Just put up my review: http://www.head-fi.org/products/audio-zenith-pmx2-headphone/reviews/13463
* edit 06/30/15 - This review seems to have gotten buried along with all the other reviews in the "Head Gear" section, so I've cut/pasted to the main impressions thread for easier reading.
TL;DR - Overall score of 9/10. Nearly perfect reference level headphone.
Pros: Flat and exciting signature. Silky smooth treble & amazing mids. TOTL quality sound, looks, and comfort.
Cons: Expensive, Non-removable ear pads, One man company... so long term support is an unknown, could use a little more sub-bass (imo)
Audio Zenith PMx2 Over-ear Planar Magnetic Headphone:
*Disclaimer - I am in no way affiliated with Audio Zenith, Oppo Digital, or any public headphone/electronic company. I’m just an amateur enthusiast who works a normal 9 to 5 office job in the import/export field. I usually listen to headphones on average of 2-4 hours per day. My preference is towards slightly warm headphones, with an emphasis on the mids. I was introduced to these headphones at THE Show in Newport 2015, and paid full retail for them directly through Audio Zenith’s website:

Audio Zenith Background:
Founded in late 2014
, San Diego, CA based Audio Zenith is a budding headphone modification company which focuses its efforts exclusively on modifying the Oppo PM-2 planar magnetic headphone. While his company has only been around for a little over six months, owner Alex Zaets has been tinkering with Oppo’s planar magnetic headphones for quite some time, as a result of his relationship with Oppo’s lead headphone designer Igor Levitski1. He has been tinkering even longer in the realm of digital signal processing, and previously attended high-end audio shows under the company name of “Acoustic Zen/Million Dollar Sound” to show off his dsp work with. TAS reviewer Robert Greene even went as far as to say, “[Alex's system] was gorgeous, to my ears some of the most beautiful and musically truthful sound at that or any other show. And indeed [he] got the room really out of the system to a startling extent.”3
Audio Zenith is the first officially sanctioned aftermarket dealer of modified Oppo headphones. Being a small startup, current production is limited to only a handful of modified PMx2’s per month, and all are modified/tuned to order. Please contact Audio Zenith for lead times, as they may change based on demand.
PMx2 Introduction:
Pronounced “PM times 2”, the PMx2 headphone is a result of over two years of work, and more than two thousand measurements in an effort to achieve, what Alex considers to be, the perfect reference level sound signature. From fine-tuning the drivers to developing five different zones of pad density, it’s safe to say that developing the PMx2 was a massive labor of love on his part. After spending a few days with the end result, I think it’s also safe to say that his efforts have paid off quite nicely.
Specifications:
The PMx2 shares the same specifications as the stock PM-2.
