Hello!
Here's my current set-up:
TV - BRAVIA XR A80J
Receiver - Denon AVR-S650H (150W X 5) 5.2-Ch.
Speakers - MartinLogan Motion 3-1/2" 65-Watt Passive 2-Way Center-Channel Speaker & 2 ancient (but awesome!) a/d/s L8e speakers
oh - and a PS5
I've been having trouble hearing the tv audio in the kitchen, and the Denon Home 150 speaker is NOT cutting it, so I took a chance and ordered a pair of Sennheiser RS 195 RF headphones.
My question is about installation. The 150 connected to the TV via wifi (with many issues), but the Sennheiser base plugs in directly with an optical digital cable.... the port of which is currently in use. I ordered this: "3 port Toslink Splitter with Optical Cable". Is that what I need?
I'd also really appreciate step by step (like I'm 5) instructions on how to add the splitter (if that's right) and then the Sennheiser base.
Thank you SO much!!
Betsy
