Welcome to The Cool Life! I am a seller in Japan. I ship authentic products from Japan. Please enjoy shopping with peace of mind! You will find great products! 【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. World's highest class noise canceling (*) Integrated processor V2 and high quality noise canceling processor QN2e enable high level noise canceling processing and sound quality signal processing. In addition, Multi-Noise Sensor Technology is equipped with dual feedback microphones, feedforward microphones, and three noise-cancelling microphones in each ear, achieving overwhelming noise-cancelling performance. This enables an additional 20% noise reduction compared to the WF-1000XM4, allowing you to enjoy highly reproducible sound quality in unprecedented silence. * In the left and right independent wireless noise canceling headphone market. As of April 10, 2023, researched by Sony, in accordance with Japan Electronics and Information Technology Industries Association (JEITA) standards. Sony's uniquely developed 8.4mm new driver unit Dynamic Driver With a diaphragm structure that combines different materials for the dome and edge parts, the soft edges reproduce sinking bass frequencies, while the lightweight and highly rigid dome reproduces extended treble frequencies. High-quality processing from signal processing to playback suppresses distortion and achieves overwhelmingly high sound quality with high reproducibility. High fitability and minimal design achieved through smaller size and lighter weight Achieved smaller size through Sony's uniquely developed thin new driver unit and SiP main board. The weight of the attached part was 7.3g in the previous model WF-1000XM4, but it has been reduced to 5.9g in the WF-1000XM5. By reducing the volume of the earphone body by approximately 25% compared to previous models, interference with the ear is reduced and comfortable wearability is achieved. The inside of the earphone has an ergonomic surface design that supports the earphone itself on the surface that comes into contact with the ear, and has a curved shape that fits inside the ear. Furthermore, due to the shape design with reduced height, the part that protrudes from the ear is small, achieving excellent wearing stability. The microphone part uses a...
