"The Phonon 4000 headphones are priceless in my opinion as they are
very dynamic, loud and "bass-friendly" for dj use in clubs, while at
the same time they are very tight and precise in their sound
definition allowing producers to work on Music production while on the
road as a real pro monitoring référence tool "
