I’ve seen and reviewed a lot of wireless earbuds in the past, and the most “convenient” ones are like the Jabra Sport Wireless, which are two earbuds that are joined together by a singular wire. While I was at CES 2015, I saw two pairs of completely wireless earbuds that snip the wire and keep the sound.

I’ll start with the Dash, from a company known as Bragi. The Dash is a “Hearable” which I am assume is a combination of “hear” and “wearable”. So, as a wearable, it has body sensors that can actually track your performance as you are running in real-time. Stuff that can be tracked is pace, steps, cadence, distance, heart rate, oxygen saturation, and energy spent.

What is interesting is that you don’t have to be hooked to a phone in order to listen to music. That’s right, it has 4 GB inside that you can play 1000 songs with. Not bad. By the way, it can drown out almost any outside sound.

Now, if you want to pre-order it, you can for a price of $299.00, and it should be available in April right here.

The second product that are Totally Wireless Earbuds is the Free Wavz. These have 3-axis accelerometers and pulse oximeters that can monitor heart rate, calories burned, speed, distance, workout duration, and oxygen saturation.

As you can see, the Free Wavz has a different look than the Dash. They have internal Flash memory with 16MB, which isn’t as much as the Dash, but I am not certain if you can operate the Free Wavz without a phone.

I believe that the Free Wavz will be available sometime in March 2015 right here.
