Easy to use
The device is easy to control with 1 button on the casing. Recording is started and stopped with just one button.
All solutions responsible for the quality of recorded audio are enclosed in an aesthetic and elegant body, ensuring complete discretion. The device looks like an ordinary key, further enhancing its invisibility.
Voice recorder memory
The voice recorder has a built-in 16GB memory, which allows for storing recordings in various formats and qualities:
- 128kbps – up to 320 hours of recordings - MP3/WAV format
- 256kbps – up to 180 hours of recordings - MP3/WAV format
- 512kbps – up to 90 hours of recordings - MP3/WAV format
- 1024kbps – up to 45 hours of recordings - MP3/WAV format
Other files can also be stored on the voice recorder's disk.

Operating modes
- 1 - Continuous
- 2 - Voice-activated
The first mode is responsible for uninterrupted recording, meaning from the moment the device is switched on in this mode, the voice recorder will record for up to 20 hours.
The second mode, in turn, activated by voice, does not record all the time, but only records content when it is spoken. Thanks to this capability - sound detection - you can be sure that the files saved on the device will record speech in its entirety, and thus will not be devoid of meaning or context.
This way, you will also extend the device's operating time, as it will lose energy and memory more slowly. In this mode, the voice recorder will work for up to several hundred hours.
Such a solution makes the voice recorder very versatile and will be useful both when it needs to be left for a longer period and for recording specific meetings. Ideal for teachers, students, journalists, lawyers, businessmen, older people... it will work anywhere and in any situation.

Noise reduction
The voice recorder is equipped with an advanced noise reduction function that blocks ambient sounds, ensuring clear recordings. The responsible function "GAIN" allows for microphone sensitivity adjustment in the range of 0 to 7, which enables precise adaptation of the recorded sound level to environmental conditions.
VOR System
One of the distinguishing features of the voice recorder is the VOR system (Voice Operated Recording). This technology automatically starts recording when sound is detected and stops when the sound fades. This solution helps save space in the device's memory and increases ease of use.

Bitrate Adjustment
The voice recorder offers the ability to adjust the recording bitrate, which allows for selecting the sound quality appropriate to the user's needs.
Thanks to this function, you can balance the quality of recordings with the amount of available memory on the device, choosing one of five available options (from 0 to 4).
Automatic recording splitting
The voice recorder is equipped with a function for automatically splitting recordings into equal segments – e.g., every 30, 60, or 120 minutes. This makes it easier to manage long files, listen to them, and archive them.
Each meeting, lecture, or conversation can be saved in separate files, increasing convenience. An ideal solution for students, journalists, or individuals recording longer events.
Loop recording
Loop recording mode enables continuous operation of the device – when the memory is full, the oldest files are automatically overwritten. This means there is no need to manually delete recordings, and the device can operate uninterruptedly, e.g., in a car, office, or during discreet monitoring. You can be sure that the newest material is always being saved.

Exceptional Functionality
The voice recorder stands out with its exceptional functionality thanks to the built-in headphone output (headphones included in the set). Now you can conveniently listen to your recordings in the library, cafe, or while traveling, without disturbing others and enjoying privacy. The voice recorder has the ability to fast-forward/rewind recordings, which greatly facilitates managing audio files.
Additionally, the voice recorder will serve not only as a reliable recording device but also as a high-quality music player.
The recordings are exceptionally clean and clear, ensuring comfort during listening. The ability to play recordings directly from the device makes it even more versatile.
