We continuously focus on the needs of listeners and are dedicated to improving sound quality.

By leveraging our sound expertise, we have accumulated much R&D experience and incorporated much feedback in our continuous quest for improvement.

The culmination of this effort is the JT3 open-back headphones.

Large 50mm dynamic driver Relaxed sound, robust bass

The JT3 features a best-in-class 50mm dynamic driver. Its large size allows it to move more air with greater force, allowing it to deliver richly detailed sound with a vast soundstage and potent bass.

PEK+PU composite polymer diaphragm Combining strengths, for a beautiful sound

The diaphragm is crafted from a unique PEK and PU* composite that combines the rigidity of PEK with the flexibility of PU. This fusion of soft and hard materials ensures both a lightweight design and excellent sound performance. A built-in brass damping ring minimizes distortion and unwanted breakup, ensuring every nuance in the music is clearly reproduced.

*PEK (polyetherketone) is a ketone-based semi-crystalline thermoplastic known for its high rigidity as well as its excellent resistance to high temperatures and chemicals. PU (polyurethane) is a high- performance synthetic polymer material that blends the best qualities of rubber and plastic, providing exceptional strength and durability – making it suitable for a wide variety of uses.

Lightweight materials, mighty output

TIL voice coil former and CCAW voice coil

The JT3’s driver features a lightweight TIL former and a CCAW* voice coil. The TIL material has excellent strength and high-temperature resistance, preventing the voice coil from deforming during long listening sessions. The ultra-fine CCAW voice coil not only makes the diaphragm lighter but also boosts efficiency and sensitivity. The voice coil and former work together to improve the driver's sensitivity and its ability to reproduce details in the sound.

*TIL is a composite of glass fiber and polyimide, making it incredibly light, thin, and resistant to high temperatures. Since it's a non-metallic material, it is also free from magnetic field eddy current loss. CCAW is a unique material featuring a copper-clad aluminum core, giving it the ideal combination of aluminum's lightness and copper's excellent conductivity.

Powerful N52 magnets

High-quality magnets, strong dynamics

The JT3 is equipped with high-performance N52 magnets—the strongest in the industry. These magnets are the powerful driving force behind the driver, dramatically improving its responsiveness and overall performance.

Open-back design

Spacious sound, precise imaging

The JT3 employs an open-back design to recreate the feel of a natural listening environment. Such a design effectively eliminates pressure buildup and standing waves typically found in closed-back headphones, delivering a wide and immersive soundstage with accurate sound.

Angled drivers Clear sound, straight into your ear

The drivers are angled specifically to better fit the contours of the human ear. This not only ensures sound is delivered more effectively but also optimizes airflow within the earcup for better acoustics.

Velvet earpads Comfortably soft, detachable and washable

The earpads are crafted from elegant, smooth velvet and feature internal memory foam. The velvet is soft and comfortable to the touch, while its dense fibers ensure it remains wrinkle-free and highly durable. The pads being detachable and washable make cleaning and replacement a breeze, helping to ensure your headphones last for years.

Dual 3.5mm to 3.5mm cable with microphone Detachable design, more convenience

Crafted from palladium-plated oxygen-free copper wires, the cable is easy to use with dual TRS interchangeable connectors and an intuitive “left blue, right red” identification system. The included 3.5mm to 6.3mm adapter allows you to connect to a variety of devices. Furthermore, the cable itself is detachable, allowing you to switch cables to connect to an even wider range of sources, including both single-ended and balanced outputs. With its in-line microphone and controls, you can manage calls, play games, and more, offering greater versatility.

Aluminum-magnesium alloy grille Lightweight and free-flowing, refined feel

The outer shell is crafted from a lightweight, smooth-textured aluminum- magnesium alloy, featuring a perforated grille design that is both beautiful and light. Thanks to the open-back design, sound escapes the earcup uniformly, providing a spacious yet natural soundstage.

Attention to detail

Finely crafted, comfortable to wear

The JT3’s comfort and fit also reflect its craftsmanship and attention to detail. Behind its simple appearance is a carefully thought-out design and solid, reliable quality.
