Add that to its viewfinder with a 10x prism optical system which lets the user zoom in closely.
That said, some users have experienced difficulty using the volume control.
Surrounding noise could sometimes interfere or overpower audio sound, or the device could be static altogether, which is why it’s not advisable to use this in a potentially loud location. These experiences, however, vary from person to person.
Also, the dome of the Ex Electronix Express listening device is flimsy plastic so be careful not to break it.

The Ex Electronix called it viewfinder, but Sumas called it scope. Either way, the scope of the Sumas SMH-3010 is an optical system that gives users an 8x closer look at far away subjects.
Also, worth mentioning is the fact that the use of an external recorder is possible with the Sumas SMH-3010 bionic ear listening device.

Additionally, the Bionic ear and booster set plays right into a recorder or a phone and still feeds to the headphones, which is a cool feature.
Although difficult to use in an urban setting, and made with less than perfect material, it still does the job. You should not expect to hear super clear conversations, but this device remains quite useful for detection purposes.
Overall a very good piece of equipment which can be used to record bird calls out in the wilderness, or to pinpoint where a single cricket or frog is calling from out of a chorus.

What Is A Long Range Listening Device?
A long range listening device is normally used by spy detectives and other undercover agents to har conversations from far distances and prevent being discovered.
These devices allow you to pick up even faint voices and sounds from long distances and are essential for some detective work.
Types Of Long Range Listening Spy Devices
In general, there are two types of long range listening devices.
Microphone-Based Listening Devices
Microphone-based listening devices are the most common type as we have covered above. These devices use a sensitive and powerful microphone to pick up long range audio.
The mic is often placed in the center of a parabolic dish and so operates on a point aim and listen principle.
In fact, you can use some of these devices to listen to sounds of even 100 yards away. These types of devices are great for outdoor use because they do well as notice isolation.
Transmitter and Receiver Listening Devices
Transmitter and receiver listening devices use a bug transmitter and receiver. In this case, you have to place the bugging transmitter in the location you want to be listening to. You would then carry the receiver with you.
These devices are great for really long distance listening of up to even 500 meters. However, the drawback is that you have to have access to the location you want to listen to.
How Does a Long-Range Listening Devices Work?
Also popularly known as a parabolic microphone, a long-range listening device is used for collecting and focusing sound waves on a single point.
It works similarly to a satellite dish, but its main advantage is that it has great sensitivity and the ability to focus on one direction. It’s also great at blocking other sounds outside the focus range.
Some of the main uses of such devices include broadcasting, sports events, recording in windy conditions, and eavesdropping on conversations.
It can also be a discrete way of listening to conversations discreetly over long distances instead of planting a bug that can be detected more easily.
How Far Can Listening Devices Work?
What Should You Look For When Buying a Long-Range Listening Device?
There are multiple factors worth considering when looking for the best parabolic listening device to suit your needs. Here are several important factors:
The best long-range listening device will allow you to get the audio with great clarity from a considerable distance. These devices feature a high-tech audio amplifier combined with a noise reduction feature, resulting in high-quality sound.
Low-quality parabolic microphones perform poorly in both fronts, with the result being slightly better than using your bare ears. That’s why most microphone that attaches to your cell phone is popularly known for being poor pieces of listening equipment.
All these long-range listening devices come with different recommended range, and you should adhere to it for the best results.
When considering range, you should also think about whether you need a long range listening device that works through walls.
Keep in mind that the recommended range only works under the ideal condition at a time when the environment is dead quiet, though you might not always get that.
That’s especially true in rainy or windy conditions or when something is obstructing you and your target point.
Some long-range listening devices can record the audio on an SD card or attach a video or microphone recorder easily.
Other parabolic listening devices can only be used for listening, though it’s not as easy to record. That means the parabolic microphone you choose all depends on your needs.
Some of the best parabolic microphones used for long-range listening require a significant amount of battery power, and hence they are difficult to run purely on battery power for a long time.
As such, you should choose a product that uses regular batteries that can last for a couple of hours for the best results.
Overall, the long range listening device which managed to stand out to us was the Sound Shark long range microphone.
Thanks to its ability to cancel out interference and keep noise as low as possible, and ability to pick up audio at an astonishing long range while maintaining a focused pattern, choosing the Sound Shark long range listening device as our favorite pick wasn’t a difficult decision.
At the end of the day, you still want to buy the best you can afford and will give you value for your money.
Keep in mind that “long range” is relative. Parabolic microphones also can’t blast through walls or thick objects. They are dependent on having direct line-of-sight access to the sound source.
Additionally, most listening devices use a 9-volt battery (Detect ear uses two AAA batteries) but don’t come with any. Be sure to check with the seller to know what accessories (if any) are included with your purchase.
If you feel that we left out some other great long range listening devices, don’t hesitate to let us know in the comment section.
Other Stealth Devices
Sometimes you don’t want to be Sherlock Holmes and use long-range listening devices. For example, maybe you just want to ensure the safety of your home and monitor your children, nanny or elderly parents. For this, you could just use a Bluetooth speaker with a hidden camera.
