The HD-681 headphones from Superlux combine premium-quality audio components with an ergonomic design to offer accurate and detailed sound 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-681 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-681 comes with a gold-plated 1/4" adapter.
