOOM shines at:

• Outdoor gatherings
• Pool parties
• Large room filling sound
• Situations requiring maximum volume
• Custom sound adjustment

The Emberton III excels at:

• Personal listening
• Desktop or small room use
• Travel and commuting
• Extended playing time
• Balanced sound at moderate volumes

Value Proposition

When considering value, we need to look beyond just the price difference:

The EPICBOOM at $299 offers:

• Significantly more power
• Better bass response
• More flexible EQ options
• Superior outdoor performance

The Emberton III at $169 provides:

• Nearly twice the battery life
• More portable form factor
• Classic design
• Future-ready Bluetooth features

How to Decide

Choose the EPICBOOM if you:

• Frequently host outdoor gatherings
• Need maximum volume output
• Want the ability to float your speaker
• Prefer deep bass response
• Plan to connect multiple speakers

Choose the Emberton III if you:

• Prioritize portability
• Need extended battery life
• Prefer a classic aesthetic
• Want a more budget-friendly option
• Use your speaker primarily for personal listening

Final Thoughts

Both speakers represent excellent choices within their respective niches. The EPICBOOM is an outdoor party powerhouse that sacrifices some portability for performance, while the Emberton III offers a more balanced approach focused on personal use and portability.

For most users, the decision will come down to intended use case rather than pure technical specifications. The EPICBOOM's higher price point is justified if you need its additional power and features, while the Emberton III offers exceptional value for personal listening and travel use.

Remember that both speakers carry solid water resistance ratings and strong build quality - they're designed to last regardless of which you choose. Your decision should ultimately align with how you plan to use the speaker most often, as both excel in their intended roles.
