Thing that most people forget to quantify when they consider price is the user experience, and a large part of that is very personal and linked with taste.
When I brought my wife her laptop recently I paid a fair bit extra for a better model that was designed in a way that I knew she would love. Specs wise it was the same as a cheaper model, and she could get the exact same function out of a laptop a few hundred pounds cheaper.
But even after 6 months, she still loves to open the laptop and use it, and still gets that nice warm feeling when you feel like you are using something that i nicely tactfully designed, and fits your perception.
Headphones, phones, tablets, laptops, anything techy, if you go by the pure numbers, then higher brands are almost never worth the price.. but they are worth it to a lot of people as the small differences in design and branding add a huge amount of value to the user experience.
