Hybrid Drivers for Immersive Audio

The SIGMA is equipped with a 6mm LCP (Liquid Crystal Polymer) composite diaphragm dynamic driver for deep, rich bass, and a custom 60040 balanced armature driver to handle mid and high frequencies with precision. This hybrid dual-driver architecture offers a seamless blend of dynamic and balanced armature performance, ensuring a well-rounded and detailed sound signature with all the intricate details of your favorite tracks.

High-Performance LCP Dynamic Driver

The newly designed 6mm dynamic driver features an LCP composite diaphragm. The LCP's orderly molecular structure ensures excellent acoustic transmission, minimizing resonance and distortion while delivering smooth, natural tones. The result? Clearer, more precise audio with enhanced frequency response for a truly high-fidelity listening experience.

Custom 60040 Balanced Armature Driver

Specially designed for SIGMA, the 60040 balanced armature excels in delivering fast, accurate, and detailed mid and high frequencies. Its low distortion and smooth frequency response ensure a natural and vibrant sound, revealing nuances and textures in your music that are often overlooked.

Tuned for Audio Excellence

The artful acoustic tuning of the SIGMA delivers a balanced sound signature that’s both smooth and versatile. High frequencies are bright and natural, while the low frequencies are impactful yet controlled. The result is a transparent, wide soundstage with rich details, making SIGMA ideal for a variety of music genres.

Sophisticated Coaxial Acoustic Chamber

The SIGMA features an all-coaxial integrated acoustic chamber for reduced internal reflections and minimized distortion. Every component, from the sound tube to the drivers, is meticulously calculated and engineered for perfect synergy. This ensures a seamless blend of dynamic and balanced armature drivers, creating a cohesive and natural listening experience.

Innovative Design: Aluminum Alloy & Transparent Resin

Blending aluminum alloy with transparent resin, SIGMA’s design showcases its sophisticated internal acoustic components. The minimalist yet futuristic aesthetic reflects both elegance and technological prowess. Compact and lightweight, it’s as beautiful as it is functional.

High-Purity Silver-Plated Copper Cable

SIGMA comes equipped with a high-purity silver-plated oxygen-free copper cable, which ensures optimal conductivity and minimizes signal loss. This combination enhances sound clarity and detail, bringing your music to life with richer textures and greater resolution.

High-Performance DAC Adapter for Studio-Grade Sound

Included with SIGMA is a Type-C to 3.5mm DAC adapter, featuring a DCA decoding chip that supports up to 32-bit/384kHz sampling rates. This plug-and-play adapter delivers high-fidelity audio reproduction, bringing you closer to a live performance experience.

Impedance Adapter for Enhanced Listening

To further refine your audio experience, SIGMA includes a 30Ω impedance adapter. This accessory reduces noise from your audio source, ensuring a cleaner and more immersive listening session.

TWISTURA SIGMA - Hybrid headphones for vocal genres!

The headphones have a semi-open design, due to which the stage feels wide and spacious.
The image of the performer is quite large, located in the proscenium area.

The headphones have a smooth, neutral sound with a bias towards female vocals and emphasizing the beauty of acoustic instruments.
The overall presentation has warm tones, comfortable.

The vocals are very pleasant, softened, feel alive.
The backing vocals are well expressed, do not get lost in a bunch of instruments.
Female voices are transmitted very melodically, affectionately and melodiously, bring emotions!
The sound of acoustic instruments is rich, viscous, thick.
Low frequencies are present here in a monitor quantity.
The bass is fast enough, with good control, because the LCP diaphragm has high rigidity, and the small size of 6 mm provides that very monitor bass.
The headphones show signs of life at the bottom from 20 Hz and confidently wake up at 25 Hz.
However, you should not expect an abundance of low frequencies from the 6 mm driver, as I said, the headphone settings are quite smooth, the same applies to the low-frequency segment.
The midrange sounds moderately fat, quite full-fledged, but it is better not to feed them anything heavier than metallics, although things like Nightwish sound very interesting!
The high-frequency range in the upper octave is lowered, so you should not look for super details, these headphones are not for analytics, but for immersion and soulful perception.

Despite the rather budget segment, TWISTURA SIGMA create a very pleasant impression.
They are charming and you want to listen to them exactly what they are especially strong in, namely vocals, jazz and instrumentals, perhaps not too heavy rock and electronics.
