So here's another project that is kind of relevant to smartwatches/smart bands: https://www.kickstarter.com/projects...your-fingertip I'm looking forward to using this along with my Pebble Time. I don't listen to music much and so having cables or hands free bluetooth things stuck in my ears isn't appealing, but this is really cool. Also, you are able to block out background noise at the same time as hearing a call, which is great.
