Take listening to your favorite sound source to new heights. All you need is the advanced and innovative Audio-Technica ATH-M50 pro audio headphones. Seen worn by Justin Bieber in the studio shots for his "Love Me" music video, this pro gear isn't just for professionals. Whether you're listening to voice, music, or effects over this Audio Technica model studio headphone, it delivers crystal-clear, precise tones with an uncannily accurate response. This makes the ATH-M50s suitable for everything from everyday use to professional DJ setups. These Audio-Technica ATH-M50 headphones also boast a collapsible design that allows for compact storage and easy portability. Take them from one recording location to another without losing significant space in your bag. This portable headphone set features highly sophisticated technologies to encourage a superior signal transfer. These technologies include fine-tuned proprietary 45-millimeter large-aperture drivers, a neodymium magnet system, and a CCAW (copper-clad aluminum wire) voice coil. Combined, they provide professional-level sound quality for even beginning audiophiles whether for practicing, performing, recording, mixing, or casual listening. A thick, coiled OFC litz wire cable then connects you to all this high-tech quality at the left earpiece. At its other end is a gold-plated, stereo 1/8-inch (3.5-millimeter) mini plug. The connector includes built-in strain relief technology. This is a series of ridges placed where the cord meets the connector. It permits the cord to be flexible without placing undue strain on that spot, which is the most vulnerable on a cable. The ATH-M50 headphone set also comes with a 1/4-inch screw-on adapter for more versatile compatibility, such as to plug into a home receiver. Signals pass through this cord and into the speakers with very little degradation or loss. Combined, these technologies allow the M50 line of pro audio headsets to offer high SPL capabilities without compromising sound quality. That covers the full range of sound, too, from low-frequency deep bass to high-frequency treble tones. The circumaural (over-the-ear) full ear cup design of these Audio-Technica studio monitoring and mixing headphones provides excellent noise isolation. It does this with a dynamic closed-back design and thick, comfortable ear-pads that together create a tight seal to insulate against outside sounds. At the same time, the earpieces swivel on two axes at 180 degrees, which makes it easy to monitor with only one ear when necessary. A luxuriously thick, padded, adjustable headband in black ensures your comfort at all times. These studio headphones are also incredibly lightweight, weighing only 10 ounces (284 grams) without the cord or connector attached. Combined, all of this lets you enjoy the finest audio quality for long sessions of playing or mixing. These professional Audio-Technica monitoring and mixing headphones have the ability to handle up to 1,600 mW of sound signals. That makes them powerful and robust enough to keep up with you and your audio needs every step of the way. They have a 38-ohm impedance and a 99 dB sensitivity. They have a minimum frequency response of 15 Hz and a maximum frequency response of 28 Khz. The unit comes with its own protective pouch. Whether you want to listen to the bass notes in rock music or the soft melodies in a classical piece, these Audio-Technica headphone accessories will let you do just that.
