Yes, but these are the only headphones I have that need
any EQing, other than just boosting the bass. I don't think anybody has ever referred to the HD 650 as bright, but in comparison to the PM-3 they are... At least to my ears. And compared to my DT 1990, the bass is absolutely rolled off.
Here's how I'd say they compare to my other phones:
vs DT 1990: (DT 1990 cost 50% more) PM-3's sub-bass is rolled off, lacks "slam;" mids are less pronounced; treble is way, way less present (DT 1990 are known for bright treble, so no surprise)
vs HD 650: PM-3 have similar sub-bass extension, but less mid-bass emphasis; mids are significantly less pronounced; treble is less present
vs qJAYS v1 (PM-3 are almost 100% more expensive): PM-3 have less bass extension, though there's more of the bass that it does have; mids are less pronounced; treble is significantly less present.
vs RHA T20i (PM-3 are 100% more expensive): PM-3 have less bass extension and less bass overall; mids are less pronounced; treble is less-to-significantly-less present.
DT-1990 are considered bright but otherwise neutral, HD 650 are considered dark and warm, qJAYS are considered neutral but bass shy (it's what was called "flat" when describing IEMs some 10 years ago), and the T20i are generally considered to be v-shaped-- and yet the PM-3 are the
only ones that need EQing! I just can't understand how that could be considered either "neutral" or "transparent."
And as to their being "sharp like scalpel..." My impression couldn't be further from this. The DT 1990, is sharp and surgical. The PM-3 is not."
I am trying to find headband cover for the oppo pm-3. Will the dimensions of any of the above headphones match the PM3?
The only cover I noticed which might suit its dimensions is :
https://www.amazon.com/dp/B078MFY3X...colid=Z400Q1VIIYWS&psc=0&ref_=lv_ov_lig_dp_it
24cm long and 10.5 cm wide . its made of wool yarn.
The headband cover is flaking off. I was nervous that the same thing might happen to the earpads. I changed the earpads to brainwavz angled sheepskin earpads. I feel that the sound is much better , especially bass. It appears that the default earpads might be suppressing the signature of the oppo pm -3. I feel there is more depth, little more soundstage, little more details and decent bass.
This is my first decent headphones . Had bose in ear phones and a sony headphones which I got for 40 USD .
You might want to try the earpads.
Thanks all.
