Let me start off with a list of my technology. I have a dynex 36 inch flat screen tv. A PS3, a pair of seinhesser RS 170 wireless headphones, and a Vizio 2.1 sound bar with subwoofer. I have the PS3 connected to the sound bar via opitiCal cable. The PS3 connected to the TV via HDMI cable. The tv connected to the sound bar via rca cables. I just recently got a set of Seinhesser RS 170 wireless headphones and this is where my question comes into play. So far all I can figure out is I can connect the headphones to the TV via a headphone jack on the tv. But I don't get anything from the soundbar or PS3 and there is an awful hiss sound on the heaphones. The headphones have two settings of 0 dbs or -8dbs the sound was worse on -8 but got better when I switched it to 0. Still has an awful hiss but not as bad. I would like to know how to get these headphones to not only produce that crystal clear sound I know they are capable of but also to get everything connected together. I am not super technologically savy but can kinda work my way around. Please help. I could really use it and also make it easy to follow. Thank you!
