***UPDATE*** 2021/03/20 A representative from Millso reached out to me to try to fix the issue. They issued me a replacement adapter and I have yet to find out if it is experiencing the same problem as the original. Kudos to them for trying to fix things. Im adding a star for support and will update again when I have a chance to review the new unit. --Original review-- I wanted to find a TRRS headphone with mic adapter for use with Windows computers. I purchased this thinking that it would operate like youd expect... Listen to Zoom/Skype/WebEx calls and talk back to everyone using a headsets built in in-line mic. While technically it does work, it has an annoying echo where the incoming caller audio that should be going only to your ears is brought back into the input channel and then sent out to everyone on the call. The result is that when someone other than me speaks, my system takes their audio and pushes it back over the call. Its kind of like being in a small canyon. The echo is probably 100-100ms in its delay and it happens multiple times as the call audio that I generated then comes back and then goes out again. Very annoying. I did pull my headphones out of the equation and even without headphones plugged in at all, it echoes the incoming audio destined for headphones back into the mic input. Again, it does this even when the headphones are disconnected. I tried this in multiple software applications. I even loaded up an Ableton session (a DAW) and setup an overdub. Listening to sealed in-ear headphones with an inline mic. The Ableton recording from the mic was not clean and contained a clear audible copy of what I was hearing in my in-ears. It was about -20db down from full, but it was there clear as day. This wasnt sound from my earphone travelling back into the mic. It was full bandwidth audio recorded back into the session somehow from the adapter. It did this with the headphones disconnected entirely. If I set the audio to output into something other than this adapter, the problem went away, but that defeats the purpose of having a headset mic + headphone adapter. On top of all of this, the mic preamp is very noisy. I suppose its a bunch to ask that a usb plug sized device could have a decent mic preamp. This thing is tiny. As a headphone adapter, it sounds fine, so 2 stars for that. Im returning this as it wont work for what I need it for.

Paired this with a KVM switch to hookup 4 computers to one common monitor, keyboard and set of USB ports. Used this on the USB port to share one set of speakers for the audio output of each computer. Worked for both Mac and PC.

Adapter worked fine for about 2 weeks of very light use, then stopped working out of the blue. My cable must be faulty, as any machine I plug it into gets a very faint static signal and thats it. It was nice while it lasted, but it should have lasted more than such a brief period of time.

Its okay, but when you have limited usb ports on motherboard, might find it dosent draw enough power for headphones and mic. This is the problem i ran into.

I purchased this to use when I want to listen to music on my computer using headphones. Prior to using this device I plugged the headphones into the port on my desktop speakers which works fine but is just not convenient. What I wanted and now have, is a way to switch from my desktop speakers to the headphones by using the sound setting on the task-bar so I dont need to plug and unplug the headphones. Why, cause I am lazy and want to be able to make the change while I have my feet up on the desk with my keyboard in my lap. I was not sure this device would do that based on the description, but I asked a question and someone confirmed it does work that way - thank you for that, which it does. It now shows up in the sound setting like a device which I was able to rename to headphones so I can easily switch my output device using the task bar sounds icon. As for the sound quality, it sounds about the same to me regardless if the headphones are plugged into the jack on the speakers, directly into the output jack on the motherboard or the new jack adapter. Its appears to be a well made device too. I purchased the longer cord so its not braided like the shorter version, but its a quality material that is soft and flexible. The extra length allowed me to wrap the cord around the base of one monitor stand to its always available for easy access. Very pleased with this purchase and have no issue recommending it for anyone who plans to use it the same way I have described.

It seems that customer service and I had a miss communication problem, but Gina took care of everything. Ordering a product is one thing, but how one is treated after the deal is done, says much more. Good product for the price and people that stand behind the product. Turned out to be a positive experience.

Bought this after my audio jack was damage on my laptop. Works perfectly and isnt too long where it becomes annoying. Recommend if youre in a similar situation as me.

Tried this instead of buying a new sound card as my PC sound stopped working. What a great way to save $30. I use it as an audio output not input. Sound quality is great. Works with windows 10 and no issues installing. Just plugged in and it worked

Working good

It just works. I cant say anything about the sound quality because I have it hooked up to terrible speakers, but it fixed the problem I was having with my horrible surface book 2 dock which would not output sound at a listenable volume. This fixed the problem and is almost indistinguishable from a normal 1/8 inch stereo extension cord. So yay!
