These Sonys blew me away! I compared them side by side with the with the previous benchmark in ANC headphones, the Bose QC35 IIs: - in terms of noise cancelling, these are on par or better. I wear these at work, or at home while my wife watches TV (or when she's around generally), and they work great. - for music, these flat out are in a different league to Bose. The bass is deeper, the sound stage is wider and the vocals are crisper. With the latest update, also now supports Alexa. So with the better tech and longer battery life, it's a no brainer. Amazing headphones.
