Everything you need to know about ZenBud, from your first session to returns.
Put the headset on and plug it into your phone or laptop with USB-C. That’s all. There is no setup, no app to download and no button to press, so you can use ZenBud whenever you need a quick reset.
Plug in ZenBud, and it’s working. The stimulation is subtle, so you should not expect to feel a noticeable sensation during use. A blue light on the back of the Y-connector shows the ultrasound is on.
Aim for 15 minutes, once or twice a day: 15–20 minutes is the sweet spot for your best results. Short on time? 5–10 minutes still lets you feel the shift. Every session switches itself off at 30 minutes.
Yes. ZenBud works like regular headphones, so you can play music, a podcast or nothing at all while the ultrasound runs.
Yes. It looks and works like headphones, so you can use it at your desk, on a plane or on the train. Use it only as a passenger, never while driving.
If you like data, resting heart rate is the most useful place to start, followed by HRV trends over weeks (not day to day). Individual results vary.
ZenBud uses gentle focused ultrasound at the outer ear, where a branch of the vagus nerve sits close to the surface. The vagus nerve is a big part of your body’s rest-and-recover system. See how it works.
Yes. ZenBud does not rely on your ability to hear. The ultrasound is separate from the audible sound produced by the headphones. This is not binaural beats or a sound track: it reaches the auricular branch of the vagus nerve whether or not you play any audio.
Electrical devices send current through your skin, usually with gel on your neck. ZenBud uses gentle focused ultrasound at the outer ear instead: no shocks, no gel, no twitching. See the full comparison.
Time outdoors, good food and less screen time are all worth doing, and we recommend them. But life is busy, and those changes don’t always fit into a hard day. ZenBud gives you a simple 15-minute ritual you can do anywhere. Read the science.

Talk with your doctor first if you have metal in or around the ear, an implanted electronic device, a heart rhythm condition or a history of fainting, take medication that affects your autonomic nervous system, or are pregnant or nursing. If anything unexpected happens, stop and contact your doctor. See our safety and compliance page for details.
