The white HD-681EVO headphones from Superlux combine premium-quality audio components with a slender, ergonomic design to offer accurate music reproduction with full-range frequency response (10 Hz to 30 kHz) and smooth high frequencies, in a lightweight and comfortable package. Ideal for long, fatigue-free listening sessions, they are intended for use by musicians and audio professionals in monitoring applications, including recording live instruments and vocals, mixing, and more.
The HD-681EVO features around-the-ear earcups which provide sound isolation from outside noise and help eliminate "headphone bleed" when recording in the studio. The semi-open design delivers a natural sound while still offering deep bass response and minimal sound leakage. Two 50mm neodymium drivers provide a rich, balanced sound with high resolution, wide dynamic range, and excellent stereo imaging.
The headphones are equipped with a self-adjusting headband and thick around-ear cushions, providing the listener with a great fit. The HD-681EVO comes with a protective storage pouch, a gold-plated 1/4" adapter, and two detachable straight cables (3.28' and 9.84' in length).
