One of our chief complaints in our hands on Google Pixel Buds review was that the "wireless" earbuds aren't actually wireless.

That's because the headphones, which tout the ability to translate different languages in real-time, are connected by a cord, thus disqualifying them from being true wireless 'buds, as is the case with the Apple AirPods or Samsung Gear IconX.
