Sony Walkman 128GB WM1 series Equipped with Android Compatible with cable DSDDSD Native playback PCM playback Equipped with DSEE Ultimate DSD

【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. Equipped with Android OS. Long-awaited streaming support. Noise countermeasures are also thoroughly implemented by strengthening the power supply, digital block power supply, and strengthening and stabilizing the grind. The internal design has been carefully designed to minimize sound quality reduction to prevent the negative effects of the digital block on the analog block. Aluminum is used on the back. By making it one-piece aluminum, it achieves even higher rigidity than the previous model. Adopts new gold solder and achieves ultimate sound quality by hand soldering. In addition, a 4-core Kimber cable is used for the headphone cable for internally balanced output. Blocks out external noise and transmits high-quality audio signals. FTCAP3 is used for all bypass capacitors of the audio block power supply. Further tuning of the internal structure of the capacitor was carried out. Utilizing the development know-how of home stationary audio equipment, it contributes to improved sound quality by improving vibration resistance. In low phase noise oscillators, the electrodes of the crystal pieces are formed by gold vapor deposition. Equipped with DSEE Ultimate/DSD Remastering Engine Using AI (artificial intelligence) technology that learns from a huge amount of music data, it analyzes the music scene in real time and optimally upscales it to high quality sound. Bit expansion and sampling frequency increased to a maximum of 192kHz/32bit equivalent. By using AI (artificial intelligence) technology, the type of song is automatically determined, and in addition to the high range, the reproduction of fine sounds is further improved. Upscaling technology for CD-equivalent lossless codecs (Flac 44.1kHz/48kHz) has evolved. Equipped with a "DSD remastering engine" that converts all input PCM sound sources into 11.2MHz equivalent DSD signals. Sony's unique algorithm converts the original data into a DSD signal without sacrificing the amount of information. Evolved from 5.6MHz of the previous model to 11.2MHz. Enhanced duration. Can be played continuously for up to 40 hours.
