Google finally started shipping the second-generation Pixel Buds, and with them came a slew of new features for Android's Bluetooth stack. The 2nd-gen Pixel Buds are Google's first truly wireless headphones, and they are finally on sale for $179 in the US. They were announced a whopping six months ago at Google's annual hardware event, alongside the Pixel 4, Pixelbook Go, and Nest Wi-Fi. They have an always-on Google Assistant, a charging case, and no active noise cancellation.
