E2 EARSET

Thanks for choosing the Countryman E2 Earset microphone. We’re confident you’ll find
it the finest, most natural sounding, and most unobtrusive earset microphone available.

The E2 provides high-quality pickup and excellent isolation with an ultra-miniature
condenser element positioned near the ear and a directional pattern tuned to pick up
the natural sound of the wearer while rejecting ambient noise. The entire assembly
weighs less than one-tenth of an ounce and disappears against the skin or in the hair, so
performers can forget it’s there and audiences barely see it.

We use innovative engineering to pack this great a sound into such a tiny mic. For this
reason, getting the best results requires some simple techniques that might not be
immediately intuitive. This booklet will help you get the most out of your E2 Earset.

Handling the E2

While the E2 Earset is designed for durability,
moisture-resistance and flexibility, it is a high­precision instrument and we do suggest some basic
precautions to prevent damage or sonic degradation:

• Always use the E2 with its cap in place. The end

caps are critical to the sound quality and also
protect the capsule from makeup, moisture, and
debris.

• When a protective cap is not in place, avoid

touching the end of the capsule with fingers or
obstructing the opening with foreign substances.

• The earpiece, boom, and end cap may be cleaned

with alcohol wipes, spirit gum remover, or acetone.
Do not use water or chemicals on the capsule itself.

• Clean the caps separately.

Handling the E2 (cont.)

The E2’s earpiece and boom are constructed of an
exceptionally flexible material which can be easily
shaped to the wearer’s needs. To prevent damage to
your Earset:

• Avoid bending it over sharp angles (such as the
end of your ngernail) or around a tight radius (less

than 1/2” diameter).

• Avoid bending the booms within 1/2” of the

capsule or the earpiece within 1/2” of the
connector.

• Use the side of your nger or other rounded object.



Connecting E2 Snap-On Cables

The Earset cable is easy to remove and change,
allowing you to swap transmitter types, switch colors,
or replace damaged parts in the field. Exercise care in
connecting and disconnecting the cable connector.

• Always grasp the connectors near the outer ends

of the rubber sleeves and pull the connectors
straight apart. When connecting listen for a click.

• The connectors do not unscrew—line up the marks

on the connector overmold and pull straight out to
disconnect.

• Avoid grasping the connectors where the sleeves

overlap, as this can weaken the moisture-resistant
seal and deteriorate the integrity of the connection.

• Do not pull by the cable, boom, or springy part of

the Earset.

Custom Fitting the E2

Head-worn mics provide isolation by keeping the
element consistently near the mouth. The ideal
placement is with the tip of the element in front of
the ear, about 1/8” away from the face. Since every
performer’s face is different, we’ve made it easy to
custom fit the E2 Earset:

1. Curve the boom so that it will rest against your face
when worn.

6

2. Put the loop over the ear with the base behind the earlobe
and the capsule toward the mouth.

7

3. Tip the mic to point toward the mouth.
The mic should be barely visible,
resting about 1/8” from the face mid
cheek or completely hidden by the hair.

4. Always use the collar clip to reduce clothing and cable noise. Leave enough slack in the cable such that the user
can turn his/her head to both sides without tugging on the clip. Use the windscreen outdoors.

9

Using Collar Clips

The Earset comes with two collar clips: one black and
one white. These clips prevent movement in the cable
from dislodging the Earset and can reduce cable
noise. They are specifically designed to match the
diameter of your E2 cable.

Gently pull the cable down into the opening to attach
the clip. Gently pull the cable out to remove the clip.

We recommend always using a collar clip with the
E2. Use both attachment points as shown. We
recommend leaving the clip attached to the cable
when possible to minimize repetitive strain.

Back Port Cleaning Procedure

This procedure is rarely necessary, but it may help if frequency response and
directionality have deteriorated because the back ports on the element are
contaminated with dust or makeup.

Make sure your hands, the work area, the Earset’s boom and end cap are clean.
Take a 6” - 8” piece of clean painter’s or gaffer’s tape and form it into a circle,
sticky side out. Stick it down on the top of a table, near the edge. Do not use
tapes that may leave adhesive on the mic.

Remove the cable and end cap. Hold the Earset by its boom, about an inch from
the bare mic element. Lay the element down on the adhesive, with the earpiece
hanging off the edge of the table. Gently roll the mic a full 360° along the adhesive
to remove dust or debris. Replace the end cap and cable.
