The HD 420 SL is a Higti-qualty dynamic head¬
phone built according to the "positively open"
design. The cobalt samarium magnet systems,
extremely small in relation to diaphragm, are typical
of 'positively open" headphones.
So the diaphragm remains hardly covered towards
the outside thus allowing the ear to hear through
without interference.
Besides its excellent sound qualities the HD 420 SL
offers a high weanng comfort due its light weight
and soft ear cushions.
