Transmitter and Receiver Listening Devices

Transmitter and receiver listening devices use a bug transmitter and receiver. In this case, you must place the bugging transmitter in the location you want to listen 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.


1. Can a parabolic microphone hear through walls?

Walls and glass obstruct sound waves. The amount of sound blocked depends on how thick or well-insulated the wall is. 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.

2. How do you block a parabolic listening device?

To hide the sound, send another sound or completely block the sound. You can also use a device that produces static noises so that the person receiving the audio from a parabolic mic receives distorted audio. These are some ways that helped spies keep the conversations confidential. 

3. Where is the best place to put a listening device?

Some of the best places to put the listening device are:- Lighting fixtures, outlets, and cable boxes, which are all popular hiding places for listening devices. Listening devices can access communications ports, Wi-Fi routers, coaxial connections, and a VOIP trunk.

4. How far can a parabolic microphone pick up sound?

A parabolic microphone can pick up audio from up to 50 meters away. This design has several possibilities, ranging from capturing natural noises and outdoor activities to being employed by law enforcement and intelligence services.


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 its 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 it will give you value for your money.

Keep in mind that “long-range” is relative. 

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 in your purchase.

Other Stealth Devices

Sometimes you don’t want to be Sherlock Holmes and use long-range listening devices. For example, maybe you want to ensure the safety of your home and monitor your children, nanny, or elderly parents. For this, you could use a Bluetooth speaker with a hidden camera.
