SplitSound

One tab on your headphones.
The rest on your speakers.

SplitSound is a Chrome extension that lets you choose the speakers or headphones for a single tab. Everything else in Chrome keeps playing where it did.

Coming soon to the Chrome Web Store

Free. No account, no ads, no tracking.

How it works

  1. 1Open the tab

    Go to the tab whose sound you want to move.

  2. 2Click SplitSound

    Click the SplitSound icon in the toolbar, or press Alt + Shift + O.

  3. 3Pick a device

    The tab plays there from now on. A ♪ on the icon marks a moved tab. Pick "Same as the rest of Chrome" to move it back.

What people use it for

  • Two windows, two outputs

    Play two Chrome windows on two different outputs at the same time.

  • Video and a second tab

    Keep a video on the desktop speakers while another tab plays on your headphones.

  • Film on the TV

    Send a film to the TV while music stays on the computer.

Good to know

  • You need two output devices connected to the computer, for example speakers and Bluetooth headphones.
  • Only the tab you picked moves. Other tabs keep playing on the normal output.
  • Chrome shows its "this tab is being shared" marker on a moved tab. SplitSound takes the tab's sound and plays it again on the device you picked. Nothing is shared with anyone.
  • Full screen stays inside the Chrome window while a tab is moved. Press F11 to fill the screen.
  • Moved tabs go back to normal when Chrome is closed. If the device disconnects, the tab plays on the normal output until the device is back.
  • Chrome's own pages (settings, the new tab page, the Web Store) cannot be moved.

One-time setup

Chrome only shows the names of your speakers and headphones to an extension that is allowed to use the microphone. SplitSound asks for that once, opens the microphone for an instant to read the list, and closes it again. It never listens and never records.

Privacy

SplitSound has no server. The sound stays inside Chrome on your computer, and nothing is collected, stored or sent.
