EarSpy - How does it work ?
In technical terms, the EarSpy micro earpiece is a wireless
receiver which transforms audio signals through electromagnetic induction.
The device can be used in exactly the same way as any other hands-free Bluetooth®
set, in conjunction with your cell phone, MP3 player or two-way radio. All
you have to do is “pair” the EarSpy Control Board to your cell phone in
order to make or receive covert calls. The wireless, undetectable earpiece
receives the signal from the phone through a transmitter.

The Bluetooth® compliant EarSpy
micro earpiece kit consists of:
- 3 Earpieces
– 2 x NANO (7mm x 5mm) earpieces and 1 x Normal (9mm x 7mm) (larger)
earpiece. Note: Earpieces require no battery or power source. The hi-tech
micro EarSpy earpieces use micro-pulse technology that emit signals
through electromagnetic induction.
- Neck
Loop which acts as an induction transmitter that sends signals to the
earpieces. The neck loop cable is covered with smooth cloth and can
easily and comfortably concealed under the user’s clothing
- EarSpy
Control Panel. The Control Panel is a pocket-sized PCB circuit board
to which the following devices are connected:
-
Microphone
-
Neck loop (transmitter)
-
Stereo jack for Bluetooth® enabled
MP3 player or radio
-
Battery clip to connect 9V battery
power source
-
Beeper button
-
Bluetooth cell phone connection
- Ultra
sensitive microphone
- Beeper
button
- Power
source: 9V rechargeable battery with recharger device*
* The rechargeable 9V battery pack (including charger and battery) is
an optional extra that can be purchased with the kit and does not come
standard with the EarSpy earpiece kit.

Method of Operation:
The user
conceals the neck loop (transmitter cord) under their clothes, conceals
the EarSpy Control Board in their pocket, inserts the EarSpy micro earpieces
in their ears, and before entering the room for that important exam or crucial
business meeting or court date, makes a call to their partner, or turns
on their MP3 player (if they have recorded notes). The EarSpy microphone
is ultra sensitive and can pick up even the softest whisper. The person
on the other end of the user’s cell phone will hear every word, even if
it is whispered. The beeper button can also be used to transmit simple yes
or no responses, which is especially useful in situations where the user
cannot speak out loud. The system is powered by a 9V battery.

How it works
The neck loop is attached to the EarSpy
Control Board, and acts as a transmitter. The neck loop sends signals
to the earpiece and the earpiece converts these signals into electromagnetic
vibrations which the ear drum picks up as sound.

EarSpy earpieces
|
| |
|
| |
The EarSpy kit comes standard with 3
skin-colored micro-sized earpieces:
- 2 x NANO earpieces (7mm x 5mm)
- 1 x Normal earpiece (9mm x 7mm)
These micro earpieces are designed to fit inside the ear canal (like putting
a tiny wad of cotton wool inside your ear). This conceals the earpiece completely
from any outside detection, and also positions it close to the ear drum
to emit sound vibrations. Because the micro earpieces work on a vibration
technology, it means that they cannot be overheard by anyone, and cannot
be damaged by ear wax as with so many other ear products. The EarSpy micro
earpieces come with a LIFETIME WARRANTY**
**The LIFETIME
WARRANTY includes the instant replacement of defective parts with a new
kit. The warranty ONLY covers inherent product failure due to manufacturer’s
defect. Any other cause of damages such contact with liquids or other corrosive
substances or foreign matter, wear and tear or abusive treatment, will NOT
be covered by the warranty.

EarSpy Control Board
|
| |
The Control Board includes volume adjustment
buttons and settings to allow call answer and end call, as well as voice
dialing and last-number dialing capabilities. It also includes a sync button
to activate the Bluetooth® capability in tandem with a cell phone. |

Neck loop
|
| |
 |
|
The transmitter (neck loop) is designed
to hang around the user’s neck, concealed under their clothing. The
neck loop is a thin and highly flexible cable designed for comfort. The
cable is covered by smooth cloth so that it does not irritate the skin and
will not cause skin allergies or other discomfort. (The cable has been laboratory
tested and approved to ensure that it is allergy free and safe to use).
TIP: For an even better fit and instant wear, the cable can be permanently
sewn onto the inside of a garment like a T-Shirt, or blouse. |

Microphone
|
| |
The ultra sensitive microphone is capable
of recording a whisper from a few meters away in a silent room. This EXTRA
sensitive microphone includes Smart Voice zoom/focus technology which enables
it to scan sound in the area selectively, ignoring background sound and
noises, for example, in a room full of people. The microphone is also concealed
under clothing. |

Beeper button
|
|
|
| |
 |
|
The beeper is very useful in situations
where it is not possible to talk. When pressed it sends a virtual tone over
the phone and yes/no responses can be made in this manner. The beeper can
also be used to send Morse code. |

Bluetooth®
|
| |
The EarSpy Control Board
is Bluetooth® v2.0 class 2 compatible. This communicates with all cell phones,
MP3 players, two-way radios or other similar devices with Bluetooth® capabilities.
Class 2 Bluetooth devices are rated at up to 10 meters in direct visibility
range. A2DP, Headset, Hands Free, AVRCP and SPP profiles are supported.
This means that you can keep your cell phone in your bag or jacket which
can be hung on the classroom coat rack meters away! That way there will
be absolutely NO PROOF that you are conducting secret communications with
an outside party. Simply begin the call by using the “last call” redial
button on the EarSpy Control Panel in your pocket. |

|
| |
|
| |
Power Source
|
| |
The EarSpy Control Board used a 9V battery.
Long life / heavy duty alkaline batteries, lithium batteries, rechargeable
NiCd/NiMH/Li accumulators are recommended. |
| |
|
| |
|
| |
Line input
|
| |
Some users may require a line-input to apply
audio signal externally with a wire. Differential line-in pins (+-7V max)
are available on the Control Board (P9 and P10 pins). |
