Sony MDR-1A Premium Hi-Res Stereo Headphones (Silver)

The silver Sony MDR-1A Premium Hi-Res Stereo Headphones use 40mm Aluminum coated Liquid Crystal Polymer (ALCP) dynamic drivers to deliver a frequency response that Sony indicates extends from 3 to 100,000 Hz, making them suitable for reproducing the information found in high-resolution audio at higher sample rates. Additional advancements include the use of 4-conductor cable for better signal separation, ergonomic earpads for long-term comfort, and the option of adding cables engineered by Kimber Kable.
