H7 HEADSET

MICROPHONE

Decades of headset microphone design come together in the H7 Headset, combining
an exceptionally controlled directional pattern and wide dynamic range with user
comfort and durability.

Precision Focused Sound: Full frequency
response directed right where you need it,
the precision cardioid pattern of the H7 shuts
out feedback and surrounding noise.

Nearly Invisible: The ultra-slim side­address capsule comes in four color
tones to virtually disappear against skin.

Advanced Ruggedness: From cable
to connector to capsule, the H7 is our
strongest, most water-resistant, and most
resilient directional microphone yet.

Light and Comfortable: At less than 7
grams (.25 oz) the headframe adjusts to
fit different head sizes and the mic boom
slides to get the perfect fit.

Supplied with a 5’ H7 Snap-On Cable, carrying case, small and

large windscreens, and black and white cable clips.

H7 Headset: Features and Use

Advanced Water-Resistant
Connector: The unique

slim connector detaches
from the microphone and
provides more than 5 ATM
of ingress protection.

Extended Adjustability:

Both earloops slide in and
out to achieve a comfortable
and secure fit on small or
large heads.

Extra-Rugged Detachable Cable:
With other microphones, a worn
cable means you need to purchase
a new microphone. An H7 Snap-On
Cable attaches in seconds to adapt
the headset for virtually any wireless
system or powered interface.

Miniature Capsule: Ultra
slim side-address capsule
sheds sweat and moisture
while maintaining a low
profile.

Robust Construction:

Stainless steel tubing
and wire provide maximal
durability in a sleek design.
Engineered paints and cable
jackets ensure years of
performance on the road.

The 1.2 mm diameter
cable uses Aramid strength
members and engineered
alloys for extreme tensile and
flex strength.

Tailored Pattern: Carefully
crafted cardioid pattern
provides for easy placement
with solid rejection of
unwanted sound.

Precise Positioning:

The boom slides
independently of the
earloops to place the
mic right at the mouth
and flips for left or right
side placement.

Full-Range Directionality: Many directional microphones are
not very directional at low and high frequencies, resulting in
off-axis coloration, more ambient noise, and opportunities for
feedback. The H7 Headset has an extremely controlled polar
pattern across frequencies for natural sound and consistent
performance in any environment.

Versatile Colors: Countryman microphone colors are based
on popular theatre makeup shades designed to blend against
the skin. Tan works very well for Caucasian skin tones as well

as olive complexions. Light beige works well for light and pink
tones. Cocoa is ideal for light brown to chocolate tones. Choose
black for deep brown skin, or on other skin tones when you
want the mic to be visible. When in doubt, choose the darker
option. A mic that’s too light can resemble a scar or blemish,
while a darker mic reads as a shadow and draws less attention.
