So I have a pair of Klipsch s4 I think they are, and they sound awesome but, the cord has a short in it and if I move while wearing them they sound all cracked out, so I am sad and need a new pair of headphones, and I like the noise isolating silicon headphones like these, but I am also interested in some around ear headphones.  Now this is my first post on this website, and I've read some stuff on here and other websites and I'm just way overwhelmed with all the information and technicalities.  But I love how my current pair before getting messed up allowed me to hear things so much clearer and I was wondering if for my next pair with either a similar style or around ear headphones I should pick.  The primary source I would plug it in to would be my iphone, but if it has a long cable, then I would plug it in to my home theater receiver for gaming when my family is asleep (instead of in silence as I do now).  So a long cable isn't a deal breaker, but would be nice.  So what headphones should I get?  I'm very confused and not even sure what I'm looking at when I look at all the technical stuff on websites.  They will get used primarily walking around campus, but in a few weeks I am going on a big family trip out of the country, and need to get new headphones before we go.  So things I'm specifically looking for:
 
In or around ear
decent noise isolation/canceling
neutral sound (i don't need beats by dre blowing me up with bass or anything like that)
$200 or less (I am willing to go used)
can be powered by my iphone, but if I can plug into my Onkyo tx-sr608 will be able to take advantage of that
      (If it has a long cable for me to use with my receiver, then I would be used for music/games/movies in that order of frequency)
 
Other less important consideration:
5.1 sound, I've seen some of those and if I can plug in my receiver that would be pretty nice
replaceable cord so i could have a short cable for daily use, and a long one for my receiver
 
and one that absolutely does not have a mic on it....
 
 
Thank you very much for anyone that takes the time to read and respond, and sorry I am not more familiar with all the jargon or information related to this topic

There are a number of good possibilities I'd you've never had headphones. Right now I would recommend the Koss Tony Bennett Special Edition. The are discontinued versions of the Koss ProDJ- 200,which are $130. But if you have a Tuesday Morning store near you, they have the TBSE for $50, and if not you can order them for $70 from Adorama. They are vey well built, all-around headphones. Search on here for DJ-100 or DJ-200 and read what people say about them. They do say "Tony Bennett" on them in gold script. So that may be a turn-off.

The are lots of threads here on "under $100" "under $200" and so on, so search for those to get ideas.

I have read some threads on the <200, but when I look in to some further they often say they require an amp, and if I I were to use them with an iphone it would be very quiet even with the iphone at max volume... so that is what was throwing me off a bit, and not too many of them that I read about mentioned any kind of noise canceling or isolating.  And is it prudent to assume that typically around ear will have better sound than in ear???   Plus I can't imagine I'd have even a slight chance for a replaceable cable with in ear headphones.
