Audio-Technica M-Series ATH-M40x
The 40mm drivers and 15Hz-24kHz frequency response deliver a flat, accurate sound signature ideal for critical listening, while the closed-back design provides effective isolation. The robust build includes interchangeable coiled and straight cables for flexible setups, and the swiveling earcups are practical for one-ear monitoring during sessions. These headphones are best for audio engineers and musicians who need a durable, neutral-sounding monitor for tracking and mixing.
