1 out of 5 eggsIncompatible With Certain Heaphones

Pros: None. The Mic never worked.

Cons: On another site several comments are answered stating that certain headphones do not work with this. My Bose Headphones do not work with this. I believe it is misleading to not make it clear.

1 out of 5 eggsBroken after 6 months

Pros: Worked great for five months.

Cons: My XBox One headset is popping and audio/mic going in and out. I thought it was the XBox One Stereo adapter and purchased a new one for $30 dollars. Nope, it was this cheap connector that has a short inside.

5 out of 5 eggs

Pros: What can I say? It's a simple product with a very specific use and works as intended.

I mean, I legitimately do not know what else to say about this product. It's a splitter and it splits as it should.

Oh, this product is a lot cheaper here than on their site AFAIK, and seems a much simpler route to go compared to the crazy contraptions I found while roaming the Googs.

Cons: I dunno, it hasn't made me rich beyond my wildest dreams yet? :/

Other Thoughts: Hey, if you have a headphone plug and a microphone plug, and you need them to go into the same hole for $6 or less, this is the product for you!

And as for the point brought up in other reviews, on the matter of being unable to see which plug is which, simply hold it so light hits it. It's not as hard to see which is which as it's been made out to be.

5 out of 5 eggsWorks as a combo to headphone+mike splitter!

Pros: It can be used to split a 4-position combo audio port into a 3-position (stereo) headphone port and a 2-position (mono) microphone port. Really! The (Newegg) title is misleading: the ground is common and so there is no way to split the other 3 (signal) positions into 2x2 independent signal positions. (For those born after 1965: 2x2=4; sorry for this stinker but once in a while I have to vent). If the mike socket is 3-port indeed, its 2 signal positions must be shorted in the splitter.

For the one-egg reviewers: if you receive the wrong product have it returned. And if you have connection problems try to figure out where that bad connection actually occurs. Startech does not make bad stuff but if you are so unlucky to receive a lemon just have it replaced. And do not pollute the reviews!

Cons: The icons on the separate black sockets are pretty much unreadable. So take apply a small piece of pink/green heat shrink on the mike/headphone socket.

4 out of 5 eggsCONDENSER MICS ONLY!

Pros: Cheap, snaps into place well, works well with dynamic microphones, and has headphone connection.

Cons: Does not work with condenser microphones!! Not stated in description.

Other Thoughts: This splitter only works with dynamic microphones! I was hoping when I bought this that I could use a shotgun condenser microphone, but the iphone did not recognize the device and continued to use the iphone mic. I tested it with a dynamic mic I had and it worked without any problems. It turns out that you must buy different adapters for condenser and dynamic microphones. It is a good cheap adapter but I wish it had been more specific as to how it could be used.

5 out of 5 eggsHandy Device

Pros: Combines separate connectors for headphones with microphones into a single 4 conductor 3.5mm plug.

Cons: Kind of pricey... but cheapest of all the alternatives.

Other Thoughts: Use these to adapt my two sets of PC/Gaming headphones to iPhones, Macs, and newer PC hardware. Works like a charm!
