The Stairway to Sound, Now Within Reach.

From design to acoustics, from craftsmanship to fit—every step evolves for a truer listening experience.

Unified Design Language, Synergistic Acoustics

From the DAC/amp to the in-ear headphones, both are centered on the "Gradient Musical Staircase" design. They blend precision metalwork with a gradient visual rhythm, creating an industrial-aesthetic loop from desktop to portable. More than just devices, this is a complete design ecosystem—keeping the listening experience consistently immersed in the same aesthetic context.

Reproduces a Precise Soundstage

Moving beyond traditional dynamic driver structures, it achieves more uniform diaphragm motion for accurate soundfield reproduction.Improved diffusion technology ensures equal sound pressure levels in both directions when the planar diaphragm vibrates.The bidirectional design enhances phase consistency, reduces phase cancellation, and delivers clearer sound.

13mm Planar Driver

Nanoscale Magnetron Sputtering Coating

Delivers an atomically uniform coating on the planar diaphragm,
ensuring extended high frequencies and transparent detail.

Micron-Level Etched Ring Copper Voice Coil

Precisely etched copper ring driver enhances transient response and midrange density.

TPU Flexible Surround

Effectively increases diaphragm stability, providing solid, full bass and smooth, natural vocals.

2×7 N52 High-Strength Balanced Magnetic Strips

High-Fidelity, High-Resolution, High-Speed Transient

A symmetrical magnetic circuit design lowers resonance frequency and delivers powerful, uniform driving force, achieving true high-fidelity, high-resolution, and high-speed transient performance.

TTT-E3
