In this day and age, there are plenty of reasons to want to record your conversations. The thing is, you don’t always want the other person to know you’re recording them, and in single party consent states, that’s perfectly fine. But, how would you go about this? You can’t just put your smartphone on the table and record, can you?

Well, that’s where something like the best spy voice recorder comes into play. They’re small devices that run off batteries and can usually record for an extended period of time before they need to be recharged. There are many of them out there, though, so how do you choose the best one for you?

We’ve got the answer, in the form of a list of best spy voice recorders on the market today. We have four, and they’ve all proven to be excellent performers. 

Top 5 Bug Detector This Year


Recording: 13 hours
Battery: 110 mAH
Memory: 16 GB

Our Pick

The RECJOY is our top pick for the title of best spy voice recorder, for a few reasons. To begin with, it’s really small and easy to conceal. It comes in a metal case with a male USB plug, which you can use to charge. Just plug it in your computer, and it’ll charge.


  • With a fully charged battery, it can record up to 13 hours. Thanks to the 16GB of built-in memory, you can expect up to 72 hours of recording before you need to empty it. You can transfer the files by, you guessed it, plugging it into your PC or Mac.

  • The RECJOY performs great, thanks to the chip that’s included inside. The noise reduction chip helps the recorder get exactly what you want, without too much extra noise. Using it is easy – all you need is a single key to record and save, so it’s really user friendly.

All things considered, we wouldn’t hesitate to recommend the RECJOY recorder, whether you’re just recording lectures, or your conversations.

Recording: 12 hours
Memory: 8 GB

Runner Up

Our runner up is just as good as our top pick, but unfortunately, comes with a bit less memory. This is another small recording device with built-in memory, but this time you have 8GB. You’ll need to empty it a bit more often, but aside from that, it’s just as good.

There’s no flashing light or anything else indicating that it’s recording, so you can leave it on the desk and nobody will notice it’s not a regular flash drive. The battery is good to go for around 15 hours of recording, and recharging it again is just a matter of plugging it in your computer.

This is also how you transfer the files to your computer, so it’s really, really simple. If you’re looking for something concealable that works great, and don’t mind emptying it a bit more often, the Lgsixe Voice Recorder is a great pick.

Recording: 24 hours
Memory: 8 GB

Also Great

You might be noticing a theme here, but the SOTA is yet another voice recorder that looks like a regular flash drive. It’s small, black and inconspicuous, and chances are nobody will notice it’s not a flash drive – which is just what you want.

It comes with 8GB of memory, which should be good for around 288 hours of recording at the quality it records at. The battery will go for around 24 hours in continuous mode, which is also impressive.

You can trigger the recorder in two ways. There’s a switch that you can move to either side, and it starts recording. Or, if you only want to leave it somewhere, you can also have it activate with voice. The next time it hears a voice, it’ll start recording automatically.

Charging the recorder, and transferring the files, is done in the same way – just plug it in your computer and you’re good to go. The recordings are all saved in mp3 format, to preserve quality and guarantee compatibility with just about any device. All things considered, a great option if you want to keep it hidden.

Recording: 24 hours
Memory: 4 GB
Battery: 120mAh 

The last recorder on our list doesn’t look like a USB drive, but it’s just as small and inconspicuous. It’s really intuitive and easy to use, so even people who haven’t used a voice recorder can find their way around it. 

You can have it start recording when it detects a voice, or you can trigger it manually, and it will record for up to 20 hours at factory settings, at 192kbps. There is a selectable level for the voice activation, and you can also add a time and date stamp on the audio file.

The best thing about the Atto is that all the files can be password protected. Even if someone gains access to your device, they still won’t be able to access your recordings, which is great. Also, their technical support promises that you’ll get a response in no more than a few hours. If true, this is great.

Buyers Guide

A few things to note

Even though short, we did think it’d be nice to include a buyers’ guide as well. We’ll just briefly mention a few key points to remember when buying such a device, and let you choose from our best spy voice recorder options.

The key thing about a recorder is the quality. However, since all of the above give you great quality, let’s talk about what differentiates them – memory and battery life. Memory is something you can live with. Even if you have less of it, you can just transfer the recordings more often, and have your problem solved. However, with the battery life, you’ll want as much of it as possible in order for the recorder not to cut out when you need it.

Aside from these few things, whichever one you choose from the ones above, you’ll be set to go. They all work great, they’re all small and easy to hide, and they’re all a close competitor for the title of best spy voice recorder.

Wrapping things up

If you are to consider everything we said above, choosing the best spy voice recorder isn’t all that difficult. However, we would advise that you check your local laws before you record someone without their consent, as this can be illegal. Make sure you know what you’re getting into.
