Why 852 Player Plus
Built for people who own their music — and want to hear it differently.
-
Third-Eye Tone
The sixth canonical solfeggio frequency — traditionally associated with the third eye and intuition.
-
Quietly Lifting
A higher tone than the working frequencies, often used at the end of a meditation session as the ladder out.
-
Real-Time Retune
Listen to your library at 852 Hz. Switch back to 440 any time.
-
Patent-Protected
US Patent 11,836,330. $19.99 one-time per platform.
How it works
Real-time retuning. No re-encoding. No quality loss.
We don't make copies of your songs. We don't apply equalization or compression. We shift the pitch of the audio stream as it plays — and that's the entire trick.
- 01
Add your music
Point 852 Player Plus at a folder on your device — MP3, FLAC, WAV and most other common formats are supported. Your files stay where they are; nothing is uploaded.
- 02
Tap to retune
One tap and the entire library plays at 852 Hz. The original files aren't touched — the retune happens in real time on the way to your headphones.
- 03
A/B as you go
Switch back to 440 Hz any time. Compare the same song side-by-side and decide for yourself. Set a sleep timer, build playlists, listen offline.
Why we built 852 Player Plus
