I've owned a couple dozen headphones, just like probably anybody in these threads reading. Nothing terribly expensive - maybe $300 cap.
The universally highest acclaimed headphones I've owned were HD600 and HD650, both since sold. I've owned and tried Grado, Denon, multiple Sennheisers (which I generally like), Sony, etc, etc etc. To my ears these Philips X2HR are my personal favorite so far, that I've owned - that won't change because of a review. I made my personal preference decision doing A/B listening without consulting a review. I hate to see some people in this thread say, 'darn, these were my favorite headphones, until this review.' You like em before the review? You'll still enjoy listening to them after the review. Right?
Relatively easy to drive, super comfortable with the oversized pads and internal cup size - they don't touch my ears at all, standard jack so you can use any cord you want or add a V-Moda mic for headset use, they sound great to me with nice feel good bass, and a nice big soundstage (for headphones), and at the $100-$120 price point they have a really high quality build, look and feel --> better than almost anything else I've owned.
I don't EQ them, I like them just the way they are.
When I bought them I sold my Sennheiser HD-6XX (HD-650 equivalent) shortly after because I preferred the X2HR in my A/B testing. Since then, for about the last year, the X2HR have been my daily driver for PC gaming use. I personally preferred or found equitable almost everything about my X2HR over the HD-6XX bullet by bullet so have no reservations on selling the HD-6XX. To each his own I guess. I've not found them harsh, personally, but I don't really do critical listening with them. I just enjoy them for what they are very comfortable gaming headphone/headset that I think sounds great. I'm not challenging the objective measurements, just perhaps encouraging a potentially interested party to not dismiss them outright. Perhaps you may, subjectively enjoy them quite a bit - if not - they are easy to resell and try something else. To the guy who said they had SHP9500, liked them, and had considered upgrading to these before this review. I say still do it. The X2HR are a small nudge better than the SHP9500 is almost every way and I too like my SHP9500 (I still have). Sound between the two is certainly similar - a bit better bass and comfort on the X2HR when I compare them side by side.
