Thanks for the message mapman...
I am very satisfied by my headphone K340 ,an hybrid, the only real one dating back 45 years ...But i am curious about any actual top headphone which may beat them on all acoustic factors , bass , holography , natural timbre , highs as honey and a balance with a speaker-like sound out of the head if the recording is good ... I never listen an headphone which can even touch them ......I trash all the 9 others in a bin because nevermind the design they sound unnatural, artificial and in the head ...
