APPLICATIONS
The DT 770 PRO is a closed, dynamic headphone for
professional use as a monitoring headphone in studios.
Its design has been tailored for use in a studio.
The single-sided cable makes it easier to handle the
headphones when they have to be constantly put on and
taken off. The robust spring steel construction gives the
headphones a secure fit and the mechanical reliability
needed for daily use.
Soft, adjustable ear cups and a single-sided cable
contribute to a high level of long-term comfort.
The connecting cable is fitted with a gold-plated mini
stereo jack plug (3.5 mm) with a 1/4" adapter (6.35 mm) and
can therefore be connected to all common headphone
outputs.
With its impulse behaviour, the DT 770 PRO comes close
to electrostatic headphones and delivers a natural and
balanced sound. Even the deepest bass is reproduced
with clarity and punch. High frequencies are converted
into an analytical, clear and differentiated sound that
does not produce screaming or shrieking even with
powerful treble sounds.
