Hi. I've been searching for an app which plays the TV's audio to my smartphone so that I connect to my wired headphones. I've seen this feature only on Samsung TVs. Would've been cool if there was an android tv app for it. Do share if you guys know about such an app.
I’m not familiar with any app but, you can pair Bluetooth headphones natively with the majority of Google TV devices, and if you insist in using a wired headphone you can then buy a very inexpensive Bluetooth receiver
