Choose the version that fits your recording needs — whether it’s for lectures, meetings, or personal notes.

Question 2: What Material Is the Device Made Of?

The Mini Voice Recorder is built with a durable aluminum alloy body, combining lightweight design with excellent resistance to scratches and minor drops. This sturdy material not only gives the device a sleek appearance but also ensures it can withstand everyday use.

In addition, the recorder features a built-in magnet, allowing it to easily attach to metal surfaces (Steel, Iron, Cast iron, Certain types of stainless steel) like desks, cabinets, or shelves made of steel. While the aluminum body itself is not magnetic, the internal magnet provides secure and discreet placement, making it ideal for hands-free or hidden recording situations.

Question 3: Where is the microphone on voice recorder?

The microphone is discreetly built into the center of the device. While it may not be immediately visible from the outside, it’s specially designed to capture sound from all directions (omnidirectional) within its recording range, no matter where or how you place it.

Question 4: How Do You Charge the Device? How Long Does It Last?

Charging the Mini Voice Recorder is simple. Just plug the included USB-C cable into your laptop or a USB wall charger.
If your device only has a USB-A port, use the included USB-C to USB-A adapter for easy connection to standard USB ports.

• Charging time: About 1 to 2 hours for a full charge
• Battery life: Records continuously for 8 to 24 hours, depending on your settings

This makes the Mini Voice Recorder ideal for long meetings, full-day classes, or discreet all-day recording.

Question 5: How does the LED light work when charging and recording?

The Mini Voice Recorder uses a smart LED light system to show different device statuses. Here's how it works:

1. Charging LED Indicators

• While charging: The LED light turns red
• When fully charged: The LED changes to blue

Note: You do not need to turn on the device while charging.

2. Recording LED Indicators

• Turn on the device (slide the switch to ON): A purple light appears
• After about 2 seconds: The light changes to red
• The red light blinks 3 times to signal that recording has started
• During recording: The LED turns off completely to ensure discreet operation
• When stopping a recording: The LED blinks red once to confirm the file was saved successfully

This smart light system helps you know the device's status while keeping recordings private and unnoticeable.

Question 6: Does the Device Make Any Noise or Light Up While Recording?

No. The Mini Voice Recorder operates in complete silence and does not emit any lights during recording. This ensures maximum privacy and makes it ideal for discreet use in sensitive environments.

Question 7: What Recording Modes Does the Mini Voice Recorder Support?

For ease of use, the recorder comes with three physical switches:

• OFF – Turns the device off completely.
• ON – Starts continuous recording.
• VA – Enables Voice Activated Mode, which records only when sound is detected, saving battery and storage space.

The Mini Voice Recorder offers two smart recording modes to suit different needs:

1. Continuous Recording Mode

• In this mode, you manually slide the switch to turn recording On or Off at any time.
• The recorder will keep recording non-stop until the battery runs out or the memory is full.

2. Voice Activated Recording (VOR)

• Switch the device to VA mode just once, and it will automatically start recording when sound is detected.
• When there is silence, it pauses recording to save memory and power.

These two modes make the mini voice recorder ideal for both everyday use and discreet, hands-free operation.

Question 8: How Should You Position the Mini Voice Recorder to Capture Clear Audio?

To get the best sound quality from your Mini Voice Recorder, follow these tips:

1. Ideal Recording Distance

The recorder can clearly capture sound within up to 15 feet (about 4.5 meters) in a quiet room. For the best clarity, place it 8–20 inches (20–50 cm) away from the sound source, such as the person speaking.

2. Point the Device Toward the Speaker

Although the built-in microphone is omnidirectional (records from all directions), pointing the device toward the person speaking improves clarity—especially in noisy environments.

3. Use the Included Earphones for Close Recording

You can plug the included earphones with microphone into the device and place the mic close to your mouth. This is especially helpful when recording yourself or in a loud environment.

4. Adjust the Gain Level for Your Environment

Open the MRECSET.txt file on the recorder to change the GAIN setting, which controls microphone sensitivity:

• Low Gain (1–3): For quiet rooms or close-range recording
• High Gain (4–7): For large rooms or distant voices

Proper gain settings help reduce background noise and capture voices more clearly.

Question 9: How to Listen to Recordings from the Mini Voice Recorder

There are two simple ways to play back your audio files from the mini voice recorder:

1. Listen Directly on the Device

Use the included earphones and volume control. Just plug them into the device’s headphone jack and you can listen to your recordings without a computer.

2. Listen on a Computer (Windows or Mac)

Connect the recorder to your computer using the USB cable. It will appear as a removable drive. Your recordings are stored inside as .WAV files.

Note: If your computer doesn’t recognize the device or the drive doesn’t show up, follow the step-by-step guide in this article: Quick Fixes for Common Voice Recorder Connection Issues with Your Computer

To play a recording:
