Description
       Mini wireless earpiece (earpiece) is a micro-mini wireless inductive receiver which transforms audio signal through electromagnetic induction. These products make the covert communication possible when it is inconvenient to expose earpieces. earpiece is widely used in many departments such as FBI, CIA, antiterrorism, security, television and films studio etc.

Features and Highlights
        Small, light, easy to conceal;
        Comfortable for wearing with an optimum anatomic design.

Work principle
        Mini wireless earpiece is a one-way reception equipment driven by electromagnetic induction and is used in conjunction with drive equipments, such as radio and mobile phone.

Structure
        Mini wireless earpiece consists of specialized chip, shell, faceplate, battery door, handle etc.
1. Battery door
       Open battery door by fingertip, install the battery perfectly and push the battery door to battery box.
2. Handle
       Clarity and high strength string help you to take out the earpiece from ear canal easily.

Technical specification
       - Mini wireless earpiece (earpiece) receives signal by inductive coil,
across electromagnetic fields
       - Receiving distance: 50– 70 cm
       - Standard Zinc-air battery: type SONY 337
       - Battery life: about 5 hours
       - Audio bandwidth: from 300 Hz to 4 KHz
       - Distortion: <2%
       - Size: 3x5x7mm
       - Weight: 0.8g (battery included)
       - Working frequency: all frequencies
       - Distance between inductive coil and Mini wireless earpiece: about 70-100 cm.

Application method
       1.Open battery door, install the battery perfectly and push battery door into battery box gently. Put the earpiece into ear canal by holding the handle and the slight sound of current indicate working order.
      2.Adjust the volume of drive equipment to reach satisfaction.
      3.Set mobile phone to automatic return or vibration.
      4.Put the inductive loop around your neck and connect the inductive loop to the drive equipments (mobile phone, radio) which are attached to or beneath user’s clothing. One transmits message with radio, the other wearing an earpiece and inductive loop who also has a radio can hear the message very clear. Because the inductive loop inducts the message from the radio to earpiece and then earpiece transforms the electromagnetic inductive signal to audio signal to reach the wireless inception. Communication distances and radio power are the direct proportion. You can communicate with others freely once network exist when you use mobile phone.

FAQ
How about the quality of the sound of your earpiece? Is there any bothersome noise?
        Absolutely not. The sound is clear perfectly and you can hear every word said by your partner.

Can anyone see or hear that I have a mini wireless earpiece in my ear? What are the sizes?
        Mini wireless earpiece is very small, 3X5x7 mm, has a perfect anatomic design, and so no one will ever notice that you have anything inside your ear.

How are the mini wireless earpiece and inductive loop powered?
    Mini wireless earpiece is powered by a small battery (approximately 15 hours of battery life), and inductive loop is powered by mobile phone.

Why buying mini wireless earpiece rather than something else?
       There are many reasons for that: reasonable price, high quality of sound, supreme quality of inductive loop microphone, small size, perfect fitting in the ear channel, fast delivery, and guarantee etc.

    There are some other technologies, like Bluetooth mini receivers technology. The real problem is that if someone else is having Bluetooth earpiece in the classroom, there will be interference. Our inductive technology has range of working about 40 cm (distance between earpiece and inductive loop), so there is no way of being interfered.
