Also SoSpecial, thanks for the explanation. However, doesn't technology advance... Even if they are timeless, shoulnd't they be able to make better headphones in 5ish years.

So even at $120 bucks, the beats are trash? Also it's cheap because I get them through employee accommodations. From what I know out of the three brands the Sennheiser is the best. I was wondering... Why do some people like the Bose and the Beats so much. Is it due to great marketing, or is it...

Okay I know not everyone likes the Beats... However, I can get the Beats for a very cheap price.   Currently, I'm debating if I should get the Beats Studio, QC15, or PXC 450. Also I had a question about the Sennheiser. Why has the PXC not been updated recently? I mean that thing has been out...
