TWISTURA / SIGMA with Mic 1DD+1BA hybrid earphones

Variations

The SIGMA uses a dual hybrid design combining a 6 mm LCP dynamic driver and a custom BA ‘60040’. Precise tuning and crossover control based on target curves brings out the best in each driver, resulting in a rich, balanced sound.

■ Dynamic driver with LCP diaphragm
Compact but high-performance newly designed driver with LCP characteristics suppresses resonance and ensures excellent acoustic transparency. The driver delivers smooth, natural low frequencies with excellent response.

■Faithful and sensitive mid- and high-frequency reproduction
BA drivers tuned specifically for SIGMA provide high conversion efficiency and responsiveness, expressing transparent mid-high frequencies and fine detail.

■ Acoustic tuning by professionals
Tuned by experienced engineers to deliver both tight low frequencies and natural high frequencies. The wide soundstage and high reproducibility provide a realistic musical experience for a variety of genres.

■ Coaxial integrated chamber design
The unique structure of the coaxial arrangement of the drivers suppresses resonance and bandwidth fragmentation, resulting in a natural sound with a sense of unity.

Fusion of classic design and modern materials
The shell, which combines aluminium alloy and transparent resin, offers both a comfortable fit and an elaborate, sophisticated appearance.

■High-purity OFC silver-plated cable
High-conductivity OFC silver-plated cables are used to minimise signal loss. Delivers clear, warm sound that is faithful to the original sound.

High-quality Type-C DAC adaptor included
An adaptor with a DAC supporting up to 32bit/384kHz is included as standard. Enables high-quality sound reproduction even with smartphones and games.

■30 Ω impedance adaptor also included.
Reduces noise when connecting to high drive power devices, enabling more stable listening. *Microphone function disabled when used.
