The high

mechanical

design of the enclosed

Sennheiser

HD 224 headphone with

forms

the basis

of the HMD 224 headphone

combination.

The

directional

microphone

used

for

this purpose

is identical

to that used

in

the

HMD

414 -6

described previously and

naturally

displays the same advantages. The

combination of

headphone

and microphone

weighs

a total of

only 360 g. It is therefore

lightweight

and comfort-

able to

wear

and

is

absolutely

ideal for

studio use

and a

wide

range of commercial application.
