For anyone interested in my first impressions of the newly arrived Pixel Buds, I posted my comment just now to the Pixel Bud headphone comment section in the same Mobile Phone section you are currently in.
First impressions: very positive. The sound quality is excellent. The fit in the ear is really snug. The Google Assistant feature works really well with Bluetooth. The set up and Pairing process was a breeze. The Google Translate feature with the language translated returning back through the Pixel Buds is amazing. The notifications work well, which you can switch on and off if you want to skip them. The touch control features are intuitive.
Happy to answer any questions. I see them as an excellent £ 159 stocking-stuffer and plan to get a Black Pixel Bud for a family member.
Seems the opposite of every review I've read. Feel free to put them in my stocking though. I can't see many splashing out £159 for those ear buds.
