I am thinking of getting some phones, in addition to my speakers at home, for if I need to keep things quiet. So what I'd like as something good sounding, pretty neutral, and comfy. My Denon D2000s at work are great, but of course they won't make those anymore. Also something high impedance would be nice because I'm going to nab a Fireface UCX I think and it has a 30 ohm output impedance on the headphones (for some reason).
 
So that's what I'm after. High impedance if possible, nice and comfy, good sound. Open/closed doesn't matter. I have some candidates in mind, just seeing what others like and recommend as well.

I have a small sampling of different headphones. For me the KRKs are the winner. Price is reasonable, they are the most comfortable (with no pressure on the ears - they designed them for long wear comfort).

Best of all, they capture for me anyway the range that sounds closest to listening to monitors. Not too bass heavy.

I have other headphones that have more bass and maybe more high range sparkle, so they make everything sound nice - even a bad mix of a song.

So the KRKs I think provide a truer real spectrum that helps increase my chance of getting a mix right.

ATHm50 by audia technica is onebof the better buys. Imho it outperforms headphones costing more.

You can't go wrong with good ol' AKG K240's.

I have the ATH M50'S and I like them but not near as much as my Beyer Dynamic DT 770 Pro's. The DT 770's come in different impedances. I have the 80 ohm ones and they work great.

I've been using the Ultrasone's Pro 750 for a couple of years now, and I'm very happy with their neutral & natural surround sound, very good sounding, as well as comfort-wise. I generally do my music work at night (when the little ones are sleeping) and barely notice any fatigue after a few hours of use.
 
Here are some of the specs:
 

• S-Logic™ Natural Surround Sound
• Dynamic principle
• Frequency range 8-35.000 Hz
• Impedance 40 Ohm
• Sound pressure level 94 dB
• MU Metal bufferboard, reduced field emissions in accordance with ULE (=Ultra Low Emission) standard
• Driver 40 mm titanium-plated
• Weight 295 g (without cord)

Ps.
I also use it for gaming and the clarity of pin-pointing the locations of (surround) sounds are quite remarkable.

BTW....
the ultrasones discussed above, are awesome..
one of my all time favorite sets i've used..
 
i cannot afford them,
i use AKG240's
and like them.
 

I'm using Sony MDR7506.  Great for the price range. 

I have the Ultrasone 750's also.  Fantastic Bass, scooped mids, and very bright top end.  They sound closer to monitors than most any other headphones, which make them great for placing microphones and live tracking.  But trying to mix with them may make the results somewhat dull due to the exaggerated high frequencies. They are also not as flattering as standard headphones for clients on location.  
 
ATHM50 are probably the most popular closed back phones today, they have a very clear, dynamic, and flattering sound. I really liked the sound of my Yamaha RH10ms before they broke.  Clients' jaws dropped at the results of their recordings with them.
