I used this to connect a wireless microphone to my MacBook. Because the headphone jack on all Macs is designed for use with a combination of Mac headphones and microphones, you can't just plug in a standard microphone. With this little adapter, I was able to connect a wireless receiver from my microphone to my Mac, and then with a karaoke website and Mac streaming to Apple TV, my soundbar TV became a full-featured karaoke machine. All for less than $10! Pretty good compared to buying a separate machine probably for 100 and you have to keep it somewhere. I'm sure there are many other uses for this adapter but I got it for exactly that and it worked great. What can't be said about the singers, but that's another story.
