The Oppo PM-3 are well-designed, mobile-friendly, planar magnetic headphones. They're comfortable and have a good, crisp sound quality. However, their closed back design, is not the best for critical listening. They also don't block much ambient noise and will struggle a little on noisy commutes.
- Above-average audio reproduction.
- Sturdy, well-built design.
- Poor noise isolation
- Slightly heavy and cumbersome.
The Oppo PM-3 are well-crafted headphones. They look sleek and stylish and make use of sturdy, premium materials in their build. They comfortably fit around most ears, and they're not too tight on the head. However, they're a little heavy for their size, they don't fold into a more compact format to carry around, and they're not the most stable headphones. They will slip off your ears if used while running or exercising.
The Oppo PM-3 have a simple design that looks great and feels high-end. They come in three color schemes; Black, white and the two-tone steel blue option of the unit reviewed. They stand out in a crowd, yet are not as flashy as some other over-ear headphones. They also make use of a lot of metal and premium materials in their build, which further adds to their high-end appeal.
The Oppo PM-3 are a little heavy but comfortable headphones. They don't apply too much pressure to your head. The ear cups are well padded and sufficiently large for most listeners ears. The headband is also equally well-cushioned making for a very comfortable listening experience.
The PM-3 are not sports headphones. They're a little bulky and slightly heavy for their size. That combined with their lack of tightness, makes them prone to slipping off your ears when used during exercise or running. On the upside, they easily stay in place during casual listening sessions and also come with a detachable cable that will disconnect if hooked on something rather than yanking the headphones of your head.
The Oppo PM-3 are mid-sized over-ear headphones. The ear cups lay flat to take less space, making the PM-3 somewhat portable. Unfortunately, they don't fold into a more compact format and will take a decent amount of space in a backpack. They're a little cumbersome to carry on your person and won't comfortably fit into smaller bags.
The PM-3 come with a durable hard case covered in a denim fabric that will protect your headphones from minor falls and water damage. It adds a bit of bulk to the headphones but easily transports all the provided headphone accessories.
These headphones are well built. The frame and joints of the headband are made of metal and feel sturdy and durable. The ear cups are dense enough to handle a couple of drops without breaking. The cable is thick and rubberized and won't get damaged quickly by wear and tear. The swivel mechanism may eventually loosen over time but isn't something to be too worried about.
The Oppo PM-3 have a good audio reproduction but a poor soundstage because of their closed back design. They have planar magnetic drivers that can still be powered by your mobile device and delivers a punchy bass, balanced mid-range but slightly overemphasized treble. This results in a tight bass and clear representation of instruments and vocals. Sadly, they can sound a little sharp with some tracks.
Very good Bass Range performance. Although low-bass is extended down to 17Hz, it is underemphasized by about 3dB, negatively affecting the thump and low-rumble. High-bass is hyped by about 2dB, adding excess warmth and muddiness to the sound.
Excellent Mid Range performance. The response is flat within 2dB of the target response, but we had difficulty matching the L/R responses. The mismatch in the response is subtle enough to be inaudible to most, yet, it still affects the Imaging score.
Average Treble Range performance. Low-treble is well-reproduced, although the 4dB dip surrounding 5KHz could negatively affect the clarity and detail of leads/vocals. The bump in treble makes these headphones noticeably sibilant, which could sound too sharp to some. The 15dB peak at 9KHz, although quite noticeable, won't sound as loud as it looks, due to its narrow width.

Poor soundstage. Due to the shallow enclosure and small ear cups, these headphones don't activate the resonances of the ear the way a loudspeaker does. Therefore, the soundstage could be perceived inside the listener's head, as opposed to in front. Also, because of their closed design, they don't merge the music with the outside ambience and sound isolating and closed.
Decent Imaging. Very low amounts of phase error were produced by these headphones, especially in the Bass Range. The drivers of our test unit were quite well-matched in terms of amplitude and phase. Unfortunately, the frequency response was significantly mismatched. This seems to be a downside of Planar Magnetic headphones as it is more difficult to keep a low manufacturing tolerance.
Excellent harmonic distortion performance. The response looks quite jagged, which seems to be typical of Planar Magnetic headphones. However, the more narrow-band spikes won't be audible to most. The amount of harmonic distortion at 90dB SPL is quite good, though, there is a noticeable rise in the amount of harmonic distortion at higher volumes.
The PM-3 are not active noise isolating headphones. They will block some ambient, high-frequency noise thanks to the good seal they create around your ears. Sadly, you will still be able to hear the train or bus on a busy commute and the people around you in a loud office. On the upside, they don't leak too much and won't be distracting at moderate volumes.
Poor isolation. These headphones don't have active noise cancelling and there's virtually no isolation provided in the Bass Range. However, these closed-back headphones are able to achieve a total of 11dB and 39dB of reduction in the Mid and Treble Ranges respectively. Both values being quite decent.
Decent leakage performance. The majority of leakage is in the 500Hz-2KHz frequency range, which is a relatively narrow band. Additionally, the overall level of the sound that escapes the headphones is relatively low too.
No active features.
