Oppo PM-3 Review: Features, Sound Quality, and Build Overview
The Oppo PM-3 is a closed-back, over-ear headphone that utilizes planar magnetic driver technology, which is often reserved for larger, more expensive home-audio models. Its main purpose is to deliver a high-resolution audio experience in a portable form factor that can be effectively driven by smartphones and portable music players, without requiring a bulky external amplifier. This makes them incredibly versatile for both home and on-the-go use.
This product is designed for a specific audience: the discerning listener who refuses to compromise on sound quality but needs the practicality of a closed-back design. Whether you are a music producer looking for accurate monitors for tracking, an audiophile commuting to work, or a frequent traveler who wants to escape into a rich sonic world, the PM-3 aims to satisfy. Key specifications include its low impedance and high sensitivity, making it easy to drive, and its use of rare-earth magnets and a seven-layer diaphragm for the drivers, which contributes to their fast and detailed sound character.

Key Features & Performance
During my testing, several key features of the Oppo PM-3 consistently stood out, contributing directly to its impressive performance. The marriage of its core technologies with a user-friendly design is where these headphones truly shine.
Planar Magnetic Drivers
The heart of the PM-3’s performance lies in its planar magnetic drivers. Unlike the more common dynamic drivers found in most headphones, planar magnetic technology uses a thin, flat diaphragm with an embedded circuit, suspended between powerful arrays of magnets. This design results in several audible benefits. I noticed an exceptionally fast transient response, meaning notes start and stop with incredible precision. The bass is tight, deep, and completely free of the bloated or “one-note” character that can plague some closed-back designs. The level of detail retrieval across the entire frequency spectrum is simply outstanding, allowing you to hear subtle nuances in your music that lesser headphones might gloss over.
Build Quality and Materials
Picking up the PM-3, you immediately sense its quality. The construction is a mix of a magnesium alloy frame and soft, memory foam earpads covered in premium synthetic leather. This choice of materials makes them remarkably sturdy yet surprisingly lightweight. The headband has just the right amount of clamp force, and the yokes adjust smoothly. I found them to be exceptionally comfortable for multi-hour listening sessions, with the plush earpads creating a good seal that aids in both comfort and noise isolation. The overall feel is one of a product built to last, without being overly heavy or cumbersome.
Portability and Accessories
Oppo clearly designed the PM-3 with mobility in mind. They fold flat into a very compact form factor, and the included hard carrying case is not just an afterthought—it’s a robust, zippered case that provides excellent protection in a backpack or luggage. The package includes two detachable cables: a standard straight cable and a coiled cable, both of high quality with minimal microphonics (the sound of the cable rubbing against itself or your clothes). Having these options is a thoughtful touch that enhances the overall user experience, whether you are at a desk or moving around.
Sound Signature and Isolation
The sound signature of the PM-3 is best described as neutral and balanced with a slight touch of warmth. It is not a “fun” or V-shaped sound that artificially boosts bass and treble; instead, it presents music in a very accurate and uncolored way. This makes them excellent for critical listening and professional applications. The closed-back design provides very effective passive noise isolation, effectively blocking out a significant amount of ambient noise from your environment. This allows you to focus on the music without needing to crank up the volume, which is a major benefit for both sound quality and hearing health.

Final Verdict
After a thorough evaluation, the Oppo PM-3 leaves a strong and positive impression. It successfully carves out a niche for itself by offering a rare combination of reference-level sound, practical portability, and exceptional build quality. For anyone in the market for a closed-back headphone that prioritizes sonic accuracy above all else, the PM-3 is an easy model to recommend.
Pros
- The planar magnetic drivers deliver a clean, detailed, and well-extended bass response that is both impactful and controlled.
- The neutral-warm sound signature is non-fatiguing and highly accurate, ideal for mixing and analytical listening.
- Superior construction with premium materials that feel durable and look sophisticated.
- Excellent included accessories, including a practical hard case and multiple cables, add significant value.
- Effective noise isolation makes them suitable for use in noisy environments like offices and during travel.
Cons
- The intimate soundstage might not satisfy listeners who prefer the vast, open feeling of high-end open-back headphones.
- Those with larger ears might find the circumaural (over-ear) fit to be a bit on the snug side.
- While easy to drive, they do scale well with better amplification, which could lead to an additional investment for some users.
I would recommend the Oppo PM-3 primarily to audiophiles, audio engineers, and dedicated music lovers who need a single pair of headphones that can perform flawlessly both at home and on the move. However, if your primary desire is for a wide, spacious soundstage for classical or live music, or if you have a strong preference for a bass-heavy sound signature, you might want to consider other options.
