We have developed an Android app plus a Windows server app that can be used as a Wireless Headphone. The Android app can be purchased from Google Play store. User can connect the TV headphone jack to a laptop microphone input using a male-to-male 3.5mm audio cable. The server on the laptop will send the audio coming from TV to the Android smartphone and user can listen to the audio using any kind of headphone. Please note that you can connect any other audio device that has a headphone jack to your computer/laptop with Windows operating system.
This software is the server side for audio streaming. To be able to use it as a wireless headphone, user needs to install the "Wireless Headphone" Android app on her/his smartphone. Get the app from Google play store: https://play.google.com/store/apps/details?id=com.ateclabs.wirelessheadphone
