just swap it back when u wan to claim for warranty.

Overprice becuse u could get a cheaper headphone with better sound quality. 
Yeah. I think RM400-RM500 is ok for this headphone.

Added on April 29, 2011, 6:57 amits raining, and i'm doing another battery test.

this time i'm using powersave mode and screen brightness at lowest. activity only surfing and playing music. 



see u guys in a few hours 

is it only me here that did windows clean install?

use cd..my bro has it..
so basically my lappie is not really a hp laptop..in terms of software installed

yesh, its overrated.

just kidding bro. the speaker is ok, quite loud but the sound will distorted when i max it. it doesn't have subwoofer but u still can hear the bass.. unlike my old Compaq laptop. it has 4 speakers btw.

bout the headphone, i'm not so sure... the sound is awesome when i use my DV6. When i plug it into my compaq the sound quality is terrible    but when i boot into my linux box in that compaq the sound is awesome again.    i'm using system-wide equalizer in my linux, so i think the keypoint here is equalizer since the DV6 have beatsaudio and my linux have alsaequal.
