TWISTURA SIGMA Hybrid Earphones Dynamic Driver and BA Driver Aluminum Alloy OFC Silver Plated Cable Adapter Impedance Adapter Detachable Microphone

---------------------------------------------------------------------- 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ---------------------------------------------------------------------- [Small, high-performance dynamic driver unit] This is a small, high-performance dynamic driver unit that combines a sophisticated acoustic design with a 6mm LCP dome composite diaphragm. [LCP (Liquid Crystal Polymer) Dome Composite Diaphragm] The polymer structure of LCP (Liquid Crystal Polymer) achieves high-precision molecular alignment, suppresses resonance caused by the divided vibration of the diaphragm, and improves the sound transmission characteristics of the diaphragm. It achieves clear sound with suppressed distortion, and achieves smooth, natural sound with excellent response. [Customized "60040" BA driver, faithful and mellow sound] The "60040" BA driver, which is in charge of the mid-high range and is customized exclusively for SIGMA, is a BA driver that achieves high response and excellent conversion efficiency. By adopting this BA driver, it produces clear and powerful mid-high range sound, and by enriching the sound details, it realizes sound with excellent fidelity and resolution. [Professional Acoustic Tuning] In order to provide superior performance that can meet all needs, SIGMA has been meticulously tuned by an engineer with extensive tuning experience. The low end is tight and moderate, the high end is beautiful and natural, and the balanced full-range performance and wide sound field expression allow users to enjoy detailed and realistic sound in a variety of genres of music. [Sophisticated coaxial integrated chamber design] An integrated chamber is used to coaxially arrange the dynamic driver and BA driver units, suppressing noise and distortion caused by resonance. This cleverly designed chamber structure smooths the connection between the two units, achieving a unified sound without the feeling of frequency band separation due to crossover. [A fusion of traditional design and transparency] SIGMA uses a traditionally shaped shell with a hybrid design that combines aluminum alloy and transparent resin. The traditional and compact hybrid shell design provides an easy-fitting fit and a harmony between the exquisite texture of the metal housing and a fashionable design. [High-quality lossless transmission, OFC silver-plated cable] The cable uses OFC silver-plated wire, which reduces signal loss due to oxygen-free copper, has excellent conductivity, and the silver plating prevents deterioration of the wire, reducing signal distortion, achieving excellent signal transmission quality. By bringing out the pure sound that is SIGMA's original, it enriches the details of the sound and provides a clear and warm listening experience. [Wide range of options, high-quality Type-C adapter included] A Type-C adapter equipped with a high-quality DAC chip is standard equipment so that it can be used with a wide range of options. It supports sampling rates up to 32bit/384kHz, providing a high-purity listening experience for smartphone streaming service and gaming users. [30Ω impedance adapter included as standard] When connecting to a high-output device or a device with excellent driving performance, using an impedance plug reduces front-end noise and provides a more comfortable listening experience. *When using this plug, microphone input and remote control are disabled. SIGMA adopts a dual hybrid configuration with one dynamic driver and one BA driver. The low range uses a dynamic driver equipped with a 6mm LCP (liquid crystal polymer) dome composite diaphragm to achieve rich and tight low frequencies, while the mid-high range uses a customized "60040" BA driver to achieve excellent sound detail. This hybrid configuration achieves mutual cooperation by pursuing the target curve through delicate tuning and precise crossover control to cancel out the shortcomings of each unit. This allows SIGMA to achieve a comprehensive and balanced sound performance by combining the advantages of the dynamic driver and the BA driver.
