What is the Sens.ai brain training device?

The Sens.ai brain training device is a neurotechnology product that combines 5 brain training technologies into one system. This 5-in-1 system includes neurofeedback, light stimulation technology, heart rate variability biofeedback, brain function assessment, and meditation training.

The science behind Sens.ai is rooted in neurofeedback, a type of biofeedback where real-time displays of brain activity are used to teach self-regulation of brain function. The device uses sensors to measure your brain wave activity and provides real-time feedback, allowing you to train your brain and potentially improve brain functions like focus and concentration.

The Sens.ai device also includes light stimulation, which uses near-infrared light to stimulate brain cells, potentially leading to improved cognitive function. Additionally, it offers heart rate variability (HRV) biofeedback training. This method is used to evoke a certain heart rate pattern, which may positively impact mental and emotional health.

When you use the Sens.ai device, you can expect a personalized brain training experience at home as the device adapts to your goals and real-time biometrics. The Sens.ai package includes one Sens.ai headset, 60-day free membership, one GeniusPulse controller™, one hard-shell travel case, and a charger with regional adaptors.

Pros and cons of Sens.ai

Here are some pros and cons from our Sens.ai review:

Using the Sens.ai neurofeedback device

From our assessment, the device is stress-free to set up and use as the app contains clear and easy-to-follow instructions with some video explanations, from the initial setup to the various training programs available. Below is a short guide on how to get started with the device.


Start by downloading the app from Apple or Google Play stores to your smartphone and ensuring the devices (headset and GeniusPulse controller) are fully charged. When you open the app, on-screen instructions will guide you in pairing your phone/tablet with the headset through Bluetooth twice. The first connection is for data, and the second one is for audio.

Put on the device

You will need to fill up the water brush included with water first (any drinkable water). The app has video and text tutorials that will guide you easily in applying water to the sensors and ensuring that you put on the headset correctly. It also contains instructions on how to use the GeniusPulse controller during an assessment.

Start your session

Sens.ai has three core modes: train, boost, and assess. There are nine ‘train’ sessions that include calm heart, focus, concentration, and clarity training, among others. Some ‘boost’ programs include stillness and social boost. The 'assess' mode includes a 15-minute functional test that scores the brain’s performance in processing new information. It helps determine if the brain training sessions work for the user.

Also, there is a tab called ‘mission’ that provides structured brain training programs focused on a specific outcome. There are 16+ missions, which typically last between three and eight weeks.

Track your progress

Sens.ai records your biometrics, such as brainwave signals and heart-rate variability, during training sessions. Training brain waves may help to improve focus and may promote a calm mind while heart-rate variability training may support better mental clarity and reduced stress.

You can compare your stats over time to see your improvements. The app supports up to five user accounts, so while you can share the headset, we advise not sharing your account as it may hinder personalization and stop you from receiving the full benefits of your training.

The cost of Sens.ai neurofeedback device

The Sens.ai device costs $1500 for a one-time payment, including a headset, a 60-day free membership, a GeniusPulse Controller™, a hard-shell travel case, and international power adaptors. When your free membership ends, you can retain it for $240/year, making $20/month. Membership is optional, as free accounts still have access to some programs.

Shipping is free in the US and Canada. In addition to shipping fees, import duties, and VAT (Value Added Tax) may be charged upon delivery outside the US, Canada, EU, and UK.

Each order comes with a 30-day return policy and a one-year warranty for hardware defects.

Are there any risks in using the Sens.ai device?

The device uses non-invasive technologies that are generally considered safe. However, research data needs to be included in the device's safety profile.

The provider states that the use of the device may evoke strong emotions. People with emotional vulnerability and mental health conditions like post-traumatic stress disorder (PTSD) should consider reaching out to a professional mental health practitioner before using the device.

Lastly, it is essential to note that the FDA does not approve the Sens.ai headset and app and that they are not medical devices. They are not intended to mitigate, prevent, treat, cure, or diagnose any disease or condition.

Sens.ai reviews: customer feedback

Sens.ai has received a variety of reviews from customers across different platforms.

On online forums, users have shared mixed experiences. Some users appreciated the easy setup process and the beneficial effects of the training sessions. However, they noted that the raw EEG data was unavailable to users, limiting the device's usage to the training paths defined by the Sens.ai application. Another user considered Sens.ai to be the most comprehensive and robust among several neurofeedback devices. But, some users have reported technical issues and challenges with customer service.

On Trustpilot, Sens.ai has one review with a rating of 1/5. The user praised the smooth purchasing process and the device's effectiveness for breath awareness training and meditation. However, they encountered issues with firmware updates and expressed concerns about the inability to pause their subscription while troubleshooting the device.

Sens.ai reviews on their official website are also positive.

In our view, Sens.ai appears to offer a comprehensive brain training system that users may find beneficial. As with any product, potential buyers should consider these reviews and conduct thorough research to determine if Sens.ai fits their needs.

Sens.ai review conclusion

We are concluding our Sens.ai review with a section discussing what we like and don’t like about the product.

What we like

In our opinion, Sens.ai has several commendable features. The advanced 5-in-1 neurofeedback system stands out as a significant pro, offering a comprehensive approach to brain training. The device is user-friendly and easy to set up, making it accessible even to those new to neurofeedback.

The fact that it does not require the use of gel is a definite plus, as is its good battery life. The device’s ability to support up to five users makes it versatile for different users or family members. In addition, the one-year warranty and 30-day return policy add to the overall positive customer experience.

What we don't like

The device is unsuitable for users below 13 years, limiting its user base. While the company states that they have ongoing study trials, the lack of existing research data to back the use of the product for brain function enhancement is a concern. The use of Sens.ai may evoke strong emotions, which could be a deterrent for some users.

Lastly, when compared to other neurofeedback devices in the market, Sens.ai is relatively expensive, which might make it less accessible for some potential users.
