Bunny

TANCHJIM Bunny – Dual-Chamber Dynamic In-Ear Monitors with DMT4 Ultra Technology & DSP App Tuning

Delivering exceptional high-fidelity sound in an ultra-budget, ergonomic footprint, the TANCHJIM Bunny sets a new standard for entry-level IEM performance. Engineered around TANCHJIM’s proprietary DMT4 Ultra dual-chamber dynamic driver, the Bunny pairs a titanium-plated dome composite diaphragm with an acoustic labyrinth maze structure. The result is deep, textured bass, articulate mids, and smooth high-frequency detail with an exceptionally low harmonic distortion rate ($<0.05\%$). Available in both traditional 3.5mm analog and USB Type-C DSP configurations, the Bunny offers seamless high-resolution audio for music, media, and competitive gaming.

Key Features:

• DMT4 Ultra Dual-Chamber Dynamic Driver: Powered by an inner double-magnetic circuit and dual acoustic cavities to optimize air pressure, delivering clean midrange separation and tight, controlled low-end impact.

• Titanium-Plated Dome Composite Diaphragm: Utilizes a PU suspension edge combined with a Ti-plated PET dome. This lightweight yet ultra-rigid diaphragm eliminates unwanted break-up modes for effortless vocal clarity and ultra-fast transient speed.

• Patented Acoustic Labyrinth Back-Cavity: Incorporates a maze-like internal cavity structure and a low-distortion waveguide faceplate that minimizes high-frequency resonance while extending sub-bass depth.

• Detachable 0.78mm 2-Pin Silver-Plated Cable: Built with a parallel Litz-braided oxygen-free copper (OFC) silver-plated wire. The standard 0.78mm 2-pin interface allows for easy cable swapping or Bluetooth adapter upgrades.

• Smart App EQ Tuning (Type-C / DSP Version): The Type-C version features an integrated high-resolution 24-bit/96kHz DAC and hardware DSP, allowing users to switch between PEQ presets and customize a 5-band equalizer via the TANCHJIM app.

• Ergonomic Medical-Grade Shells: Molded from high-transparency, lightweight resin with a sleek, minimalist rabbit-inspired aesthetic and frosted stainless-steel accents for long-term listening comfort.
