isochronic frequencies.
you've been sleeping through them.
written by jessica clay, finessed by claude · aug 2026
your brain naturally shifts through different frequencies all day. isochronic tones guide it — gently, while you sleep.
an isochronic frequency is a regular, rhythmic pulse of sound at a specific Hz. your brain picks it up and starts to synchronise — a process called brainwave entrainment. it's not hypnosis, it's not magic (well, it kind of is), it's just your brain doing what brains do: responding to patterns in sound.
unlike binaural beats — which require stereo headphones and play two separate frequencies, one in each ear — isochronic tones are a single continuous tone. no headphones needed. they work through your phone speaker. this is one of the biggest differences between bene and every other sleep sound app out there.
bene uses 6 specific frequencies across its 8 sleep tracks. each one sounds different, feels different, and is matched to a different intention. here's what they actually sound like — and what you'll wake up feeling.
the 6 frequencies bene uses
the warmest frequency in the set. it has a sweetness to it — almost amber-coloured if sound could have a colour. it doesn't demand your attention, it just settles around you.
abundance — attracting abundance
wake up feeling open to receiving more
manifest — dream it real
wake up feeling like the universe is delivering your hopes & dreams
low and grounding. the kind of frequency that gives you something to land in. it settles at the base of everything and makes the rest of your thoughts feel less loud.
confidence — i am enough
wake up feeling like you can conquer the world
rewire — new story
wake up feeling open to change
the quiet one. barely there, which is exactly the point. it settles into the back of your neck and unhooks something you forgot was tense. most people don't notice it until it stops.
calm — quiet the mind
wake up feeling like a weight has been lifted
warm and rounder than 528hz. softer. the frequency equivalent of being held — or of holding yourself, which is honestly better.
self love — open your heart
wake up feeling a little more love for yourself
lighter. almost shimmery. it doesn't sit in your chest the way the lower ones do — it floats just above your shoulders. the kind of sound that makes things feel possible without you having to do anything.
luck — release & let go
wake up feeling like luck is all around you
the brightest of all of them. expansive, like breathing in somewhere with very good air. it opens something up rather than settling something down — and that's what makes it different.
your best life — morning power
wake up feeling like it's going to be an amazing day
you don't have to understand how it works for it to work. you just have to press play.
bene has 8 sleep tracks across these 6 frequencies — each one matched to a different intention, a different version of you. pick the one that sounds like who you want to wake up as.
