I just bought Maya U5 yesterday. I connected it to my Wintel 7 laptop and paired it with AIAIAI tracks headphone.
My first impression after hearing it a while is there is clear hiss/noise in the background when playing high freq part of a song.
Is there any solution to this problem? I already change all setting in the VIA USB audio deck but it's still there.
I'm also aware that the U5 is quite weak when handling EMI or electrostatic discharge.
If you enable the Qsound option, when disabling QSizzle and EQ, check it.
And then, if you have the same symptoms when disabling Qsound, please change other headphones.
This product passed EMI test.
The issue of noise that happen in the background, please change other headphones then check it.
