The thing to know about these bad boys is that they sound musical. For a closed back headphone, they have a pretty decent soundstage. They sound like you’re right there in a live setting, and really excel with instruments and vocals especially.
They’re unique in the fact that they are a planar magnetic headphone, but closed back and significantly lighter than say a HIFIMAN or Audeze model.
Captures vocals and instruments very well. Great mid-range.
Natural bass. Balanced, refined, and nice and tight. 😉
Big heads need not apply. If you have big Ross Perot ears, you may be in for a world of pain like Smokey from Big Lebowski. Lol. The elongated ear cups may cause discomfort depending on the size of your melon.
High end not as crisp as some cheaper phones. A tad subdued.
Could have benefited from deeper ear pads. Your ears may touch the driver assembly causing some minor discomfort.
Because the ear pads are made of synthetic leather, they may become warm and sweaty after prolonged wear.

These will require an amp to reach their full potential. The Oppo HA-2 gets really good reviews and should be your go to amp if you end up purchasing these. You will be blown away.
If you really want to be blown away though, like 3 little pigs style, then the Oppo HA-1 Headphone amplifier is the cream of the crop here.
Know that instruments and vocals will be the highlights of this can.
Not quite as good for:
Thought’s from Stu’s notepad
Not for bass heads.
Getting a good fit is of the utmost importance.
The headphones come with a 3m cable terminated with stereo mini plugs on both ends. The adapter it comes with can be plugged into a standard headphone jack. Lastly, you are also supplied with your choice of 1 meter cables; either an iPhone compatible, Android compatible, or plain cable. The cable plugs into the bottom of the left ear cup.
Comes in a drawstring bag. The case is made of soft denim and semi-rigid. It will fit the headphones as well as all of your cables.
Can be converted to balanced mode by changing cables. An example is that you could purchase separate cables which improve transparency and make the headphones sound even better. Surf cables are what they’re called.
Old recordings will reveal details you haven’t heard before.
Minor details in the music will be pushed to the forefront, allowing you to experience them in all their glory.
Replacement ear pads can only be purchased from Oppo.
A ruggedly built and neutral set of headphones with a slightly problematic treble range. Great mid-range and textured bass response. Comfort is a mixed bag depending on the user.
Similarities & Differences
Both are closed back with a phenomenal build.
Both ear cups tend to get hot with extended usage.
Both use detachable cables that plug into one side.
Both sound fine with a portable device but do benefit from a good Amp/DAC.
Both have quality packaging and care.
Overall sound. The PM3’s come across as cleaner and more precise, with less distortion than the P7’s. The PM3’s are warmer and clearer. They have a more colored sound than the PM3’s.
Vocals. Voices can be slightly thin lacking the warm lower tones and not nearly as present as the P7’s.
Mid-range. The mid-range on the P7’s is more recessed, meaning lacking or distant. While vocals can come across as thin at times with the P7, they really stand out as being a prominent feature with the PM3’s.
The PM3’s are neutral across the board, with nothing overpowering another.
Treble. The treble on the P7 is much brighter with more resolving detail, while the treble on the PM3 has been called subdued and dare I say “dull.” It’s definitely a point of contention and the most talked about aspect of the PM3. There’s more body and more “air” with the P7’s treble. If you’re looking for texture, and a more neutral, smoother treble, the PM3 is your boy. If you’re looking for a brighter, crisper high end, the P7 is where it’s at.
Isolation. The P7 isolates sound better than the PM3.
Genre. PM3 may be pickier with genre, while the P7 is more diverse.
Source. The P7 is more forgiving with your audio source, and leans towards a more mainstream tonality.
Material. The P7’s ear cups are made of lambskin leather while the PM3’s are synthetic (protein) leather.
Cables. The cables on the P7’s are proprietary (meaning you can only use Bowers & Wilkins cables), while the PM3’s are universal.
Weight. The PM3’s are heavier than the P7’s and have a stronger clamp force. The PM3’s also have wider ear cups and a more comfortable head band.
Ear cups. The ear-cups on the PM3’s are more shallow than the P7’s.
Comfort. Overall, the PM3’s are more comfortable.
Bass. The bass on the PM3 is more nuanced, textured, and detailed, while the P7’s bass has that immediate impact and punch. In complex arrangements, the P7 may suffer by becoming a bit muddy or boomy.
I don’t really like the sound signature of the P7, and wouldn’t recommend it though it’s build quality is superb. I absolutely love the PM3 though.
If you’re after a flatter, more neutral sound, the PM3’s fit the bill phenomenally well. They are lighter on the bass, but it’s more textured and detailed. The treble is dull in comparison to the P7, but it’s smoother and also slightly more textured.
