The E2 Earset redefines pure sound in a virtually invisible package that is easier to use than even a lavalier or podium microphone. Like the classic E6 Earset, the E2 rests over the ear, but has a much shorter boom. Its uni-directional element provides nearly the isolation of an E6 Omni at the mouth, but with significantly less visibility. With an equalizing circuit built into the audio connector, the frequency response is tuned so you can experience full-bodied bass and precise highs that are indiscernible from an E6 Omni at the mouth. The element, boom, and new sub-miniature connector are all easily hidden on the user’s face; the position near the ear eliminates breath pops and makes fitting easy and quick. This results in the smallest and most discreet professional-quality microphone available.

Excellent Isolation

In all kinds of acoustic spaces, the E2 achieves nearly the isolation (gain-beforefeedback) of an E6 Omni positioned at the user’s mouth. We tested the two mics against each other in several large and small venues and confirmed that in all cases the E2 gain-before-feedback was within 3 dB of the E6 at the mouth. There are two aspects of the E2 design that allow this to be possible so far away from the mouth: strong off-axis rejection and precisely-tuned frequency response. The off-axis rejection, as shown to the right as the difference between the solid and dashed blue curves, is strong for all frequencies in the audio band—not just 1kHz as with many competitive directional mics—so the feedback-rejection is equally effective in smaller or larger venues. For on-axis interferences, the frequency response tuning in the connector of the E2 allows us to fully capitalize on the proximity boosting effect of the mic to achieve even stronger isolation in the voice band. Comparing the on-axis frequency responses at 5 in. (solid blue) and 24 in. (dashed black) shows that sources even a couple of feet away from the user’s head will be strongly attenuated compared to the desired sound. Countryman tuned the frequency response of the E2 to be as flat as possible in use by taking into account the frequency-shaping properties of the head, and the acoustics of the mic itself. This results in full sound, and high gainbefore- feedback.

New Sub-Miniature Connector

Like the connector we use for the industry-standard E6, Countryman designed the connector for the E2 to be tougher and more water resistant than anything else avaiable. And smaller: the connector is smaller than the miniature E6 connector and features a flexible plastic overmold to create a positive seal against moisture. The plastic is matched in color to the protective cap on the mic, the boom, and the cable, ensuring that every component of the E2 remains hidden against the user’s skin.

How do I choose the right color?

Choose your E2 color based on whether it will rest against the skin or hide entirely in a sideburn. Either way, the E2 is so small that it will virtually disappear on the user’s face, even at a very short distance. For 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 E2 sensitivity should I choose?

Making a mic more sensitive to catch soft sounds means it will overload sooner for loud sounds. Because
sound pressure levels vary between individuals and applications, two sensitivities are available for the E2:

• The standard gain (5) is for almost all applications, including vocals and speaking.
• The lower gain (6) is for powerful vocals requiring the highest overload.

• Frequency Response : 20 Hz to 20 kHz
• Operating Current : 500 μA
• Operating Voltage : 1 to 2 Volts
• Weight : .07 oz (2 grams)
• The E2 Earset is available in two sensitivities:
  • Model E2W5 for general speaking
    • Sensitivity: 3.0 mV/Pascal
    • Equivalent Acoustic Noise: 34 dBA SPL
    • Overload Sound Level: 130 dB SPL
  • Model E2W6 for loud speaking and vocals
    • Sensitivity: 1.0 mV/Pascal
    • Equivalent Acoustic Noise: 39 dBA SPL
    • Overload Sound Level: 140 dB SPL
