But I wonder if the features that were selling points are even possible to pull off. Specifically is it possible for, "music that played through the earphones was supposed to change in pace and volume as the user's heart raced during a workout. Users would be able to control how much ambient sound the earphones let in -- listeners would be able to block out the outside world, or set the earphones to let them hear oncoming traffic while biking or walking."
The video reviews on YouTube said these earbuds were a disaster and I understand that. But I figured you DIYers would know if this is even possible to make happen in the first place.

I'm not a scientist or music engineer, but that "sounds" impossible. Pun intended. Critical thinking skills will tell you that your heart beat cannot change the pace or volume of sound waves. Especially if the point of origin of the music is outside of your body.
I was surprised that so many people bought into it because it sounds like an impossible feat for one product to pull off. I didn't think the technology existed to make it possible and it doesn't sound like something that can be created in the future either.
