Audio Only for YouTube™ is a free Chrome extension developed by Sevina. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This extension allows users to listen to audio-only content on YouTube and all embedded videos.

The extension provides a toolbar button that serves as an ON|OFF switch. When the button's color is red, the add-on is active, and when the color is lite grey, it is inactive. By default, the add-on is set to active. When a user opens a YouTube page and plays a video, the add-on automatically loads the audio source only and prevents the video content from loading. This helps users save their internet bandwidth as video content is larger compared to audio content. Additionally, when users only want to "listen" to a video, they can choose to not load the video content at all.

It's important to note that if any errors occur while the add-on is active and the audio is not playing, users can simply reload the page once. However, it's worth mentioning that this extension does not work for live video items.
