Proprietary 45mm drivers and a dedicated amplifier deliver the same studio-reference sound as the wired ATH-M50x, while a 50-hour battery and 10-minute quick-charge give 3 hours. Multipoint Bluetooth pairs two devices simultaneously, and beamforming mics with noise suppression ensure clear calls; EQ adjustments are customizable in the app and saved directly to the headphones. Best for home-studio producers and audiophiles seeking the M50x’s flat response in wireless form for critical listening, not for commuting due to weak passive isolation.
