OPPO PM-3 Impressions
Been listening to the PM3 for quite a bit. This does require adequate power but most portable players can handle it. I personally can't get past 75% volume on the iPod touch 5gen and 80clicks on the FiiO X3 2nd gen.
BASS: Layered, textured, detailed, decay is just right (not fast, not slow), excellent timbre. Quantity is perfect for me, just a slight bump over flat. Sub bass extension is great with good rumble. Not as strong as M100 tho...
MIDS: I'm quite surprised it's NOT mid-centric. Vocals is not upfront, it sits just a bit behind the instruments. Excellent detail, imaging, and separation. If you love different instruments, this is the headphone for you. I don't see this becoming a favourite for VOCAL lovers. Don't get me wrong, vocals sound really good, both male and female. But the presentation is not focused on Vocals. It's more about what goes on around the vocals, and the PM3 does it very well.
TREBLE: excellent timbre and decay. cymbals sound realistic. can be a bit sibilant (SSSSS's) with some tracks but if you find the right placement of the ear cups, this is minimised.. Placement of ear cups is crucial. Not that hard to do, which is good news. Extension is not perfect; lacks a bit of air to be honest. But the detail is there, its not completely gone, just recessed from the rest of the frequency.
SOUNDSTAGE: Not wide, but good enough to keep the sound out of your head. 3D image is good, I'd say that the width, height, and depth are proportional. So an excellent projection considering this is a closed headphone.
The PM3 sound is not inviting; it doesn't sound special either. It took me an hour of audition before I was convinced. It's a laid back presentation but doesn't give up on detail, imaging, separation, and clarity. And that what convinced me to get them.
CONS:
- crap, apple-like cable - the one with mic/remote which you have to buy separately. I did not buy it. (thank God the longer straight cable is good quality)
- Lacks a bit of air (easily fixed with EQ - +4 @ 16khz on X3 2G)
- ear cups can be a bit small for large ears. (I've got small ears so I'm good.)
