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.
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.
Advanced Ruggedness: From cable
to connector to capsule, the H7 is our
strongest, most water-resistant, and most
resilient directional microphone yet.
Supplied with a 5’ H7 Snap-On Cable, carrying case, small and
large windscreens, and black and white cable clips.
