They were revealed yesterday at an event in San Francisco, where Google also unveiled its new Pixel 2 phone, an update to the Google Home device.
According to Google, the Pixel Buds can translate 40 languages using Google's existing Google Translate technology. You just need to hold the right earbud and say, for example, “help me speak French”. When you next speak, the Buds will then play the translation out loud in French. If someone speaks to you in French, the Buds will play you the translation in your ear.
This might sound like magic, but Google Translate is already pretty well established .
They will retail for just $159. They’ll start going on sale in November – and might just change the world.
