1. The speakers aren't Bang and Olufsen - they are standard generic parts; it's "audio by B&O" - i.e. they provided some graphic equalizer settings. Misleading, yes, and HP deserve to be called out on this.
2. The USB type-C is only 3.0, not 3.1 as stated. You can't use it for charging, displayport, or thunderbolt like you can on the Dell XPS.
