after sometimes it will turn yellowish
+it is dust magnet.

try other product
the other 1,cannot remember the name

+1

i used zagg in my ipod touch before...

Con
1) it is thick a lot, i that time use full body cover for that.
2) hard to apply, very sticky.
3) Dust magnet +1
4) very sticky on finger feel
5) Will turn yellow after as the time pass
6) Expensive for me.

Pro
1) Due to the thickness, it does protect from sharp objects...but who are so stupid put phone with keys in same pocket!?
2) No finger print like matte SP (due to stickiness, i rarely use finger on that LOL)
3) Grip is strong ( Due to stickiness) 

Okie..that works...But then the sounds are still not clear as the sony headset..=S
Plus...I still can't press the play/pause button...I wonder why...=[
