AudioZone is a free Android app developed by Vertical State Ltd. It falls under the category of Multimedia and specifically the subcategory of Music & Radio. This app allows users to tune in to TV audio via the earphones of their phone in various venues such as sports bars, airport lounges, and more.

One of the main features of AudioZone is its ability to turn your phone into a wireless TV headset. This is especially useful when you want to watch TV without disturbing others or being disturbed by external noise. Simply install the app, connect to the venue's customer WiFi or the "AudioZone" WiFi signal, and press the speaker icon to start listening. The audio will only be available through wired or Bluetooth earphones, ensuring a personalized listening experience.

If multiple audio channels are available, AudioZone provides a drop-down list for users to choose from. Switching between channels is seamless and can be done at any time. Additionally, users can optimize their listening experience by adjusting buffer settings. Larger buffers help resolve audio breakup, but may introduce a slightly bigger delay in audio. Users can switch between buffer settings to synchronize audio and video if necessary.

AudioZone is a reliable and user-friendly app that provides a convenient way to enjoy TV audio in various settings. It is completely free to use and users are encouraged to contact the developers for suggestions or assistance with any issues they may encounter.
