Thank you for viewing! I am selling the Technics AZ100. This item is subject to strict restrictions by the manufacturer, including limitations on discounts and coupon usage at retailers. Similar to Panasonic's other home appliances like hair dryers and TVs, the selling price is predetermined. This model is Technics' latest and is a popular model with a No. 1 rating and performance among wireless earphones under 40,000 yen. It further pursues high sound quality, incorporating the "magnetic fluid driver" technology from the flagship wired model EAH-TZ700, specially adapted for completely wireless earphones. By bringing together high-quality sound technologies such as "spatial design" and "circuit design," it achieves excellent spatial reproduction across a wide frequency range, from ultra-low to high frequencies. Aiming to reproduce music that conveys the artist's intentions as they are, the completely wireless earphone EAH-AZ100 was created. Magnetic fluid is a magnetically charged liquid placed around the voice coil that drives the diaphragm, supporting the diaphragm. In addition, the edge supporting the diaphragm is made with a soft, ultra-thin edge structure to expand the diaphragm's amplitude range. Meanwhile, the diaphragm material is made of highly rigid aluminum, allowing for a wide range of reproduction from low to high frequencies without micro-deformation even with intense movement. These configurations and materials enable accurate diaphragm operation, excellent spatial reproduction, and ultra-low distortion, clear playback sound across a wide range from ultra-low to ultra-high frequencies. The noise-canceling performance is adjusted to maximize performance based on the surrounding environment and each individual's ear shape. Compared to the previous model EAH-AZ80, the noise-canceling performance achieves greater noise reduction, especially in removing noise from trains and airplanes, and human voices. Furthermore, the feeling of stuffiness and muffled sound that occurs in the ear during noise canceling has also been improved. It has top-class performance in all categories, including sound quality, noise cancellation, external sound capture, and customizability. Thank you.
