Quiet sound on my laptop

[aperativchety]

Hi guys, I am expiriencing an annoying problem. Recenlty i bought Creative Hitz headphones and I noticed that I am getting louder and better sounding with deep basses sound while using them on my iphone than using them on my laptop with Windows 7 Ultimate x64. I don't like this and I often find myself using the phone to listen to music rather than using the laptop. But i don't think the problem is in the headphones. I mean the sound from this laptop specific is quieter than the sound of my mom's HP. Maybe the problem is in the laptop?
So if anybody knows how I can fix this, please tell me.
Laptop : Asus K53SD
Soundcard : Don't know what it is, i'll drop a screenshot from the device manager tab
Headphones : Creative Hitz MA2400

What is the Razer Surround Audio Controller" used for?

In the Control Panel/Hardware and Sound should be a Realtek HD Audio Manager. There are Equalizer settings that will give you control over the sound and more bass if you want it.

Here is a screenshot from mine.
