While certainly not the most expensive headphones on the market, Oppo’s $699 PM-2 planar magnetic headphones still represent a significant financial investment. If you’ve been saving your dollars in the hopes of one day finding a killer pair of headphones, that day is here: Oppo’s PM-2 will endlessly engage you, beautifully unwrapping the hidden nuances of your musical collection one layer at a time. There aren’t many no-brainers in life. The Oppo PM-2 is one of them. Very highly recommended.
