User Review: General Thoughts: Coming from the Philips X2 this headphone was full of surprises! First of all I could not detect this veil people were talking about. On various forums these can's were described as being recessed sounding; Like you were sitting in the back row at a concert. To me they were the opposite! Everything sounded very clear and crisp to my ears and I felt as though I was on stage with the musicians. These headphones were also characterized as being boring but I found that I can rock out with them! I was also surprised at how easy they were to drive. I have an O2 amp/ODAC and I rarely had to engage the high gain mode to get my desired volume. Very cool.

Sound: The midrange is definitely the highlight of these cans. They are in your face and will immediately grab you and pull you in! Both male and female vocals sound very good on these. If you prefer a more intimate midrange then these are the headphones for you! Bass is a bit light but not as bad as I was expecting. Still I would prefer a bit more as everything sounds somewhat thin. The treble was another surprise as I found them to be a little too shouty for my tastes; specifically in the upper midrange to lower treble. Then again I have pretty sensitive hearing so this may not be a problem for others. The sound was very clear and not lacking in energy. The soundstage though was almost practically missing! There was never a moment when a voice seemed to be shouting from across the room or from behind.

Comfort: The comfort was good but not great. There's definitely a clamp on these. They do get a little annoying after awhile but then again I have a big head so YMMV here. The X2's on the other hand almost disappear on my noggin'. They are easily the most comfortable headphones I've ever worn.

Build Quality: Somewhat lacking. It feels like the plastic on the headband will crack under slightest amount of pressure. They feel very cheap to me. These headphones do not seem to be built to last and I could see myself breaking them within a few years even though I'm very careful with my possessions. If they were to fall on tile or a hardwood floor then I could see them breaking or cracking easily. The X2's on the other hand are built like a tank! You'd have to run over those with a car to damage them!

Conclusion: All in all these are very nice headphones. They have a reputation of being the gold standard for headphones and though I feel that's somewhat justified I still prefer my X2's. If you get the HD600's then I think you'll be pleased with them. They sound very natural but do lack a bit of the fun factor of the X2's. If you like to analyze your music or do any kind of mixing then these should definitely be on your short list! If it wasn't for the X2's then these might be my go to headphones despite their shortcomings.

Update (2/6/16):

Well it seems that my X2's bit the dust. I barely had them for 6 months when the right side driver blew. I returned them to Philips for a full refund as I was within warranty however the new version I procured sounded very little like the original. Bigger but less controlled bass, very little treble to speak of, and an even more distant midrange! Needless to say I returned them to Amazon as soon as I could! Thanks for ruining an excellent headphone Gibson!  I liked the HD600's a lot due to the naturalness of their tone but I didn't care for their somewhat lacking bass and their annoying upper mids. So I decided to give the HD650's a try considering they were very similar in tone and I was totally blown away! They had all the things I loved about the HD600's but with more bass and none of the peaky upper mids! They also have a larger soundstage though not as large as the X2's. The midrange is to die for and these are now my go to headphones for rock! Even electronic music sounds very good on them. So if you're like me and enjoy some bass with your music but still want beautiful mids then give the HD650's a try. You'll be glad you did!
