IPhone 4 and beats solo or iPhone 5?

My birthday is coming up, I just asked for money and these are my options for what I'm buying. I'm really not too sure what to do here because I have heard the iPhone 5 is a lot better than the iPhone 4. But, if I get the 4 I can get beats too.So, I would just like your opinion on what to do and which phone you're thinking is better

Beats are overated you can get decent headphones for much cheaper however the iphone 5 is much better than the iphone 4

Iphone 5 is hardly better than the 4, it just might last longer unless you somehow get your hands on a brand new unopened 4

Deffinetly iPhone 5 beats are really bad and have a bad sound quality. IPhone 4 is old and does not have Siri, overall deffinetly the iPhone 5

IPhone 5, there are a lot of better headphones out there.
