TANCHJIM NORA 

> DMT5 Dual Chamber, Dual-Magnetic-Circuit Driver
> Ultra-Smooth Acoustic Cavity
> Array Diffusion Structure
> Optimized Venting For Airflow
> Rear Helmholtz Resonator Cavity

> Tanchjim's First-Ever Hi-Fi Monitor Earphone
> Based on the balanced tuning favored by audiophiles, NORA enhances vocals and treble insturments for crisp, detailed, and fatigue-free sound. The lightweight, ergonomic design ensures lasting comfort for extended listening.

> Lightweight Build
> The sound chamber is made from medical-grade transparent resin, while the front plate features a metal frame and sapphire glass - offering a snug, lightweight fit and a refinded, crystal-clear aesthetic.

> Waveguide Faceplate Inspired By Our Flagship Model
> Curved waveguide ripples on the inner faceplate reduce sound loss and improve treble transmission and resolution for a more detailed sound.

> Redesigned External Pressure Venting
> Resists clogging and offers improved pressure relief, keeping ear canal airflow balanced and sound clear - ideal for extended wear.

> DMT5 Architecture Unit: Outstanding Dynamic Performance
> The DMT5 dynamic driver pairs a PU suspension with a DLC composite dome to deliver punchy, elastic bass and clear, natural mids and highs. Harmonic distortion is minimized, ensuring crisp, fast transients and refined detail.

> High-purity Detachable Cable With Interchangeable Plugs
> Crafted with thick silver-plated high-purity copper, the cable supports swappable 3.5mm and 4.4mm plugs for broad compatibility.

> Rear Cavity With Helmholtz Resonator Design
> A semi-open rear cavity with Helmholtz resonance enhances the 3k-4.5khz range for greater vocal clarity - perfect for music enjoyment and live monitoring alike.

> Ultra-smooth Acoustic Chamber Surface Technology
> The ultra-smooth chamber surface enhances vocal and treble detail, enabling seamless wave transmission and minimizing distortion from multiple relfections.

> Array-style Turbulence Control Structure
> Engineered to control wave diffusion, this physical structure enhances direct sound clarity and delivers a cleaner, more immersive listening experience.

> Authentic, Natural Sound Signature
> Distortion as low as 0.049% @ 1kHz (94dB)

Descriptions:

> Lightweight, Snug Fit With A Crystal-Clear Finish
> Designed for long listening sessions and professional monitoring, NORA features a lightweight medical-grade resin cavity with 316L stainless steel and sapphire glass faceplate - offering lasting comfort and a refined, premium feel.

> Versatile For Multiple Monitoring Applications
> With a wide frequency range and ultra-low distortion, NORA separates instrument resonance and overtones with precision, preserving every detail. It captures vocal nuances - from breath transitions to sibilants - with natural, balanced density.

> Waveguide Faceplate From Our Flagship Driver
> Using finite element analysis (FEA), the waveguide's curved ripples are optimized to improve modal distribution and treble energy transmission. CNC-machined from brass, its special inner ripples control vibration angles, boosting treble effiecieny by ~10% without added power, reducing loss, and enhancing resolution.

> Array Acoustic Diffusion System
> Working with the waveguide faceplate, the front cavity's array-style turbulence structure limits unwanted lateral diffusion, refining direct sound quality for a cleaner, purer listening experience.

> Ultra-smooth Inner Chamber Surface Technology
> High-frequency waves are easily affected by surface irregularities. TANCHJIM's ultra-smooth chamber design minimizes inreference, prevents standing waves, and reduces transmission loss - resulting in smoother highs and improved detail in vocals and instruments.

> Simulations show linear airflow with low turbulence and minimal loss. NORA's triple-stage front cavity system - waveguide control, turbulence reduction, and ultra-smooth cavity - optimizes the sound path for exceptionally pure output.
> With a flagship DMT5 dual-chamber, dual magnetic driver, NORA's powerful magnetic system delivers outstanding efficiency and performance.

> Core Driver Unit
> NORA's DMT5 dynamic driver features a PU suspension and composite diaphragm for extended excursion and dynamic range. PU damping absorbs excess vibration for elastic bass and controlled highs, while the DLC dome delivers high rigidity, low mass, and exceptional treble extension with clean transients.

> Rear Helmholtz Resonator Chamber Design
> THe semi-open rear cavity, with an FEA-optimized L-shaped Helmholtz chamber, precisely controls air-flow to boost 3k-4.5kHz energy - delivering clearer, smoother vocals.
> FEA simulations show the semi-open cavity producing smooth, layered airflow for efficient sound dispersion - yielding silky treble, deep bass, and precise rebound.

> New In-ear Pressure Relief For Long-term Comfort And Stability
> TANCHJIM redesigned the vent system - guided by auricle modeling and testing -  to prevent clogging, maintain pressure balance, and preserve clear, consisent sound during extended listening or monitoring.

> True-to-source Sound, Ultra-low Distortion
> Using FEA-based dynami correction and ear model testing, TANCHJIM optimized NORA to avoid harsh treble peaks in small ear canals - ensuring ideal comfortable sound for most listeners.
> With balanced tuning, NORA refines vocal and treble detail for smooth, clear sound. Moderate bass preserves mid-high transparency, and <0.5% distortion ensures faithful reproduction for both monitoring and music playback.

> Exceptional Passive Noise Isolation For Immersive Listenging
> Delivering up to 35dB passive noise isolation (B&K 5128 tested), NORA cuts ambient noise so you can enjoy music detail even in loud environments.

> Dust- & Water-resistant Acoustic Filter
> A DWR-coated acoustic mesh protects the driver from dust and moisture while softening treble harshness. Both the nozzle mesh and internal damping filters use this coating for enhanced long-term durability.

> Signature TANCHJIM Comfort
> NORA's ergonomic desingn aligns with the ear canal for a direct, low-reflection sound path. Balanced weight distribution across the concha and earhook reduces pressure points, ensuring stable, all-day comfort.

> High-purity Detachable Cable System
> Featuring LITZ composite braiding and thick silver-plated OFC cores, the cable is flexible, tangle-resistant, and durable. TANCHJIM's custom 4-pin connector with gold-plated copper pins ensures low resistance and high-fidelity signal transfer.
> Includes both 3.5mm and 4.4mm plugs for single-ended or balanced outputs.
