Okay so I've had some time for my ears to get accustomed to the way the HE4XX sounds and then I went ahead and switched back to my HD 650 and wow. I never realized how weak the HD650's upper end extension is until now. Also, the HE4XX blows the HD650 out of the water when it comes to...

It's an 1/8" jack with a 1/4" adapter.

Do you have an amp capable of powering a planar magnetic headphone? They require a lot of power to get the most out of them.

They're two completely different headphones. Not really comparable. I own both the HD650, which is identical sound wise to the HD6XX, and the HE4XX. Sound signatures are different, one is a planar magnetic and the other is a cone dynamic. They basically share no similarities besides the fact...

I noticed this as well. I'm listening to them through a Schiit Lyr and I have the volume just under halfway on a 6W amp. These 32ohm cans require the same amount of power as my 300ohm HD650. They definitely need that power to get the most out of them.

I've heard the Pro 900 and I don't find them all that special. My friend owns them and he swears by them but I just don't see it. To me they have overpowering bass and less than average soundstage. Like listening to music underwater. The problem is that it's completely subjective. One person's...

I picked up my HE4XXs this morning and I am seriously impressed. This is my first pair of planar magnetics and the only headphones I have on hand to compare them to are my HD650s. They easily hold up to my HD650s sound quality wise. Absolutely worth the money. Bass response is a bit more punchy...

Mine were also delivered today but I won't get to try them out till tomorrow as they were delivered to my apartment complex office while I was at work and now the office is closed. They got delivered 10 minutes after I left for work which is mildly infuriating.

Oh........great.

How did you get ahold of them so early?

I pulled the trigger on these as well. I've never owned planar magnetics and only have very limited experience with them. I've been wanting to get a pair for a long while now and these popped up at an awesome price. Figured why not? I'm sure they'll be well worth the money. I am not at all happy...

  You don't have to imagine. We are already well beyond that. At CES Nvidia had a 12K setup, three 4K monitors in Nvidia Surround mode, running off of four Titans in SLI.    Check it out: http://www.maximumpc.com/ces_2014_gaming_12k_nvidia_video

  Oh well I thought you were actually maxing the game. Never mind then. I run it with all the settings maxed out including texture resolution and AA with no vsync because I have a 144Hz monitor. I average right around 60-70 FPS with dips going down to 35-45 FPS at times. However, when I'm...

  Crysis 3 is absolutely fantastic maxed out. What are your rig specs? It takes the full power of my two 7970 GHz Editions to max Crysis 3.

          Thanks guys! 

  That one spent a little more time in Photoshop than the others. If you know what I mean......
