  • 【DMT5 Flagship Dynamic Driver, CNC Precision Acoustic Wave Guide】Features DMT5 dual magnet, dual chamber structure. THD (Total Harmonic Distortion) at 1kHz achieves less than 0.056% at 94dB playback, delivering extremely faithful tonal reproduction and a vast soundstage. Furthermore, it incorporates a high-precision waveguide made of brass, CNC-machined based on FEA analysis, which improves high-frequency conduction efficiency and enables an open and delicate high-frequency response.
  • 【TANCHJIM x Rational HiFi】 Built-in DSP sound profile tuned by Rational HiFi. Mr. GFSH119, founder of Rational HiFi, pursues faithful sound reproduction. After extensive listening, a dedicated DSP preset was created for the FISSION collab. This preset is unique to the FISSION collab. Rational HiFi’s tuning focuses on low-frequency optimization by setting F0 relatively low, for greater low-frequency energy and wider dynamic range. The housing is optimized to avoid overly thick vocals. This design delivers balanced, natural sound.
  • 【4-Stage Filter × 3 Nozzle Combinations, 12 Customizable Sounds】Features a 4-stage adjustable analog filter knob, allowing seamless switching between four sound modes: “Pops,” “Vocal,” “Ambient,” and “Monitoring.” Additionally, it comes with three different material nozzles (brass/stainless steel/titanium), which can be freely swapped to enjoy 12 distinct sound styles. This versatile tone adjustment capability enriches and expands your listening experience.
  • 【Dual-Layer Filter Design with Guided Airflow Venting Structure】A dual-layer filter system: outer stainless steel mesh, inner layer with DWR coating. This prevents dust while maintaining acoustic transparency. Using finite element-based acoustic-fluid simulation, the vent is optimally positioned via rear cavity structure and volume ratio analysis. By mitigating ear occlusion effects, FISSION achieves higher sound field density for a more realistic, immersive auditory experience.
  • 【Lightweight Aluminum Alloy Housing, Comfortable Fit】The FISSION body utilizes lightweight aluminum alloy material, featuring a teardrop-shaped sapphire glass accent on the front panel. It offers excellent wear and corrosion resistance. Furthermore, its ergonomic design, based on data from over 3,000 ear shapes, ensures a deep, comfortable fit and optimal insertion angle. This enables more natural acoustic coupling, allowing high-frequency response to resonate smoothly.
