Bests & Worsts Reviews from Amazon

I just received this today for use on a MacBook Air (why they only give you one audio port on a laptop puzzles me). First time I tested it, it didn't work- but then I figured something out. It's more of a Macbook issue than an adapter issue. I plugged the adapter into my MacBook with the headphone plug already plugged into it, which worked fine. Then I plugged in the microphone to the microphone jack and... nothing, it didn't work. I went into the sound settings and there was no option to configure anything to fix the issue, the only sound input that showed up was the built in mic. I unplugged the adapter from the Macbook. The second time around, I made sure both the headphone & external mic cords were first plugged into the adapter and then plugged the adapter back into the Macbook. This time the Macbook recognized the external audio input, I selected it and it worked fine. Years ago a mic plug was a mic plug. Now they're all "smart" plugs that try and sense what you've got connected and configure themselves automatically based on what they think you need to do. As a result, you've got to make note of the order of how you plug them in. The multi conductor nature of the male plug does make it kind of delicate & susceptible to breaking off, so I make sure to be careful when plugging and unplugging it. At $10 the price is a bit high IMO. Overall not a bad adapter.
