Miniature Unidirectional Earset Microphone

Please let us know the complete brand and model information of your transmitter. Many connectors have multiple wiring options depending on which transmitter will be connected.

Please specify your transmitter in the notes section of the shopping cart or in the comments section of your order.

Your order could be delayed if we need to contact you to find out what transmitter your have.

Pure Sound, Nearly Invisible
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. We 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 gain before feedback.

New 1.5mm Cable
Our new extremely-rugged 1.5mm cable will replace the 1mm and 2mm cable options for the E2 Earset. The 1.5mm cable uses a braided Aramid strength member to achieve nearly 50 lbs of tensile strength. With conductors made of engineered alloys, the cable also features outstanding flex resistance and suppleness. This cable is the perfect balance of flexibility, low-visibility, and ruggedness, and should be the ideal option for any E2 Earset application including theater and broadcast.
  • Detachable cables
    Unlike earsets that are hard-wired from mic to connector, our cables quickly and securely snap into the E2 earset.
  • Nearly Invisible
    With a diameter of only 0.1" (2.5mm) - the size of a No. 2 pencil lead - the mic capsule virtually disappears when worn.
  • True colors
    Our colors are precision-matched to theatre makeup shades to blend with a wide range of skin tones and clothing.
  • Tuned response
    Precise frequency response tuning makes for a natural, intelligible sound.
