I recently got a Roku 3 and absolutely love the wireless audio-broadcast to the controller and have been looking for something with relatively similar technology that's flexible enough to work with multiple headphones (one broadcast, multiple receivers); does something like this exist, or should I look for a good audio-splitter? I currently have an HTPC, Roku 3, Bluray-player and dvr/cable-box connected to a TV via HDMI cables; the tv-audio then routes to a Pioneer VSX-D498 receiver with subwoofer/speakers.
My aim is to have some sort of wireless-broadcast device that can take the audio-out from the tv (or VSX-D498) and send it to any/all wired-headphones that have corresponding wireless/audio-receiver dongles/devices (bring-your-own headphones). I've played around with a cross-platform program called Soundwire that broadcasts the HTPC-audio over WiFi to any phone/tablet with the SoundWire app/client installed and running while on the same network, but it tends to have slightly more latency than the Roku-controller, and the HTPC audio-feed doesn't currently include the bluray-player, cable-box, or Roku 3.
If this isn't easily possible, I would definitely settle for a good powered audio-splitter (or similar tech) that can maintain the original audio-feed and max/sound-levels to each pair of headphones (preferably with individual volume controls for each pair of headphones) preferably in a form-factor that isn't prone to headphone-cable tangle/mess if 2-5 people have headphones plugged in while sitting on a couch. Suffice to say, there are competing/fluctuating interests/preferences between people who occasionally/often want a silent environment and people who occasionally/often want to watch movies/shows; only rarely/occasionally does everyone (8 people) want to watch something together with speakers. Thank you in advance for any recommendations.
