Denon AH-MM400 (2016) vs Bang & Olufsen Beoplay H4 (2017)

The Denon AH-MM400 (2016) is a relatively good Closed-Back Headphone for people that are willing to spend around $340. The Bang & Olufsen Beoplay H4 (2017), by contrast, is quite unremarkable and doesn't stand out in any meaningful way from other products at this price point.
