I can see that many folks have struggled with using this adapter, so this review is intended to clear up many issues that may occur, as the manufacturer seems unable to get the message across.First, the terminology:T = Tip (the end of the plug)R = Ring ( a ring of metal in the middle of the plug)S = Sleeve (the part of the plug closest to the plastic jacket insulation and cord)Note that the CTIA standard uses the sleeve part of the TRRS plug for the MONO connection of a Microphone. Here is where the problems can occur. See my illustration.These adapters do not make any allowance for a MONO TS Microphone plug.Inside the Jack in this adapter, the Tip and Ring of a TRS Microphone plug ARE SHORTED TOGETHER and wired to the TRRS MONO Sleeve of the plug on this adapter.Allow me to explain why this causes so many problems for end users:Many Mics are wired to a TS plug. If you insert that type of plug into this adapter, the sleeve of the TS plug meets with the Ring connector inside the jack, which is shorted (connected) to the tip of the plug. So this wiring shorts out your microphone, and you hear nothing!!A Stereo microphone with a TRS plug will only give you mono sound using this type of adapter, as the Left and Right are connected together. The TRRS CTIA standard only allows for MONO input.This adapter is simple wiring, no electronics involved, so using the wrong type of Microphone is not necessarily the fault of this adapter, but an in-compatibility with your device. There are many types of microphones out there, so keep this in mind. Discussion of microphone types is too involved to put in this commentary.The most important thing to take away from this is to keep in mind the short inside the pink microphone jack of the adapter between the Tip and Ring of the Pink TRS Microphone Jack. It is a shame they didn't just leave the ring connection disconnected, as a Stereo microphone would still have one side connected that way, and a mono microphone would have worked just fine.This is very typical of the lack of engineering and testing of products in China. They build a product and shove it out the door, with little consideration for the customer. They steal the technology we have built over decades, slap together a product, and don't put much thought into functionality, and definitely not durability. Forget about quality control.I hope this makes your shopping experience better. Have a nice day!The cable matches the picture and description, and the connectors are nice and snug on both ends.Does the job of allowing you to use both earbuds and microphone from a single jack on your phone. This cable is also nicely color-coded and the cables are braided and seem high quality.Works as describedThis splitter let two of us plug separate headphones into the Roku controller, so we could watch the TV without waking the rest of the family. Sound quality was great.It does the jobI have a nice set of headphones (no mic) that I wanted to use when editing videos, but being TRS headphones and the desktop's front jack being TRRS for headsets with an integral mic, it didn't work well. This adapter plugs into a female TRRS jack and separates the TRS headphones from the mic, and it works perfectly.So my old headphones my brother is borrowing for his playstation ? so I had to use my pc headset but I wanted to play on my playstation. See the problem.But since I bought this , it works surprisingly well!I have a msi gaming headset for pc and this mini mic splitter works well for mixing headset to playstation so thank you!Now I don't have to buy a new headset just for the playstationAnd I like how it shows pink and green easier to check which is mic and which is headset anywho let's see how it is a yr from now
