Whether you’re relaxing at home, hosting a party, or enjoying the outdoors, this high-performance speaker ensures immersive sound quality without compromise.

With innovative JumboBass™ technology, extended battery life, true stereo pairing, and a waterproof build, the EarFun UBOOM L is a perfect companion for audiophiles and adventurers alike. Unlike conventional portable speakers, it delivers impressive audio clarity, dynamic bass, and an optimized listening experience across different environments.

Let’s explore the outstanding features and benefits that make the EarFun UBOOM L an excellent choice for portable wireless sound.

JumboBass™ Technology – Deep, Powerful, and Natural Sound

One of the standout features of the EarFun UBOOM L is its JumboBass™ Technology, which is engineered to enhance low-frequency response for richer, more powerful bass. Despite its compact size, this speaker delivers deep, natural bass that resonates through every beat, making your music feel more immersive.

Most portable speakers often lack deep bass, leading to flat or shallow sound profiles. The EarFun UBOOM L overcomes this challenge by implementing an advanced bass optimization system that boosts lower frequencies while maintaining balance in mids and highs, ensuring that every song sounds as vibrant and detailed as intended.

With JumboBass™, genres like EDM, hip-hop, rock, and classical music gain a depth that enhances the listening experience, offering studio-grade sound in a compact design.

High-Performance Audio Drivers and Dual Passive Radiators

To achieve its exceptional sound quality, the EarFun UBOOM L is equipped with two high-quality 2-inch full-range drivers, delivering balanced and distortion-free audio. These precision-engineered drivers work alongside dual passive radiators, ensuring that bass notes feel rich and resonant without overpowering other frequencies.

Unlike traditional speakers that struggle with muddy bass or weak treble performance, the dual passive radiators amplify deep tones while keeping vocals and instruments crisp and clear. The result is an immersive soundstage that lets you experience every song with full clarity.

Whether you are streaming music, watching movies, or gaming, the speaker maintains sharp details and dynamic depth across all frequencies.

True Stereo Pairing and Multi-Speaker Auracast Connectivity

The EarFun UBOOM L supports true stereo pairing, allowing users to connect two speakers wirelessly for enhanced audio depth and separation. This means left and right channel synchronization, producing a cinematic and immersive stereo experience for large spaces or outdoor events.

Additionally, the Auracast compatibility feature enables multi-speaker connections, allowing users to sync multiple JBL-compatible speakers and create a unified sound system across different rooms or locations.

This feature is perfect for parties, gatherings, or creating a surround-sound atmosphere, ensuring consistent, room-filling audio across multiple devices.

Versatile Audio Modes – Optimized Sound for Any Setting

The EarFun UBOOM L offers multiple listening modes, ensuring the best sound performance for different environments and content types:

Indoor Mode

This mode optimizes sound balance for enclosed spaces, delivering clearer vocals and refined bass without excessive amplification. It’s ideal for home use, workspaces, and casual listening, providing a pleasant and immersive experience without distortion.

Outdoor Mode

Designed for open environments, Outdoor Mode boosts overall volume and bass intensity to cut through ambient noise, ensuring powerful, crystal-clear sound outdoors. Whether you’re camping, hiking, or hosting a beach party, this mode guarantees that your music stays vibrant and well-defined.

Video Mode

For users watching movies or playing games, Video Mode reduces latency, ensuring perfect audio-visual synchronization. This eliminates sound delays between visuals and audio, making movies more immersive and gaming more responsive.

These modes ensure that whether indoors or outdoors, your listening experience is fully optimized.
