Binaural beats for focus
Pick a brainwave preset, layer it under brown noise, and let the Pomodoro timer drive your session. Free, no ads — and honest about what the science actually says.
Headphones required — the beat is created inside your brain from a different tone in each ear. Speakers can't do it.
1 Pick your state
2 Add a noise bed (recommended)
A bare beat tone is thin. Layer it under a noise color and it becomes a subtle texture — and the noise does the distraction-masking, which is the part with the strongest evidence. Both play together; the volume control in the bottom bar drives the whole mix.
3 Work in cycles — Pomodoro
Starting a session starts the sound; the chime marks each switch. Sound keeps playing if you browse other pages of this site.
What's actually going on?
Play a 220 Hz tone in your left ear and 236 Hz in your right, and your brain hears a third thing neither ear received: a pulsing 16 Hz "binaural beat", constructed in the brainstem where the two signals first meet. That illusion is real, measurable, and a genuinely cool piece of neuroscience.
The popular claim goes further: that the beat frequency nudges your own brainwaves toward it — beta for focus, theta for meditation — a idea marketed as "brainwave entrainment". Here's our honest read of the research: the entrainment effect in EEG studies is small, and behavioral results on attention and memory are mixed. Meanwhile, two boring things reliably help: a steady soundscape that masks distractions (open offices, street noise), and a ritual — the same sound every session tells your brain it's time to work. That's why our tools pair the beats with a noise bed and a timer: the parts that definitely work carry the part that might.
No "digital drugs", no $200 audio programs. Try it for a week of sessions — it costs nothing — and keep whatever genuinely helps you focus.

Frequently asked questions
Do binaural beats actually work?
Honestly: the evidence is mixed. The auditory illusion itself is real and well documented — your brain genuinely constructs a beat that is not in the audio. Whether that beat "entrains" your brainwaves enough to change focus or mood is less settled: EEG effects are small, and behavioral studies show modest, inconsistent benefits. What is solid: a steady soundscape masks distractions, and a consistent "work sound" ritual conditions you to start working. Try 15-30 minutes; keep it if it helps you, drop it if it does not.
Which frequency should I use for studying?
The convention: beta range (14-20 Hz) for active, alert work; alpha (8-12 Hz) for calm, steady focus; theta (4-8 Hz) for meditative states; delta (1-4 Hz) for winding down. Our Deep Work preset uses 16 Hz. But individual responses vary a lot — if a setting feels irritating, change it. Comfort beats theory.
Do I really need headphones?
Yes — this is not optional. A binaural beat is created by your brain comparing a slightly different tone in each ear. Through speakers, both ears hear both tones, the tones mix in the air, and the binaural effect disappears. Any regular headphones or earbuds work.
Can I mix beats with brown noise?
Yes, and we recommend it — that is the point of the noise bed section. The beat carrier is a quiet 220 Hz tone that many people find too naked on its own; layered under brown or pink noise it becomes a subtle texture. The mix also does the distraction-masking work that has the strongest evidence behind it.
Are binaural beats safe?
For most people, completely — it is just quiet sound. Keep the volume low (this is about texture, not power). If you have epilepsy or a seizure history, check with your doctor first: rhythmic stimulation is worth a professional opinion. And do not use immersive audio while driving.
