How a session works

No setup. Just put it on and plug it in.

There is no setup. No app to download, nothing to pair and no button to press. Put the headset on, plug it in, and that’s all.

ZenBud Series 2, step 1: Put it on
01

Put it on

Place the headset comfortably over your ears, like regular headphones. The silicone pads sit just above the ear canal.

ZenBud Series 2, step 2: Plug it in
02

Plug it in

Plug the USB-C into your phone or laptop. That’s it. It starts working the moment it’s plugged in.

ZenBud Series 2, step 3: Look for the blue light
03

Look for the blue light

No app, no pairing, no charging and no button. Turn the controller around: a blue light means it’s working.

ZenBud Series 2, step 4: Relax
04

Relax

Keep listening to your own music or podcast. You can forget it’s running: it switches itself off after 30 minutes, the most we recommend for one session, and the headphones keep playing.

Why Series 2

Calm without friction.

ZenBud uses gentle focused ultrasound at the ear to support your body’s natural calm response. No app to fight with, no gel on your neck, no shocks or tingling. Just the reset.

ZenBud Series 2: Gentle, not electric

Gentle, not electric

Focused ultrasound instead of electrical current. No shocks, zaps, tingling or conductive gel.

I like the experience I am having from using them

I like the experience I am having from using them. I get a very deep calm and relaxation when I use them. The one piece I am still getting used to is how they feel in my ears. I find the piece that goes into the ears a little irritating but not bad, still something I am adjusting to or feel could be more comfortable.

Worth it

I really enjoy using the Zenbud and have been using it for months. I normally use it before bed while listening to a meditation track on my phone. This is a valuable feature that other devices don't have. I also have a Vagustim but have had numerous issues with it such as random disconnection and earbuds not staying in place. I really like that Zenbud is not Bluetooth for this and other reasons ( EMF).
When I had questions they were responded to immediately and the service has been excellent.

Excelente, realmente a mi hijo (de 22 años con TEA) le ha venido muy bien. Lo relaja, lo cual nos ha ayudado a que maneje mejor su sobrecarga de estímulos que, aunque no es frecuente, ocurre y alteraba su dinamica diaria. Yo tambien lo uso conmigo, me ayuda bastante en el sueño reparador

So far it has not made a difference for my client to any significant degree

So far it has not made a difference for my client to any significant degree... any suggestions as to better use. He dals with severe bouts of depression and anxiety.

Hi Linda! Thank you for taking the time to share your experience with us.

We recommend using ZenBud for 5 minutes each day, as consistency is important. If your client has been using ZenBud consistently and isn’t seeing the results they’re hoping for, they can try gradually increasing the length of their sessions. Just keep in mind that the ultrasound will automatically turn off after 30 minutes.

If you or your client would like more personalized assistance, please feel free to reach out to us at info@neurgear.com. Our team would be happy to help!

ZenBud vs. other vagus nerve devices

Vagus nerve stimulation, without the shocks.

Most vagus nerve stimulators send electrical current through your skin. ZenBud uses gentle focused ultrasound instead.

“My whole neck is twitching.”

“The electrodes contract the muscles in your neck […]”

ZenBud sends no electrical current. Nothing makes your muscles fire.

A shock collar isn’t discreet.
ZenBud is.

Stimulate your vagus nerve at your desk, on the train, before a meeting. It looks like headphones, so nobody knows.

FAQ

Questions, answered.

Still curious? See all FAQs.

How do I use ZenBud?

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.

How do I know it’s working?

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 indicates that the ultrasound is on. You can also play music or other audio through ZenBud just like regular headphones while using it.

How long and how often should I use it?

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.

Is ZenBud safe to use?

ZenBud is compliant with CE standards, and every unit is hydrophone-tested before it ships. It’s a general wellness device, not a medical device, and it hasn’t been reviewed or cleared by the FDA. Use it only as a passenger, never while driving.

Can I use ZenBud if I’m deaf or hard of hearing?

Yes. ZenBud does not rely on your ability to hear. It uses ultrasound for stimulation, which is separate from the audible sound produced by the headphones. This is not binaural beats or a sound track: the ultrasound acts on the auricular branch of the vagus nerve itself, whether or not you play any audio.

Can I pay with my HSA or FSA?

ZenBud is HSA/FSA eligible on qualifying orders, so you can pay with pre-tax dollars. Eligibility depends on your plan administrator. Learn more.

What is the return policy?

Every ZenBud comes with a 45-day money-back guarantee, for any reason. The 45 days start the day your ZenBud arrives, not the day you order. Send it back (return shipping is on you) and we refund the full price. After that, the 1-year warranty covers any defect that isn’t intentional damage, for 365 days from delivery. See the refund policy for details.

Who do I contact for support?

Contact the ZenBud team or email info@neurgear.com.
