Made for the 9pm desk
The lamp is on. The tea is warm. You have one thing to finish — and for once, you actually want to sit down and do it. That's the feeling these tracks are built around: a steady, warm background your attention can lean against, instead of a silence you have to fight.
Six tracks use a 40 Hz binaural layer; Wind-Down uses 6 Hz and Sleep Drift uses 2.5 Hz. The music plays on speakers too. Use stereo headphones to hear the separate tone in each ear. Choose the sound you enjoy; a particular frequency is not a promise of better focus.
€15. Once. Yours forever.
Download once and play in your own audio player. No recurring payment, no ads in the files, and no internet needed after download. Includes all eight tracks and the quick-start PDF.
Honest answers
Will this actually make me focus?
No soundtrack can guarantee focus. These tracks give you a steady background and a repeatable starting cue. The previews let you judge the sound before paying. The kit is a music and relaxation product, not a treatment.
Why not just use free YouTube tracks?
Free streaming tracks are a useful option. Choose the kit if you want files you own, ready-made 25–60 minute sessions, and playback without ads, recommendations or an internet connection.
Do I need headphones?
Yes, for the 40 Hz layer — binaural beats work by playing a slightly different tone in each ear. The music is lovely on speakers, but the frequency effect needs headphones.
What exactly do I get?
Eight stereo MP3 tracks (192 kbps, 5 hours 10 minutes total, embedded album art) plus a quick-start PDF guide, delivered by Gumroad. The audio download is about 447 MB. Use an MP3-compatible player on your phone or computer; transfer or import the files into that player for offline listening.
Is this medical?
No. It's a relaxation and focus aid for general wellbeing — not medical advice or treatment. If you have epilepsy or a seizure disorder, check with a doctor before using brainwave-entrainment audio.
