Ok, recently, i just bought a new Sony psp headset with microphone, here is the picture of it http://www.pspworld.com/sony-psp/images/psp-headset.jpg And i also have a remote, which is NOT a Sony brand. The microphone is connected to this remote, and remote is connected to my PSP. My PSP is the phat 1, and the remote i bought is working, i tested it, i am able to press and play music. But I am not sure why, people cannot hear me when i talk in Killzone Liberation (PSP game). Is it because the remote is not a Sony brand? I find it wierd because the remote is working well. I can use it, and i can also hear from the heatset. But i just can't talk, nobody is able to hear me. Can anyone please tell me why? Oh ya, and that remote is for PSP. Although it is not a sony brand. It works and fits for PSP. looks exactly like a Sony PSP remote. but this is without the PSP logo on it.
