The ATH-D40fs stereo headphones from Audio-Technica provide pro-quality audio in a lightweight and comfortable design. The headphones feature 40mm neodymium drivers with copper-clad aluminum wire voice coils to produce a bass-enhanced frequency response that's ideal for mixing and monitoring low frequency sound sources. High-quality components give the headphones very high SPL capabilities.
The closed-back design and around-ear cushions provide a snug and comfortable fit that also blocks out unwanted environmental noise. The earcups also have a swivel mechanism for convenient single-ear monitoring. The padded, adjustable headband provides a secure fit that will keep you listening for hours. The single-sided OFC cable has built-in strain relief and is 11' long to provide plenty of slack. The standard 1/4" stereo plug lets you connect to virtually any professional audio device. These headphones are also field-serviceable, letting you easily replace the drivers, cable, and ear cushions when needed.
