E6 Flex Omni Datasheet
The E6 Flex Omnidirectional Earset combines the best of the classic E6 Omni
Earset with the best of the omni E6i. The slim, springy ear section grips securely
like a classic E6, while the flexible front boom takes abuse like the E6i and allows
precise placement and easy reshaping. As part of the Countryman E6 line, the
E6 Flex features swapable reinforced cables, versatile skin tone options, extreme
water resistance, rugged construction, and uncompromising sound. It weighs less
than one-tenth ounce, virtually disappears against the skin, and custom fits so
performers forget they’re even wearing a mic. It’s what makes an E6 an E6: the
smallest, highest-performance earset in the world.
The Best of Both Worlds
Exceptional Sound
The fit of the classic E6 meets the
flexibility of the E6i. Countryman earsets
are the smallest, lightest, and least visible
head-worn microphones available.
The slim earpad doesn’t interfere with
hairstyles, eyeglasses, wardrobe,
headphones, or in-ear monitors. The front
boom of the E6 Flex is slightly firmer than
our E6i, so it’s easily shaped right on the
performer’s face and smooths out for a
professional look.
Frequency response is better than 20 Hz
to 20 kHz ± 3 dB, with >100 dB dynamic
range. Easy adjustment keeps the mic in
the perfect position for maximum isolation.
Countryman omnidirectional earsets
increase headroom an average of 12 dB
compared to an omnidirectional lavalier.
Change the look, change the sound, or
change the transmitter. Protective caps
swap in seconds, adjusting the frequency
response between flat, bright, or very
bright to improve speech intelligibility.
The E6 Flex comes in three sensitivities
for different speaking and singing styles,
with up to 140 dB SPL capability. Switch
between low-profile 1mm and Duramax
2mm cable, configured for almost any
wireless transmitter and available in four
Rugged and Reliable
Made of durable stainless steel, the E6
Flex stands up to daily handling, makeup,
and sweat. The microphone element is
virtually waterproof when used with the
supplied protective caps.
Supplied with cable, carrying case, black and white
cable clips, wind screen and 3 protective caps.

E6 Flex Omnidirectional: Frequently Asked Questions
How do I wear an E6 microphone?
1. Tighten the ear loop.
2. Slide your fingers to
curve the boom.
3. Spring the connector
away from the boom.
4. Put the loop over the ear with the base behind
the earlobe. The boom can touch the cheek.
5. Put the mic near the
corner of the mouth.
How do I choose the right E6 for my application?
• The E6 Flex offers a versatile blend of the E6 and the E6i. With a springy, thin earpiece and a flexible
boom, the E6 Flex is faster to fit a new face than any other earset microphone available—all without
compromising true invisibility and world class sound. The E6 Flex is marked with an orange band.
• The classic E6 is a good choice when one person will wear the microphone. Because the boom
is stiffer, once it is adjusted to fit the user’s face, it can be stored away, unpacked, and quickly
worn with a minimum of fuss.
• The E6i is soft and highly-flexible with a larger silicone rubber ear piece. When multiple users share
a mic, the E6i is a great choice. The soft boom is fantastically durable and the extreme flexibility
makes changing users a breeze.
When should I choose a directional earset rather than an omni?
The omni earset rejects unwanted sound and feedback better than a lavalier almost any way you wear it, so it’s
very user-friendly for new and experienced users alike. For situations where there are loud monitors, extreme
feedback or environmental noise, choose the Countryman Directional Earset (marked with a green band).
How do I choose the right color for my skin tone?
In most cases the boom of the E6 will be against the performer’s skin. Tan is the most popular color choice,
because it works perfectly for average Caucasian skin tones as well as olive complexions. Light beige works
well in theatrical applications due to its slightly pink undertone, which is also appropriate for extremely fair
skin. Cocoa is the ideal choice for African American skin tones ranging from very light to chocolate, and
black is appropriate for extremely dark skin or for situations where you want the mic to be visible. When in
doubt, a darker option tends to blend better and draws less attention.
Which E6 sensitivity should I choose?
Making a microphone more sensitive to catch soft sounds means it will overload sooner for loud sounds.
Because sound pressure levels vary between individuals and applications, we provide three sensitivities for
the E6 Flex:
• The highest gain (W5, no colored band) is for general speaking, such as presentations or sermons
• The medium gain (W6, blue band) is for vocals and loud speaking, such as in theater
• The most powerful vocals require the least gain mic (W7, purple band) with the highest overload level
Which cap should I use?
The E6 should always be used with a protective cap in place to keep sweat, makeup and other
foreign material out of the microphone. The three omni caps each have a different high frequency
response characteristic that controls the amount of “crispness” or “sibilance” (response at 15 kHz).
The omni ships with the +4 dB protective cap fitted to the mic. We have found that this meets the
needs of the majority of users, slightly boosting the presence in your sound while leaving the lower
frequencies unchanged. If you experience problems with high-frequency feedback, you should
switch to the 0 dB cap.
