索尼六年后重启经典XM4耳机

事件：Six years ago Sony and Bose were in the middle of a noise-canceling battle, with each new model of headphones better than the last. In the fall of 2020, Sony released the WH-1000XM4 headphones to wide acclaim. They sat atop best headphones lists for years, thanks to their great sound, competitive ANC, and compact size, until they went out of stock. Now Sony has brought them back, with minor improvements, as the WH-1000XM4C.
