What OPPO has done in making a planar as efficient as some of my IEMs is nothing short of amazing, but OPPO seems to actually listen to people, so please, just fix these the treble and bass problems (and maybe a little more midrange and air) and you’d have a headphone that rivals the best Audeze and other warm-sound-favored companies have to offer. But that extra stuff would likely result in a headphone that costs much more than the PM2. $699 is a lot of money for a headphone, and I never like recommending people buy anything that costs more than $300, but I can’t think of a better “buy one, use forever” highish-end headphone than the PM2. The magic with these headphones isn’t that will “wow” you at first listen, but that it allows one to ease into its sound and consistently sounds at least decent no matter where they are used, be it a cell phone or a megabuck amplifier. That’s more than I can say about most headphones.

    Hi Kyle,

    Would this be a good step up from the Grado SR225e? I love my Grados, I’ve owned a NAD Viso HP50 in the past which sounded dull and lifeless. I would like to upgrade to a planar but just want to avoid anything that sounds like the NADs. Thanks for the great review.

      I think Kyle missed this one, Grado;s have a lot of energy, the PM series for me has similar energy but not as fast for the pm-2, the pm-3 might be a wiser choice or the HE400S from Hifiman

      This is going to sound like a cop out, but I don’t really know how to answer that because they sound completely different. The PM2 fits my tastes better, but I don’t know what your tastes are. Objectively, the HD700 might have more detail and harder hitting bass, but its treble can be incredibly annoying if you don’t tame it whereas the PM2 has more forward mids but isn’t all that resolving/sounds kind of fuzzy. I honestly prefer the HD600 to both of these in most situations because it sounds more natural in all but the bass, which is kind of loose.

        I own the hd650, I like it, I just want more detail, sometimes I feel like I am missing something because of the dark and thick sound of the hd650. Is the hd700 the right upgrade?
