Absolute garbage. Once "YouTube Audio Mode" is activated, the video continues to render at the set resolution of 1080p or 4K60. You can check the GPU usage in the Task Manager; it's 10-15% depending on the video resolution. But if you disable the magical "YouTube Audio Mode" and manually lower the resolution to 144p, GPU usage drops to 0.4%.

It simply displays a static image, but the entire video continues to consume resources in the background.

Fake. The bandwidth is the same as watching 144p video but without video. Doesn't make sense.

Working on Lenovo ThinkPad T16 with Windows 11 Enterprise 25H2. Intuitive use.

Excellent and very practical extension.
YouTube Audio Mode solves a real problem for anyone who wants to listen without wasting bandwidth on video. Audio-only mode works with one click, and the extension automatically lowers video quality without affecting audio playback.

What I liked:

Significant data savings.

Clean, modern UI with a pleasant visualizer.

Clear statistics showing saved bandwidth and listening time.

Smooth integration with YouTube, no interruptions or reloads.

The extension is lightweight, privacy-respecting, and requires minimal permissions. Perfect for Quran, lectures, and podcasts
