Tiny little wireless, water resistant earbuds that cancel noise, play music, let you make calls, and bug Google Assistant or Alexa with all your questions. Sony's wireless earbuds look cool and comes with a "high-friction rubber surface" that's supposed to keep them snug in your ear, even if that feature sounds kinda funny. Sony, can we please talk for a minute about how you've developed the world's most confusing naming system for your headphone though? Because, really, what is up with that?

What could happen if something goes wrong?

We couldn't find too much that could go wrong with Sony’s headphones. We suppose you might go and try to read their privacy policy, get lulled into boredom by the complex, legal language and fall asleep with the volume on your headphones up way too loud, causing hearing loss. Don't listen to your music so loud when reading privacy policies! And Sony, please make your privacy information more accessible to consumers.

Sony does say it may use or share de-identified personal data for advertising purposes. This is generally OK, although many privacy researchers will point out it is relatively easy to de-anonymize such data. Also, if you choose to use Amazon Alexa or Google Assistant with this smart speaker, know that Google and Amazon will collect data on the voice requests you make.

Tips to protect yourself

  • Consider setting up a password for Bluetooth pairing
  • Consider using your headphones without connecting it to an app. This way, you may decrease amount of data collected
