READ THIS BEFORE BUYING A BEATS LAPTOP
I also have a HP dv6 with beats. I bought it for the hardware and price. The speakers are loud and produce very good sound for a laptop. The beats program that is pre-installed is also good. It lets you change the EQ with a fairly wide range of sliders. On the other hand...
THE DRIVER IS TERRIBLE!!
By going into control panel- hardware and sound- sound- speakers and headphones- tone controls, you can see why it sounds terrible without beats activated (shortcut: fn+b to turn it on/off). By deactivating beats, the bass slider goes down to -12 and the treble goes down to -4. With beats activated, the bass and treble are at +4. The driver simply changes the EQ to make it seem like the software is making the music sound better. I usually hate any kind of sound alteration (except for when using the speakers because the +4 with beats on takes full advantage of the laptop's amp). So I moved both sliders to 0. I would be perfectly fine with the driver IF IT DIDN'T RESET THE SLIDERS EVERY TIME I TURN THE LAPTOP ON. Putting the sliders on 0 is very easy and takes less than 30 seconds, but it is annoying when you have to do it multiple times a day (every time I turn on my laptop and want to use my headphones). Also, I tried uninstalling the driver and replacing it with a generic one, but the laptop rejects the driver and automatically installs the beats driver.
I don't have much experience with laptop headphone jacks and sound cards, but without anything playing, my Audio Technica M50s pick up a decent amount of white noise/ static. This is very annoying because I hate noise cancelling headphones which do the same thing. This is because I believe that the quality of silence is very important in sound quality. Without any white noise, music sounds much more crisp. I just ordered a Fiio E10 Olympus DAC which will hopefully bypass the sound card and headphone jack, and eliminate the static (I'm sure that it will also increase the general sound quality).
BOTTOM LINE: I would never recommend this laptop to an audio enthusiast (especially if they plan on using $100+ headphones with the stock headphone jack/ sound card). The software is fun occasionally, but the driver is terrible. The speakers are good for a laptop, but most people have external speakers anyway.
