DSD 2.8MHz & 192kHz hi-res for top quality.
In modern society, artificial noise is everywhere, and methods like walls or earplugs are often insufficient.Because of this, many people suffer from sleep disturbances and a lack of concentration in office environments.
Brown noise is a powerful method that masks unwanted sounds by playing audio frequencies close to the noise, making it less perceptible.
However, the long-term effects of listening to artificially generated sounds remain largely unclear from a scientific standpoint.
NNTM (Natural Noise Therapy & Meditation) is brown noise recorded 100% from nature, inspired by how, since ancient times, people have used natural sounds—such as rivers—to block noise and maintain acoustic privacy.
By shutting down artificial noise with maximum consideration for human health, it helps achieve high performance, better sleep quality, and stress reduction.
Recommended for those who
- Struggle to sleep due to noise
- Want to improve sleep quality
- Wish to block out voices and sounds in an office
- Need to concentrate on work
- Feel uncomfortable listening to artificially generated sounds for long periods
In fact, we use it ourselves on a daily basis and have confirmed its effectiveness.

*1 This method converts a wide bandwidth directly into 1-bit digital data, expressing the amplitude of the audio signal via pulse waveform density. It closely resembles the compression and rarefaction of sound waves in air and is considered capable of reproducing the original sound more faithfully.
*2 The audio source used in this product has been converted to a 192 kHz/24-bit PCM format, which is the maximum supported for playback on iPhone. When using the built-in speaker of an iOS device, playback is limited to approximately 48 kHz. For native 192 kHz/24-bit playback, please either use an external DAC device or connect directly to a hi-res compatible speaker via a Lightning/USB cable.
