Hi everyone! I know a version of the headphones to playbar/playbase question has been asked in other forums within this community, but as far as I was able to see, none of the questions discussed use of an optical audio splitter as a potential solution. I am trying to connect wireless headphones (Sennheiser RS 175) to an existing system that includes a Sonos system (Playbase and two Play:1s), a tv (Sony XBR55X900E), and multiple other media connected to the TV (bluray, gaming system, Tivo, etc.). In order to use the headphones at night (instead of the full Sonos system), would I need to invest in a Sonos Connect or would it be possible to use an Optical Audio Splitter (e.g., VIMVIP 3 Way In / Out Digital Toslink Optical Audio Splitter Manual Switch) to direct sound from the TV to either the Sonos system or the headphones? Thank you in advance for any of your suggestions, and happy holidays!
