I had to keep myself from laughing when this girl today was buying a set of Dr Dre Beats Headphones for $259 .... yes $259!!! I can't believe the hype of those things... News Flash - "Beats" by Dr Dre is an EQ (software) setting and the Headphones are made by Monster and are no different that any pair of $19 headphones. Monster of course became famous from and is well-known as the biggest offender in HDMI cable scams that trick consumers into paying $60 for a cable that does the same thing as a $6 cable.
Here is what the Full "Beats Audio" experience is
1. Redesigned headphone jack – reduces ground noise because it is made out of plastic (so are all $6 cheapies)
2. Discrete headphone amp – more powerful with better stereo separation (on the pc side, not headphones)
3. Dedicated audio island – isolates audio components on the circuit board (again on the pc side, not headphones)
4. Function + B – engages Beats Audio profile (Equalizer setting that enhances Bass - can be done buy increasing the bass on your phone or mp3 player yourself)
So the only the only part that actually has to do with the headphones is the plastic jack 
Hey but at least she has a big red B on the side of her head to impress her friends.
