+Ever wanted to share a movie or song with a friend, but you did not have one of the those audio splitters lying around? Here is an easy trick that you can do for free on your macOS to output audio to multiple devices at the same time.

+
+*You **don't** need one of these - Photo: [Amazon](http://www.amazon.in/Belkin-F8Z274bt-RockStar-Audio-Splitter/dp/B00904WS2K)*
+
+`⌘+space` to open up spotlight and type in **Audio MIDI Setup**
+
+Hit the **+** menu on the bottom left of the window and click on **Create Multi-output device**

+
+Select the audio devices to simultaneously send the output. In my case it was the two headphones. This does not have to be headphones. You could for e.g. have the audio play through your laptop speakers as well as your HiFi headphones at the same time You will need to check drift correction if your audio devices have different sample rates - check this just to be safe :)

+
+Change the name of the new device to something meaningful - "All Headphones" in my case. 
+
+Voila, you can now choose the new device as your speaker from the Audio icon in the menu bar.
+
+Gotchas
+
+Beware that you need one of the headphones to be a USB or bluetooth as there is only one 3.5mm jack in your Mac. 
+
+Bonus
+
+The **Audio MIDI Setup** app is a treasure trove of good stuff. You can combine together multiple devices to create some pretty complicated setups for free. See this 4.0 setup for example.
