Couple of early impressions are in. Andrew Martonik Android Central "The core feature of this design is comfort — these are easily the most comfortable wireless "earbuds" I've ever placed in my ear." "the Pixel Buds have almost no sound isolation. Because there's no rubber "tip" that goes into your ear to seal out the outside world, you still hear most everything around you." "The case looks nice. The fabric on the outside and soft rubber on the inside are very friendly and easy to get acquainted with. But I have serious concerns about the longterm durability of something that is this soft." "Though these aren't the only proper "Google Assistant headphones," this is my first experience with the feature — and consider me super impressed. Rather than using "OK, Google" detection, the Pixel Buds trigger Assistant by pressing and holding on the right earbud (yes, only the right one) to speak the command. Lift off of the earbud, and it finishes taking your input and does what you asked it to do." Dieter Bohn just did a quick first use video on his facebook page as well. So far, really good reviews. I ordered some but they won't come until about Christmas.
