Perfect condition, 1-month old HD590s for sale. Original box & manual. Around 150 hours on them, nice and burned in for you. Have to sell because I need closed 'phones for work so I won't bug my co-workers when I play at LOUD levels. They are 120 ohm (HD580/600 are 300 ohm) so they can be driven effectively w/out an amp. I've run them out of my Turtle Beach Santa Cruz soundcard w/ excellent results. The HD590 is one of the most comfortable headphones made today, with a single cord attached to the left-side. There's also a worthwhile upgrade path with the Stefan AudioArt Equinox cable (not included) if you suffer from the upgrade itch in the future.
Asking $140 shipped ($249 at Headroom, $175 at Meier, plus S&H).
