5 Examples of Earpiece to Hear Far Away

1. Using a Mobile Phone And Bluetooth headsets or Earpiece

To do this, you simply need to go into your mobile phone's settings and then change answering mode to Auto; this enables your phone to answer automatically when you ring it. Most mobile phones only work in the Auto answer mode, after you have plugged in the headset.

After turning on the Bluetooth headset, make sure it's properly paired with your cell phone, and confirm the battery has adequate charge. Hide your Bluetooth headset somewhere you know it'll pick up the sounds clearly, however, make sure that it's well hidden.



2. Using a Two Way Radio and Earpiece

Two way radios allow users to communicate when they're far away such that they can not hear each other. These devices use radio frequencies instead of cell phone towers which means they will work in areas where there's no cell phone coverage or reception.



3. Ear Spy Application


4. Spy Glasses


5. Micro Air Vehicles (MAVs)

Modern technological advances are ever increasing human's potential for developing tiny things. As for the United States Air Force, this translates to revolutionary designs in the air vehicles to provide the war fighters with new tools which can enhance both the situational awareness, and also the capacity of engaging quickly, accurately, and with minimal collateral damage. This is where Micro Air Vehicles (also known as MAVs) come in. The term MAV or micro air vehicle, refers to the a new type of advanced remotely controlled aircraft (abbreviated as, UAV) that's significantly much smaller than other similar aircraft. Typically, MAVs can easily blend in with the surrounding environment, stay in air for a long period of time, and can go places which can't be reached safely by humans, or most of the other types surveillance equipment.




Some of the above points are illegal, and you should not do any of them. Also, do not use any of the above methods to record any intimate relations; the legal consequences of doing so are very severe. Finally, keep in mind that it's illegal in the US to make recordings of people without their consent/permission; and depending on what you'll do with the recordings, you might find yourself in big trouble.

Ham radio: A last resort when phone lines fail





â€œThe only communication out there on 9/11 was amateur radio,â€ Kyvig recalled. â€œThe telephone lines were jammed and no one was going in or out.â€

On the days following that horrific attack, Kyvig assumed the role of messenger, relaying messages from Manhattan to loved ones in the area by calling or knocking on their door. His house calls would go like this: â€œI am Bob; I am a ham operator. I just communicated with your loved one; they are fine and doing well and they will talk to you soon.â€


When Hugoâ€™s tornado struck in 2008, he and wife Jill remained on the radio as long as they could but had to abandon the â€œham shackâ€ as the storm approached. The tornado did $30,000 damage to their home, including Kyvigâ€™s outside antennas.


That connection to people is what Kyvig most enjoys. He chats on the radio to people heâ€™s never met around the world.

â€œItâ€™s a worldwide network of people enjoying fellowship with other hams,â€ Kyvig said.

The radio operator answers calls for help in areas of â€œhealth and welfare,â€ and was on Centervilleâ€™s first CERT (citizen emergency response team), which is now inactive. He serves as a severe weather spotter too, and gains â€œinsightsâ€ as to what is happening around the world by chatting to foreigners.

â€œWe talk about everything from fishing, to weather and local problems,â€ he said. â€œItâ€™s very interesting because you find out so much about people across the world. And itâ€™s not just the personal part but handling messages for help in disasters.â€

Heâ€™s listened to astronauts aboard the space station and scientists at the South Pole. He has talked to people in Russia, New Zealand and most of Europe. For a long time, he kept a conversation going with a man in Norway who lived close to some of his relatives. Wife Jill also has her ham license and enjoys talking to other women, known as YLs or young ladies, across the world. â€œLord knows what theyâ€™re talking about,â€ Bob said. â€œI leave the room.â€

Ham buffs do have opportunity to meet at events called â€œeyeball picnics.â€ The Kyvigs traveled to a picnic in Branson, Missouri earlier this summer to socialize with other hams and match voices with faces.


â€œWe could be talking to people the FCC thinks is a bad guy,â€ he said. â€œBecause we can transmit all over the world without a phone line, some use it to their own means.â€

Other countries have comparable agencies.


â€œThe concept is simple,â€ he added. â€œWe use what Mother Nature has provided: airwaves. We plug a number in for a country and anyone can answer.â€


Jill proudly pointed out that Bob earned a masterâ€™s degree from The 3905 Century Club. Itâ€™s not the typical academic degree, but a difficult achievement nonetheless. â€œThe degree was a challenge,â€ he said, which explains why only 68 radio operators have received the degree since 1967.


Invented in the early â€™20s, ham equipment is evolving, but affordable. Newbies can do it for about $300, he said. There are antennas on his roof, but mostly they are horizontal wires stretched between a tree and the house. Generator backup is used if thereâ€™s a power outage. He also keeps a mobile 12 volt transmitter that he can use in his truck to chat while heâ€™s driving.


When heâ€™s not on the radio, Kyvig enjoys making furniture and fixing TVs. He retired from a career in computer operations about five years ago.
