LifeBeam Vi Review

LifeBeam Vi is a set of smart fitness-tracking headphones that promise to give you a personal trainer within your ears. Here’s our review of the Kickstarter-funded LifeBeam Vi.


What Is LifeBeam Vi?

LifeBeam Vi claims to be the world’s “first true AI fitness trainer”. It’s a set of headphones that deliver customized exercise advice directly into your ears. Some are calling it “science fiction made real” while others are calling it one of the most genuinely useful wearables to date.

The headphones are made by an Israel-based company named LifeBeam. That company recently funded its project via Kickstarter.

You may not have heard of LifeBEAM, but they have previously made bio-sensing technology to some organizations you may be familiar with, including NASA, the US Air Force, Samsung, and Under Armour. So yeah, they have the credentials.


How Does Vi Work?

Vi works using a proprietary technology called Awareable. That technology promises to measure more information from your surroundings in order to provide more valuable feedback.

Like most fitness tracker-style devices, LifeBeam Vi tracks things like heart rate and steps.

But it also takes it a step further and measures biometrics like your temperature, elevation, heart rate variability, motion, and other data using environment sensors, an accelerometer, and a six-axis gyrometer. These sensors are described as “aerospace-grade”.

As you may or may not know, you can get a lot of biometric data from the ear. LifeBeam actually believes the ear is more accurate than the wrist:

“The ability to extract accurate data can be found from the ear. It’s stable, much closer to the head and heart, and contains just as much information, if not more. It’s simply a much more perfect place to measure”, explains Omri Yoffe, LifeBeam CEO and co-founder in an interview with

To get a more complete picture of you, Vi will also connect to other health platforms and apps, including Apple HealthKit, Google Fit, Fitbit, Strava, or whatever other device you use to keep track of your health. If you don’t have a current platform, you can also just tell Vi more about you without ever connecting to other apps.

What about sound? Well, LifeBeam has partnered with Harmon Kardon for high-quality sound – so it doesn’t seem to be going cheap an audio quality.

Some are calling the combination of headphones with smart technology “hearables” as a new twist on “wearables”. Other competitors for Vi in that category include Bragi Dash and the Samsung Gear IconX.

How Does the AI Help You Train Better?

Vi’s AI starts off by tracking your movement and starting to learn more about you. When you first turn on your Vi headphones, Vi will tell you “Let’s get to know each other so I can calibrate myself.”

Then, after two or three training sessions, Vi starts to give detailed, customized insights on your exercise and training sessions. Vi will say things that help you get to your goal, motivate you, and push you beyond your goals.

Vi will start giving you fitness plans that align with your goals. But instead of robotically forcing you to those goals and ignoring you if you don’t complete them, Vi will take a more customized approach. She’ll be understanding when you miss your daily 5K run, for example, and will adapt your training routine to that miss.

All of this information is delivered through a female voice. LifeBeam actually tested 100 voice actresses before settling on one with an “amazing voice”. They aimed to find a voice that was compelling, warm, and welcoming. Some people have compared it to the AI from the movie Her.

Here’s an example of how Vi can work: if Vi knows your goal is to burn fat, then she’ll tell you to pace up and down with your exercise to get you within the optimal heart rate zone for fat burning.

Then, she’ll take into account things like environmental sensors, temperature, location, elevation, and heart rate. She can also notice if you’re fatigued from training, in which case she might ask if you want to slow down a bit.

You can also setup Vi to communicate via text message. In one promotional image posted by LifeBeam, Vi was seen messaging someone:

“Hey Jess! Looks like it’s going to rain today :(. You down to train indoors instead?”

There’s even an emoji in the message! Other texts say things like “Tomorrow, we train for your 5K. You ready for it?”
