I love it, this is a very cool product! I'm a runner and I know what it means to have a very uncomfortable earpiece that makes your running miserable and I also know what it means not to have your music to motivate you get through the hard parts of the running.
As the video says, this is exactly what runners need as it's wireless and safe because it doesn't isolate the outside noise, you can still hear cars coming and you can a avoid getting hurt.
I don't know about the price, I saw you can have it for $100 which can be nothing for some and a fortune for others but it's still amazing to have such a product!
Nice hunt!
