Technics today introduced two noise-cancelling wireless earbuds that improve on the sound quality and comfort of its previous designs. The flagship EAH-AZ80 ($300) and EAH-AZ60M2 ($250) earbuds feature Technics’ proprietary Dual Hybrid Noise Cancelling Technology, improved call quality, and the ability to connect with three source devices simultaneously in addition to a new ergonomic shape designed to ensure comfort, even when worn all day. The main difference between the two models is the use of a new 0.4-inch (10mm), free-edge aluminium diaphragm in the EAH-AZ80 .
