The earbudsfor cognition
Targeted nerve stimulation. Built for deeper focus, faster learning and stronger memory.

Built for a sharper mind.
Three outcomes drive everything we’re building at CYMBA.

Deeper focus
Give demanding work your full attention.
Faster learning
Build understanding. Develop new skills.
Stronger memory
Keep what you learn. Recall it when it matters.
How it works
Premium sound x Neurotech
Brain sensing, targeted nerve stimulation and high quality audio in one system, built around the way you think and work.

Sense your state.
Integrated EEG sensors track brain activity, while PPG tracks your pulse. Together, they help estimate mental load and fatigue.
Time the stimulation.
CYMBA One uses those signals to time gentle stimulation of the vagus nerve at the ear around your changing needs.
Put cognition first.
Deeper focus. Faster learning. Stronger memory. The outcomes driving every part of CYMBA One.
Everyday use
For your nextbreakthrough.

Study
For working through complex ideas and building lasting understanding.

Deep work
For the projects and problems that need your full attention.

Learning something new
For building a new skill, one practice session at a time.
Lifestyle visualisations.
FAQ
About the earbuds
What is CYMBA One?
CYMBA One combines wired audio, brain-activity sensing (EEG), pulse sensing (PPG) and electrical stimulation at the outer ear. The product is currently in development.
How does the nerve stimulation work?
Contacts on the earbuds deliver small electrical pulses through the skin of the outer ear, targeting a branch of the vagus nerve. This is called transcutaneous auricular vagus nerve stimulation (taVNS). No implant is required.
Can I listen without using stimulation?
Yes. Stimulation is off by default, so you can listen to audio without starting a stimulation session.
Will it work with my phone or laptop?
CYMBA One uses a wired connection. The connector type and supported phones and computers are still to be confirmed.
Evidence, safety and privacy
What is the science behind CYMBA One?
Human studies have demonstrated improvements in learning and cognitive control with non-invasive vagus nerve stimulation. CYMBA One brings this science into everyday earbuds, combining targeted ear stimulation with brain and pulse sensing.
Is it safe?
Non-invasive ear stimulation is generally well tolerated in human studies, with over two decades of research behind it. CYMBA One uses external contacts, requires no implant and keeps stimulation off until you choose to start. Reported side effects are usually mild and temporary, such as tingling or ear discomfort.
What happens to my brain and pulse data?
Brain and pulse signals guide stimulation timing. EEG sensors measure electrical brain activity, while PPG sensors track pulse. Details of how CYMBA One processes and stores those readings have not yet been published. This website does not collect brain or pulse data.
