How To Eavesdrop Through Walls?

If you want to hear neighbors through walls then there are different ways to do it, some are more effective than others. You can use any of these methods which you find more feasible to you.

1. Using A Glass

This may sound like a silly way to listen through walls but it works in most cases. All you have to do is get an empty glass and place it against the wall you wish to listen through. Make sure you place the rim of the glass on the wall and listen through its bottom end.

You can even make use of a sound amplifier app which you can download from the App Store and Play Store to hear through the wall even more clearly. All you have to do is place your phone microphone at the bottom end of the glass while listening through the wall and it will record and amplify the sound coming through the walls for you.

You can then download the amplified sound and listen to it. This method will only work if the wall thickness is not too much. If the wall is very thick then the sound may not travel through the glass. Don’t worry, keep reading as other methods may help you listen through walls without a glass.

2. With A Spy Stethoscope

A spy stethoscope is a device invented to listen through walls, it will help you hear through thick walls as well. Here’s what a spy stethoscope looks like. It has an amplifier built-in so you will be able to listen to the conversation very clearly.

You can also make use of a medical use stethoscope which you can get from Amazon for this purpose. But it won’t be as effective as the spy stethoscope to listen through walls.

3. Listen Through Walls App

You will find lots of listen-through-wall apps on the iPhone and Android stores. What they do is amplify the sound so that you can hear distant conversations. However, these don’t work if there’s a big obstacle in between for example a very thick wall. You can give them a try as they are mostly free to use but don’t expect too much from them. An example of a listen-through-wall app is Ear SPY.

4. Using An Audio Bug

An audio bug is a listening device that is disguised in the form of daily-use items such as a pen, USB drive, etc. You can easily place these audio bugs in someone’s room and it will record all the conversations without them knowing.

What you can do is purchase one such spy-listening device online and bug a room with it. Since these bugs look like household items, no one will doubt that these are audio bugs, and you can easily record their conversations.

5. Using A Spyware

Spyware can also help you spy through walls with Android and iPhone. Now you must be thinking how can you hear through walls with Android and iPhone using spyware, right? Well, you can. What you can do is either install the spy app on your spare phone and leave it in the room you wish to listen to. Or you can install the spy app on the phone of the person who lives in that room whose conversation you want to listen to.

Once the app is installed you can listen to phone surroundings of Android and iPhone and that too remotely. You can make use of the FlexiSPY app for this.

If you can somehow install the FlexiSPY app on the target person’s phone by having physical access to it then not only can you hear their conversations but also read their text message, record their cell phone conversations, and whatnot.

Once the app is installed on the target phone, you have to go to the FlexiSPY dashboard and select the Ambient option. Under this option, click on the Record option.

So these were some tricks using which you can easily listen or spy through walls. But can you also see through walls? Well, let’s discuss that in the next section of the article.

How To See Through Walls?


We all wish we could have X-ray vision like Superman so that we can also see through walls. However, that’s not possible, and there are not even any gadgets in my knowledge that can allow you to see through walls. But don’t worry there are always alternatives to everything, which I am going to discuss below.

1. Reverse Door Peephole Viewer

If you want to see what’s happening in a room you can do that by making use reverse door peephole viewer like this one. This device will allow you to see through the door peephole from the outside. So that you can see what’s going on on the other side of the door.

2. Spy Binoculars

With spy binoculars, you can easily spy on your neighbors through their windows. Although there are lots of limitations to this method, it is still worth a try.

3. Spy Camera

You can also bug a home with a hidden spy camera and record whatever is happening there without peeping through the windows. You can use a spy pen camera with an audio recording facility and leave it in the room of someone who you wish to spy on. It will record their activities as well as their conversations and they wouldn’t even doubt that a pen could be recording them.

4. Spy Apps

With a spy app like FlexiSPY which I discussed above, you can even record the video through the target’s cell phone remotely. All you have to install the app on the victim’s phone or install it on your phone and leave it in their room. Next, you need to go to the RemVideo option on your FlexiSPY account dashboard and click the RemVideo button.

Final Verdict

“Walls have ears” so you can hear through them. However, you may not be able to do that with only your ears. You will need special devices such as a spy stethoscope, audio bug, etc. to spy through walls. Sometimes a glass is enough to listen to a conversation happening on the other side of the wall. If you want to see as well as hear through walls with Android or iPhone then I would recommend you make use of spyware such as FlexiSPY as it can do both for you and that too secretly.
