The veteran Berliner German techno DJ and music producer Mijk van Dijk (www.microglobe.de) (who started his career in 1990 in Berlin) shares his thoughts on the 4400: 

"The Phonon 4000 are my favourite compact headphones and a perfect solution for touring DJs.

They are very comfortable, super foldable and fit in the tightest record bag pockets but yet have a very accurate bass response and an honest overall sound. 

Ideal for producing tracks and ideas on the road, listen to the latest promos and of course for use in the DJ booth."
