Focal UTOPIA

My Personal Utopia's.  Used ten times.  Love them but need the money to buy baby stuff (who knew at 60 :). Anyway, they have been on a headphone stand and have never left my office.   New Iphone shows everything but there is no wear on the headphones since been on my head less then 20 hours.   Love them though!
Utopia are THE reference high-fidelity headphones manufactured
by Focal. They are the result of 35 years of innovation, development 
and manufacturing of high-end speaker drivers and loudspeakers. Equipped 
with exclusive technology, they offer striking realism, neutrality, 
dynamics and clarity, for sound with unrivaled purity. Utopia are 
unique they are the world’s first audiophile headphones to be 
equipped with totally open-backed full-range speaker drivers with pure 
Beryllium ’M’-shaped domes. They meet all the requirements 
expected of high-end headphones due to their sophisticated and elegant 
design and to purposeful materiality, such as the carbon fiber yoke and 
true lambskin leather ear cushions. The acoustic quality of this 
exclusive solution allowed Focal to avoid the use of any crossover or 
passive filtering process to achieve a frequency response from 5Hz to 
50kHz!  
The listening experience is outstanding in terms of realism, 
natural sound reproduction, dynamics and clarity. When listening to 
them, the headphones virtually disappear and the audio signal is revealed with a level of precision never achieved until Utopia. Utopia phones are simply amazing

“The 
Elear and Utopia are simply extraordinary. The sense of dynamism,tonal 
balance, and smooth clarity of both are, to put it mildly,disorientingly disruptive to my sense of where headphones are at today and in what wayand by how much these are better.”
