It's not enough to know OPPO's smartphones. In the field of audio-visual equipment, OPPO not only has a Blu-ray player, which is known as a "palace-level all-round player" in the European and American markets, but also the highly acclaimed OPPO PM-3 headphones. Not only did it get the first recommendation in The Wirecutter's "Best Over-Ear Headphones Under $400," but it also scored 86 points in the U.S. Consumer Reports, tied for third place. The exterior design of the PM-3 is very similar to that of the HIFIMAN HE-400i, but with the "Spiral Booster Planar Diaphragm Technology", the weight is reduced by 20% and it is highly portable. Still, the sound quality is impressive, and Consumer Reports makes a point of noting that if you're a fan of top-notch music and movie soundtracks, the PM-3 is just what you're looking for. The price is 2698 yuan, and there are black and white options.
