enophone by Mindset Innovation, Inc – a quick review

eno phone
This is the final product. Arrived in January 2022. Ordered May 2018. Was it worth it?

How is it different from a promise? Hardware is awesome – I got a better Bluetooth version, better battery life, and one sensor more.

The app is still developed and it has some issues. And we are still waiting for some features like temporally mute notifications, gentle focus audio cues, rest time suggestion, better graphic look, etc. But, so far, so good.

Whats was the promise?

Usage of enophone

If you turn it on, you hear – power on, battery status, and connected (if computer/phone or something like that catch the Bluetooth).

It fits on the head very well and comfortably. Sometimes I have a problem with the left head sensor because I have more hair. Or my head is not in „ideal shape“. But after some tries is all fine.

Noise cancellation works great. I can switch three modes. Noise cancellation on, talk thru and noise cancellation off. You need only double press the middle button on headphones (easy to find with your thumb) and it switches – you hear audio information which mode is active.

Music sounds very good, communication via Teams, Skype, etc is without problems.

Pictures are better than long writing. Sometimes it freezes on start and I must kill the app in Activity Monitor. But in most cases, it behaves correctly.

Was it worth it?

Almost 4 years of waiting can be frustrating. The truth is that the manufacturer did not want to ship a product that has design flaws. They uncovered a few in the making, wrote openly about it, and explained everything. The other complications were caused by coivd-19, but covid-19 had a global impact.

I have been using the headphones every day for several weeks now. At work, they help me to shield myself from the noise of my surroundings, even when I’m not listening to anything in them. It’s even better with music or spoken word.

Even after a few hours on my head, the headphones don’t bother me in any way. The connectors do not press and are not uncomfortable. The ones on the head bridge can also be removed. I really appreciate the soft microfiber, which is more comfortable than leather. I’ll see how I feel with them in the summer.

The app is still in development and has a lot of room for improvement. Just today a new version 0.6.0 was released, which added a new stats page.

I’m happy with the headset. Would I buy them again? Definitely yes!

P.S.: And yes, I really have them!
