Negative Positive
Title: terrible signal, hissing
Review: lots of positive reviews on these is what triggered my decision to buy them. i tested several different positions, all channels, power sources, audio cables to no avail. i decided to give the sennheiser RS120's a try and have had a much better experience with them. they sit more comfortably on my ears as well, charging is easier (you just drape them over the metal bar.. no need for positioning).. highly recommended. one thing i do like about the sony's is that they power off when there is no signal.
Is the review positive or negative?
