The SHD60 Headphones are made for Hi-fi, Live and Studio applications and for when accurate reproduction of your source material is your number one priority. They feature an Accu-tuned, semi-open Acoustic Chamber design that gives you a wide dynamic range and superior low end reproduction. The SHD60's frequency response of 10Hz to 30000Hz attests to that. With a rated Impedence of 32 Ohms @ 1kHz and power handling of 300mW, distortion is kept to an absolute minimum. The self adjusting headband on the SHD60 is made for maximum comfort for long listening sessions and its single side cable connection ensures that tangles in its 2.5 metre cable are kept to a minimum. The SHD60's gold plated 1/4 Jack connector can be removed to reduce it to a 3.5mm Jack size - allowing you to use these headphones with your keyboard, mixer, computer, phone, guitar amp and more. It also comes with a handy carry pouch.
