Margules U4 Planar Magnetic Headphones

The Beginning of True Listening

The Margules U4 represent a new reference in high-end personal audio.

Designed for audiophiles, musicians, engineers, and music lovers who seek far more than volume or artificial excitement, U4 reveals recordings with tonal balance, harmonic texture, spatial precision, and true musicality.

Its architecture combines high-resolution planar magnetic technology, premium materials, and handcrafted construction to create an intimate and deeply immersive sonic experience.

ANA™ (Aligned Neuro-Acoustics) PHILOSOPHY

At Margules, we understand that music is not experienced through specifications alone.

That is why ANA™ (Aligned Neuro-Acoustics) prioritizes the elements that truly shape human perception:

• Preservation of harmonic structure
• Temporal coherence
• Spatial stability
• Natural timbre
• Living microdynamics
• Reduced listening fatigue
• Emotional connection to the performance

The result is a sound that feels more organic, believable, and musically satisfying.

PLANAR MAGNETIC TECHNOLOGY

Speed, Resolution, and Control

At the heart of U4 is a large-format Planar Magnetic transducer (70 x 95 mm) with an ultra-light 21 micron PET diaphragm, driven uniformly by Neodymium N50SH magnets.

This architecture offers significant advantages over many conventional dynamic designs:

• Extremely fast transient response
• Very low distortion
• Higher microdetail resolution
• Deep and controlled bass
• Excellent instrument separation
• Lower dynamic compression
• More stable soundstage

When moving mass is minimized, music is reproduced with greater precision and natural realism.

HOLOGRAPHIC IMAGING

Music in Front of You

One of the most remarkable qualities of the Margules U4 is their ability to project an open, three-dimensional soundstage.

Thanks to the speed of the planar diaphragm, linear behavior, and preservation of spatial micro-information, the listener perceives:

• Real width
• Front-to-back depth
• Air between instruments
• Precisely focused vocals
• Distinct musical layers
• Authentic room ambience

Music no longer feels trapped inside the headphones—it appears before you.

HANDCRAFTED SOLID WOOD CONSTRUCTION

Each ear cup is machined from a single piece of selected wood and hand-finished to create a naturally elegant and exclusive appearance.

Benefits include:

• Structural rigidity
• Natural resonance control
• Unique grain patterns
• Organic visual character
• Premium handcrafted identity
• No two units are exactly alike

COMFORT & ERGONOMICS

Over-Ear Open-Back Design

The circumaural square geometry fully surrounds the ear for superior comfort and natural acoustic openness.

Suspended Headband System

Weight is distributed over the head through an engraved leather suspension strap rather than directly on the ears.

This reduces pressure points and improves comfort during long listening sessions.

Replaceable Premium Ear Pads

The cushions are designed for softness, long-term durability, and easy replacement.
