To celebrate Audio-Technica's 50th Anniversary, A-T has introduced the Audio Technica ATHM50SLE Limited Edition Studio Monitor Headphones. Designed especially for professional monitoring and mixing, the ATHM50SLE studio headphones feature an efficient collapsible design for space-saving portability and storage. Circumaural ear pieces swivel 180 degrees for easy one-ear monitoring and luxuriously padded ear cushions create an outstanding seal for maximum isolation. These limited edition headphones also feature an adjustable headband that is generously padded for ultimate comfort during long mixing sessions. A straight cable at the left earpiece terminates to a gold-plated mini-plug with included screw-on 1/4-Inch adapter. Audio-Technica's sophisticated driver technology and superior components deliver exceptional power handling and very high SPL capabilities while maintaining clarity of sound throughout their extended range, with deep, accurate bass and outstanding high-frequency extension. The ATHM50SLE Limited Edition Studio Monitor Headphones feature proprietary large-aperture drivers with neodymium magnet systems for ultra-efficient signal transfer.
