Occasionally, we long for simpler times -- times when "handsfree" meant little more than connecting a corded earbud to your phone and calling it good. Nowadays, of course, things are a little different: Bluetooth is quite literally everywhere, headsets have their own frickin' apps, and bone conduction tech is the real deal. Take this Sound ID 510, for example, featuring its very own iPhone app (which Sound ID made sure to get approved by Apple ahead of the actual hardware's release) that lets you control a number of settings, check your battery level, and find the set if you misplace it. To be fair, it's not the first time we've seen an on-phone companion app for a Bluetooth earbud, and something tells us it won't be the last; that's right, welcome to our frightening new reality. Look for the 510 to hit shops in early June for about $130.
