Key takeaways
- A binaural beat is a pulse your brain creates when each ear hears a slightly different tone. You need headphones.
- A 2019 meta-analysis of 22 studies found a medium average effect on memory, attention, anxiety and pain.
- A 2023 review of 14 EEG studies found only 5 supported the idea that beats entrain brainwaves; 8 contradicted it.
- A small trial in children with ADHD found no effect on attention tests. Binaural beats are not a treatment.
What are binaural beats?
Play one steady tone in your left ear and a slightly different tone in your right, for example 200 Hz and 210 Hz. Neither ear hears a beat, yet you perceive a soft pulse at the difference, here 10 times per second. That pulse is a binaural beat, and it is made by your brain, not the recording.
The effect was first described by the physicist Heinrich Wilhelm Dove in 1839. Gerald Oster's 1973 Scientific American article, "Auditory Beats in the Brain", made it famous. The idea behind focus playlists is that the pulse nudges your brainwaves toward the same frequency, a claim called entrainment.
Do binaural beats work? What the studies found
The most cited evidence is a 2019 meta-analysis by Garcia-Argibay and colleagues. Pooling 22 studies, it found a medium overall effect (g = 0.45) on memory, attention, anxiety and pain. Effects were larger when people listened before the task, or before and during it, and with longer exposure.
The problem is the mechanism. A 2023 systematic review in PLOS ONE looked at 14 studies that recorded brain activity. Only 5 supported entrainment, 8 contradicted it and 1 was mixed. The authors called the evidence inconsistent and the methods too varied to compare.

Newer trials keep the picture mixed. In a 2025 study of 64 students, beats did show up in brain recordings, yet on average they did not slow the decline in sustained attention; one gamma setting helped only when white noise was added. A 2023 home study of 1,000 people found that listening to binaural beats lowered scores on a reasoning test.

Are binaural beats worth trying for focus?
Worth a try
- A meta-analysis of 22 studies found a medium average effect on attention and memory.
- They are free, and at a safe volume the risk is low for most people.
- Listening before a task looked better than listening only during it, which is easy to test.
- Even if the effect is partly expectation, a reliable start ritual still helps some people work.
Don't count on it
- Most EEG studies do not support the brainwave theory the marketing relies on.
- Several trials find no benefit, and one large home study found a drop in performance.
- Studies use different frequencies, durations and tasks, so no setting is proven.
- Many products make medical-sounding claims the research does not back.
Treat binaural beats as an optional extra, not a focus tool you depend on. If you try them, compare a week with and a week without on the same task, and keep the volume low.
Why do some people swear binaural beats work?
Three things can make a session feel better even if the beat itself does little. Putting on headphones blocks out the room. A steady drone masks voices and other sounds that pull attention. And the ritual of pressing play tells your brain the work has started.
Expectation matters too, which is why good studies compare beats against a sham sound that sounds similar. That is the comparison that tends to shrink the effect. None of this means you should stop if they help you; it means the helpful part may be the routine, which you can keep with any steady, lyric-free sound.
Binaural beats vs. isochronic tones vs. white noise
Isochronic tones are a single tone switched on and off at a set rate, so they work on speakers as well as headphones. They are marketed with the same brainwave claims, and their evidence base is smaller still.
White and pink noise are simpler: a steady hiss across many frequencies. For attention tasks, they have the clearest research of the three, including a 2024 meta-analysis that found a small benefit for children and teens with ADHD and a small cost for those without it. If you want a sound to test first, plain noise is the better-studied place to start.
Do binaural beats help ADHD?
There is no good evidence that they do. In a randomized, placebo-controlled pilot, 20 children and teens with ADHD listened to binaural beats or a sham sound for 20 minutes, three times a week, for three weeks. There were no significant differences on attention tests, although parents reported fewer homework problems.
Binaural beats are not an ADHD treatment. If attention problems are affecting school, work or home life, talk to a clinician. Our guide to music for ADHD focus covers the stronger evidence on white noise and lyrics.
How do you try binaural beats safely?
A safe, honest test
Use headphones at low volume
The WHO says 80 dB is safe for up to 40 hours a week and suggests keeping devices at or below about 60% volume. The beat works at a whisper.
Start before the task
In the meta-analysis, listening before a task, or before and during it, did better than listening only during it.
Give it time
Longer exposure tended to work better. Try 20 minutes or more rather than a few seconds.
Compare with and without
Do the same kind of task for a week with beats and a week without. Count what you finish, not how it felt.
Check your health first if needed
Medical guidance suggests people with epilepsy or seizure disorders talk to a doctor before using binaural beats. Never use them while driving.
How does Boulevard's Focus Mode use binaural beats?
Boulevard's Focus & Study mode plays only tracks without lyrics, mixed on the beat, mostly deep and wordless Afro house right now. On the web, it also plays a very quiet binaural layer far below the music. You need headphones for that layer to do anything; on a speaker it is just a faint hum.
We added it because some listeners like it and the risk at that volume is tiny, not because the science is settled. It is not a treatment for ADHD, anxiety or anything else. The lyric-free, gap-free music is the part we would bet on.

Frequently asked questions
Do binaural beats really work?
The evidence is mixed. A 2019 meta-analysis of 22 studies found a medium average effect on memory, attention, anxiety and pain, but a 2023 review of brain-recording studies found the entrainment theory inconsistent, and some later trials found no benefit or a drop in test scores. They may help some people a little; they are not proven.
What frequency of binaural beats is best for focus?
No frequency is proven best. Focus products usually use beta-range or gamma-range beats, and the meta-analysis found effects depended on frequency, but studies use different settings and tasks. A 2025 trial tested 16 Hz and 40 Hz beats and found the 40 Hz setting helped only when white noise was added. Pick one and test it on yourself.
Do you need headphones for binaural beats?
Yes. A binaural beat only exists when each ear hears its own tone. Through speakers, the two tones mix in the room before they reach you, which creates a different, ordinary beating effect or nothing noticeable. Over-ear or in-ear headphones both work, at a low volume.
Are binaural beats safe?
For most people at a low volume, the risk is small. Keep the volume well below maximum, because long exposure at 85 dBA or more can damage hearing. Medical guidance suggests people with epilepsy or seizure disorders talk to a doctor first. Do not use them while driving or doing anything that needs full alertness.
Are binaural beats good for ADHD?
There is no good evidence that they help. A randomized pilot with 20 children and teens with ADHD found no significant effect on attention tests compared with a sham sound. They should never replace an evaluation or treatment plan from a clinician. Steady white or pink noise has somewhat stronger evidence for attention tasks in youth with ADHD.
How long should you listen to binaural beats to focus?
Studies vary, but the 2019 meta-analysis found longer exposure and listening before the task worked better than short bursts during it. A practical test is 20 minutes or more, starting a few minutes before you begin work, at a quiet volume, repeated over a week so you can compare.
