Meanwhile, UE (Ultimate Ears), a brand under Logitech, has carved its reputation through innovative speaker design and powerful 360-degree sound. Its Boom 2 model took the world by storm with waterproof capabilities and unmatched outdoor performance.
So how do the JBL Flip 4 and UE Boom 2 stack up against each other? Let’s dive deeper into each aspect.

Design and Features
JBL Flip 4 retains the cylindrical shape of its predecessors but refines the design with durable mesh fabric and soft silicone grips. Weighing just 515g, it’s compact, portable, and ideal for both indoor and outdoor use. The passive bass radiators on each end enhance the low-frequency response, but they’re somewhat exposed — so a drop on a hard surface might cause damage.
Buttons for Bluetooth pairing, play/pause, and volume are tactile but lack backlighting, which can be inconvenient in dark environments. Still, the Flip 4’s design balances functionality with elegance.
UE Boom 2, on the other hand, continues its iconic cylindrical aesthetic. Wrapped in a rugged fabric and rubberized exterior, it’s IPX7-rated, meaning it can survive being submerged in 1 meter of water for up to 30 minutes. The volume buttons are large and easily accessible, though they require a firm press. The speaker’s color combinations are fun and eye-catching — perfect for those who like to make a style statement.
Build Quality and Durability
Both speakers are designed for outdoor adventures, but the UE Boom 2 clearly wins in terms of ruggedness. You can drop it, splash it, or take it to the pool without worry.
The JBL Flip 4 is also waterproof but feels more suited for tabletop or indoor party use. Its mesh fabric can get dirty faster, while UE Boom 2’s smooth rubber and fabric combination are easier to clean.
Battery Life and Charging Performance
Battery life is a crucial factor when comparing portable speakers.
- JBL Flip 4 comes with a 3000mAh battery offering 12 hours of playback.
- UE Boom 2 packs a slightly bigger punch with 15 hours of continuous playtime.
Charging times differ as well — Flip 4 takes 3.5 hours for a full charge, while Boom 2 only needs 2.5 hours.
For long road trips, parties, or travel, UE Boom 2’s longer battery life makes a noticeable difference.
Sound Performance and Audio Quality
JBL Flip 4:
Flip 4’s dual 40mm drivers produce 16W of total power output. The sound is crisp, with deep bass and decent treble balance. It’s ideal for pop, EDM, and hip-hop lovers who appreciate strong low-end performance.
However, at maximum volume, mids and vocals may slightly distort. At 70–80% volume, the sound remains clear and balanced, delivering impressive room-filling sound for its size.
UE Boom 2:
UE Boom 2 provides 360° audio projection, ensuring consistent sound quality from every direction. The mids are more pronounced, and treble clarity is excellent. Bass is tight, though slightly less thumping than JBL Flip 4.
What sets Boom 2 apart is its open soundstage, making it perfect for outdoor environments or gatherings. You can even pair multiple UE speakers for stereo or party mode.
Connectivity and Smart Features
Both speakers offer Bluetooth connectivity, but UE Boom 2 steps ahead with Bluetooth 5.0, providing better range and faster pairing.
JBL Flip 4, however, offers dual device pairing, allowing two users to connect simultaneously — a great feature for group playlists.
UE Boom 2 also includes tap controls — you can tap the top of the speaker to play/pause or skip tracks, though it might require some practice.
Water Resistance and Outdoor Use
Both models are IPX7 certified, which means they can survive full submersion in water for up to 30 minutes.
However, the UE Boom 2 performs better in rugged outdoor conditions thanks to its tougher shell and tight-sealed ports. It’s the perfect speaker for beach days, hikes, and pool parties.
JBL Flip 4 is more “splashproof” than rugged — great for use near water but not as impact-resistant.
