I've used Bose's QC Ultra Headphones for hundreds of hours, but is the cheaper QC Headphones 2 a better buy? I've tested both side by side

Bose QC Ultra Headphones versus base QC Headphones 2.

Recently, Bose launched the QuietComfort Headphones (2nd Gen) – sometimes abbreviated as 'QC Headphones 2' or, per the app, 'QC 2 HP' – and I've been using them for a full week.

However, over the years I've used the original Bose QuietComfort Ultra Headphones for hundreds of hours since their launch.
