Pure sound-every note! Drawing inspiration from a legacy of personal audio reproduction, Sony engineers have developed the perfect balance of Premium style and hi-resolution audio performance. Introducing the MDR-1A Stereo Headphone featuring thoughtful design, lush long-term comfort, and ultra-responsive Hi-Res audio response for a sound experience bar-none.	Prepare for exceptional sound Lightweight and responsive, aluminum-coated Liquid Crystal Polymer driver units possess the necessary rigidity and internal loss to deliver linear, wideband frequency response ranging from sub-harmonic lows (3 Hz) to ultra-sonic highs (up to 100 kHz) for balanced and natural sound reproduction.	High-conductivity Silver-coated oxygen-free copper (OFC) cable ensures minimal signal transmission degradation for pure audio response at the driver. A unique 4-wire architecture further enhances the audio experience, with a separate ground and signal connection to each driver for enhanced separation, expanded sound and tight bass.	Comfortable fit, powerful sound Pressure-relieving urethane cushions wrap entirely around your ears for a comfortable acoustic seal and powerful bass response, while precise component machining, with the added placement of silicon rings around every moving axis, realizes smooth and silent earcup movement. In the end, you can expect an immersive listening experience.
