As we dive into 2024's portable audio offerings, two standout speakers have captured attention for different reasons: the Ultimate Ears EVERBOOM ($249) and the Bose SoundLink Flex ($149). Let's explore what makes each unique and who they're best suited for.
Portable Bluetooth speakers have come a long way from their tinny, battery-hungry predecessors. Today's models combine sophisticated audio engineering with rugged durability and smart features. The latest releases from Ultimate Ears and Bose showcase just how far we've come.
The EVERBOOM, released in late 2023, represents Ultimate Ears' latest innovation in their popular BOOM series. Meanwhile, Bose's SoundLink Flex, launched in fall 2024, builds on their reputation for balanced audio in a refined package.
The EVERBOOM takes a unique approach with its cylindrical design and 360-degree sound projection. Using two 56.6mm full-range drivers and dual passive radiators (which help enhance bass response without requiring additional power), it achieves an impressive 90 dBC output. This means it can easily fill a large backyard or pool area with clear, energetic sound.
The SoundLink Flex utilizes a more traditional forward-firing design but incorporates Bose's proprietary PositionIQ technology. This clever system uses internal sensors to detect the speaker's orientation and automatically adjusts the EQ (equalizer settings) for optimal sound whether it's standing upright, lying flat, or hanging from its utility loop.
In testing both speakers, clear differences emerge:
EVERBOOM strengths:
SoundLink Flex advantages:
With a 20-hour battery life, the EVERBOOM significantly outlasts the SoundLink Flex's 12-hour rating. Both charge via USB-C, but the EVERBOOM's longer runtime makes it more suitable for weekend trips or all-day outdoor events.
Both speakers feature IP67 ratings, meaning they're:
The EVERBOOM adds flotation capability, making it ideal for pool parties. The SoundLink Flex, while equally waterproof, doesn't float but compensates with a more compact, damage-resistant design.
Despite its superior volume output, the EVERBOOM's larger size (8.1" tall, 2.12 lbs) makes it less convenient for everyday carry. The SoundLink Flex (7.9" x 3.6" x 2.1", 1.3 lbs) fits more easily in a backpack or bag, making it the better choice for regular commuters or travelers.
The Ultimate Ears app offers more extensive customization for the EVERBOOM, including:
Bose's Connect app provides:
The EVERBOOM's PartyUp feature allows connection with other Ultimate Ears speakers, creating an expandable sound system. The SoundLink Flex can pair with other Bose speakers but offers fewer configuration options.
The EVERBOOM justifies its higher price through:

The SoundLink Flex makes more sense if you:
Both speakers represent the current state of the art in portable audio, but they serve different needs. The EVERBOOM excels as a powerful party speaker with impressive volume and battery life, while the SoundLink Flex offers a more versatile everyday companion with excellent sound quality for its size.
Consider your typical listening environment and how you'll most often use the speaker. For apartment dwellers who occasionally take their music outside, the SoundLink Flex likely offers everything needed. But if you're planning regular outdoor gatherings or want to fill larger spaces with sound, the EVERBOOM's additional power and features make it worth the premium.
