【24-Hour Limited Price Drop】 Mademoiselle Ai "Frequency Set"

To celebrate my personal anniversary, I'm offering a significant price reduction for 24 hours only.

¥50,000 → ¥33,333

This item was purchased in 2024 and has been carefully stored at home after being used once.
It can freely output sound at various frequencies from the speaker.

You can set and generate any frequency you desire. Power is required in two locations: the main unit and the speaker. The speaker can also draw power from a computer or other devices, allowing the main unit to operate with power from just one source.

It is said that the human hearing range is typically from 20Hz to 20,000Hz. However, in reality, this range narrows with age, and frequencies above 15,000Hz are only audible to younger individuals.

This frequency set can generate frequencies from 1Hz to 20,000Hz. You can listen to any frequency you need. The volume can also be freely adjusted, so you can use it as background music or play it at a low volume while you sleep.

It is very easy to use.

* For shipping, the speaker and other accessories will be placed in their dedicated box, and the cords will be sent in a separate bag (please refer to image 5).
