Exceptional headphone, one of the best closed headphones ever created with excellent noise isolation in both directions and a high sensitivity so that it can be driven well even straight from an iPhone or iPod headphone out (naturally it scales with teh quality of the source and better sources will improve the sound). Also, possibly the best looking headphones ever created (I know that matters to some).
Purchased new a couple of months ago, and in immaculate condition, from memory warranty is five years.
Price new is $1400US.
Selling for $1000 (under no pressure to sell, this price is firm).
Selling as I personally prefer the sound signature of my T5p (although amongst audiophiles the Ed8 is largely favoured over the T5p in fact), and additionally I have to fund a couple more purchases :)
