FOCAL LENSYS PRO - Closed Studio Headphones

FOCAL LENSYS PROFESSIONAL – Closed studio headphones

FOCAL LENSYS PROFESSIONAL headphones are designed for sound engineers, producers, and musicians who demand closed-back sound with maximum precision and isolation in any environment. Equipped with 40 mm aluminum-magnesium M-shaped transducers, they offer an ultra-linear response from 5 Hz to 22 kHz (± 3 dB), a sensitivity of 100 dB SPL/1 mW, and an impedance of 26 Ω, with a total harmonic distortion of less than 0.3% at 1 kHz/100 dB SPL to preserve every nuance of the signal. Their closed, circumaural construction guarantees up to 23 dBA of passive isolation, allowing absolute concentration during mixing and editing. The solid aluminum frame and microfiber-covered memory foam ear cushions provide ergonomics and comfort during long sessions, and come with two detachable cables (1.2m straight and 3m coiled), a 3.5mm–6.35mm jack adapter, and a hard carrying case.
