A desk at night: matte black headphones beside a lit candle and notebook, under a warm brass lamp

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.

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.
