Velvety-Smooth Touch. Infinite Sound Within.
U-XUE is a premium true wireless earbud designed for immersive everyday listening. Featuring a hybrid driver system with UM proprietary bone conduction technology, U-XUE delivers a spacious, detailed sound experience in a compact, comfortable form.
Powered by a Qualcomm chipset and supported by intelligent sound control, U-XUE brings high-fidelity audio, stable connectivity, and effortless usability together in one refined design.
Hybrid Acoustic Architecture
Dynamic · Balanced Armature · Bone Conduction
U-XUE is built around a true three-way hybrid system that integrates air conduction and bone conduction into a coherent acoustic whole. Each driver is purpose-tuned, then precisely aligned through a high-precision crossover system to preserve phase accuracy and tonal balance.
10 mm Carbon Nanotube Dynamic Driver
A high-impedance carbon nanotube diaphragm provides exceptional stiffness and low distortion. Driven by a high-power magnetic structure, it delivers deep, layered bass with excellent control, while maintaining a natural and expressive midrange.
Precision Balanced Armature Driver
Dedicated to high-frequency reproduction, the balanced armature driver is tuned for clarity and extension. Fine details such as string harmonics and percussive overtones are rendered cleanly, without harshness.
UM Proprietary Bone Conduction Unit
A silver-palladium piezoelectric bone conduction driver transmits sound vibrations directly through the skull. When combined with traditional air conduction, it expands spatial perception and enhances micro-detail, allowing instrument resonance and subtle textures to emerge more clearly.
Powered by Qualcomm
At the core of U-XUE is a Qualcomm chipset chosen for signal stability, efficiency, and low-latency performance. High-resolution audio support extends up to 24-bit / 96 kHz, with aptX Lossless enabling greater transparency, dynamic range, and detail over Bluetooth.
Latency is reduced to approximately 38 ms, ensuring accurate lip-sync for video and precise positional cues during gaming, without compromising audio quality.
UM SmartSound App
The UM SmartSound app provides direct control over U-XUE’s acoustic behavior.
• Switch sound modes instantly
• Customize EQ to suit personal preference
• Adapt tuning for different environments and use cases
All adjustments are designed to preserve tonal balance and resolution, rather than artificially coloring the sound.
Sound Modes
Hi-Fi Mode
A reference-oriented tuning that prioritizes clarity, balance, and natural timbre. Bass remains controlled and textured, while treble stays open and well-extended for realistic reproduction.
Ambient Mode
Selectively introduces environmental sound while maintaining tonal integrity. Useful for commuting or outdoor listening without removing the earbuds.
Assistive Listening Mode
Enhances low-level detail and vocal presence, improving intelligibility of distant or quiet speech. Designed as a practical listening aid without altering core tonal balance.
Amplifier Topology & Battery Life
U-XUE allows users to select between two amplifier architectures, balancing sound character and endurance.
Class AB Amplifier
Prioritizes smoothness and natural harmonic structure. Delivers up to 5 hours of playback on the earbuds, plus 10 hours with the charging case.
Class D Amplifier
Optimized for efficiency and extended listening. Provides up to 6 hours on the earbuds, plus 12 hours with the charging case.
Battery life is measured using AAC at 50% volume under laboratory conditions. Actual results may vary depending on usage and environment.
Crystal-Clear Calls
A high-sensitivity directional microphone array captures speech with precision. AI-based noise reduction minimizes wind noise and ambient interference in real time, while stable Bluetooth connectivity maintains consistent call quality.
Smart In-Ear Detection
Playback begins automatically when the earbuds are worn and pauses when they are removed. High-precision sensors ensure reliable, intuitive operation without manual input.
Water-Resistant Construction
An IP55-rated design with precision-sealed seams protects U-XUE from sweat and splashes. Acoustic performance remains stable during workouts and outdoor use.
Comfort & Fit
Skin-Feel Coating
A soft matte surface provides a smooth, skin-like tactile experience. The coating resists scratches and sweat while maintaining a refined, understated finish.
UM Umbrella Liquid-Silicone Eartips
Crafted from food-grade liquid silicone, these eartips are soft, flexible, and gentle in the ear. The umbrella-shaped design ensures a secure seal without pressure buildup.
• Vent Type: Six micro-vents improve airflow, reduce heat, and allow limited environmental awareness
• Non-Vent Type: Increased isolation for deeper immersion
Both styles are included in S, M, and L sizes.
