In my opinion, if you try to get something else and don't get the beats for her, she will be either unhappy or disappointed. I'm sorry, but being sixteen , you just want to be in the crowd or at least not stick out with something they don't understand.
As far as headphones goes for her, her friend will affect her decision on what sounds good to her regardless what the truth is.
If you plan to get a different headphone for her, don't even try to convince her that it is better.
I say find something that has comparable bass and definitely the looks gotta be good and not to you, but to her.
for me, I would of just made it simple and get the beats for her or either that get something else beside headphones. To me her mind is probable set on those as far as headphones. I don't see anything is wrong with that, sure in reality it may not sound as good as other headphones, but the fact that she thinks it sounds better or worth the $180 than the money is well spent. kind of like a placebo effect. also if she will be using it a lot. Basically how much the headphone or any product is worth is how you value it.
hopefully you get the idea, if not, go around and tell people you spend hundreds and hundreds of dollars on headphone and see the reaction.
or better yet imagine you wanted a particular headphone for christmas (grados, At's, senns, etc) and you end up finding the beats headphone under the tree.
