Mendi, Muse 2, Biofeedback and Mindfulness Meditation

Biofeedback is a type of therapy where you use information about your body, as registered by biofeedback devices, in order to improve your thinking and emotions. The theory is that by getting feedback about your internal state of calmness or agitation, you can teach yourself how to become more calm. In the past I used a Muse 2 to help me with mindfulness meditation, and now use a Mendi.

Mendi is a new biofeedback device for $299 US. The way it works is you try to move this ball on the screen upwards instead of downwards. The more often you move the ball upwards, the higher the score you get. From what the company says, people can usually figure out on their own how to get the ball to move upwards. I find this frustrating, and instead I spend my time in mindfulness meditation while wearing Mendi. This works for me, since I often get good scores and the ball moves upwards alot.

I contributed to the fundraising project, and hence received an early bird Mendi device before it was released. The problem I have with Mendi, is that often my Samsung Android phone does not connect with the Mendi device. This problem connecting happens maybe 25% – 33% of the times I use Mendi.

I know from my computer tech experience that computer devices are a combination of hardware and software. Often times, software or firmware updates can improve the performance of the hardware and solve bugs. Hopefully Mendi will release a software or firmware update to solve this connection problem. If it doesn’t, I will still keep and use my Mendi.

I had the Muse 2, $299 US, for a number of months, but I started to feel pain in my forehead just behind the device when I put it on. It was so black and white, since when I put it on, I felt the pain under the Muse 2, and when I took it off, the pain went away. So I sold it on eBay for a decent price. I did some google searches about the problem, and also contacted Muse 2 support about it, but didn’t find anyone with similar experiences.

A great feature about Muse 2 is that they combine mindfulness meditation with their biofeedback device. They have many different meditation options and scenarios to choose from, making it superior to Mendi in that way. However, because of the pain I felt in my forehead, I couldn’t use it anymore. Mendi promises to improve their software as time passes, so hopefully they will become more competitive with Muse 2 in the meditation department.


  1. I recommend Muse 2, I was commuting in south Florida, I started doing it 5 minutes a day, I was able to feel change with aggressive drivers.
    I notice an ability to calm myself and to get my self control under control, same with upsetting meetings.
    Research seems to have result in just 15 minutes a day.
    With mendi it is actually hard to see a difference.

      Thanks for your comment Philippe. I would have kept my Muse2 if I hadn’t had felt a little bit of pain, as I explained in the blog. The meditation and mindfulness programs they include are worth as much as the biofeedback device I think. That’s cool you found a difference with aggressive drivers and upsetting meetings. It feels good to find things, technique, or tools that help eh?
