Wearables are now part of everyday life. Many people now wear a smartwatch as a matter of course, count their steps, monitor the quality of their sleep or set reminders to take breaks during the day. And I'm happy to admit it: I also have a Apple Watch myself, and I find this technology absolutely fascinating in its own way. It can do things that would have been pure dreams of the future just a few years ago. Nevertheless, I rarely use my Apple Watch.
And just now, after the latest reports and statements from experts, I realize once again that this reticence is not so wrong. After all, many modern headphones and wearables now contain sensors that can measure far more than you might think at first glance. Not all headphones do - but the trend is clear: more and more technology is moving inconspicuously into small devices that we wear close to our bodies.
