Requesting Recommendations for Noise Cancellation Headphones

[Silentium]

Hey there!
 
As the thread title implies I am looking for a recommendation for noise cancellation Headphones.
 
Now the Circumstances are the following: I am working in an open office with a lot of people. Problem is: I am a extremely sensitive to significant background noises.
I couldn't care less about the noise of an airplane engine or something similar. But I go insane when I have to listen to something like a dripping tap.
Now in my situation it's one dude cracking peanuts all the time (sitting 10 meters away) and one dude who is sniffling faster than I can breath as it seems (sitting 4 meters away).
I am mentioning this specifically because it sounds like noise cancellation headphones are mainly filtering out regular background noises like humming which I don't really care about.
 
So what I am looking for is Headphones which:
-filter out these kind of noises rather good and/or which are shielding me extremely well
-do not leak a lot of sound themselves. It's enough that I am bothered by other people. I don't want to bother anyone myself.
-do not generate a lot of noises themselves. If they are catching up phone noises or electric vibrations. There is no use to filter out some noises and generating others.
-have a normal plug usable on PCs. (additional use of batteries is fine)
 
In addition they should be rather "cheap", meaning not more than 150€ / 170$.
 
What does NOT have a lot of priority is great sound quality, including highs or base.
 
My primal use of these headphones is to not go insane at work.
 
What I found in affordable reach on amazon is:
Audio-Technica ATH-ANC7BSVIS - but they seem to pick up / generate new background noise
Sony MDR-ZX750BNB.CE7 - but they seem to be painful if used for more than an hour
 
Any recommendations are welcome!

I had the ANC7B and the noise canceling is pretty good but they do leak out quite a bit of sound. Have not heard the Sony.
 
I think your best bet for high isolation and low leakage would be a pair of in ear monitors. I like the Shure SE215. Lots of isolation (passive, not active), comfy, and no microphonics (cable noise). If you don't play music the loudest thing becomes yourself. That might drive you crazy, I can't stand using them without music on.

Thanks. I forgot to mention that I have to put them off and on quite often, so I would prefer something which isn't in-ear.

I own the Sony MDR-ZX750.  They only do well with those engine noise kind of sound.  They definitely do not filter the kind of noise you described.  I also have 2 other active noise cancelling headphones (the Klipsch Mode M40 and the Panasonic RP-HC500) and they are also only blocking the engine noise.  I think what you actually need is a pair of passive noise isolating headphone, They would do a lot better in your situation. I agree with JustinBieber that IEM would be a better choice.  But if you definitely do not want "in-ear", perhaps other head-fiers could help with the suggestion.

After talking to a friend and your feedback about noise cancellation I decided to go with "Beyerdynamic DT770 M", which is a special model of the DT770 focusing on passive noise isolation.
and with 150€ still affordable.
 
Will take a couple of days till I can test it and can tell you and people who might stuble upon this thread with a similar problem whether it actually did the job.
