Thanks for your reply xxkid123.
I'm under the Version Kernel 126.96.36.199 sj0829.kwon@SEP-08 #2
Version Number: FROYO.TLJL3
I'm not familiar enough with this technology and I'm not really sure what exactly you want me to look, could you help me out looking if there is any bug or error reported?
And for the background, there is no background at all. I'm alone at home with no background sound. If you could hear what I mean, you would understand. It looks like more the sound is heavy or acute, less the headphones will be able to play it. Like if there is a very pinch sound, it will be able to play only a part of the pinch sound, not at its full power... well not sure if you're understand, I have a crappy english too
Also, I have an other pair of headphones (MLG gaming headphones) that I just plugged in my phone and it works awesome.. so its just a problem In-Ear headphones/Phone
