***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.

Worked immediately after I plugged my ear buds into it. An easy solution for headphone jack on laptop not working.

I use this with my computer at work that is hooked to a docking station. Before using this I was having sound and mic quality issues on Teleconferences. Now these issues are gone.

I can not give a rating at this time because I am still working on trying it out. It works just fine!!

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.

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.

I don’t know if I got a faulty one or not but it had a wearied buzzing sound even after trying different ports

This works just as advertised.

I got this so I could use my gaming headset with both my PC and PS4 hooked up to a USB switch. It works perfectly and has fairly decent audio quality for less than ten dollars. It is limited to DVD Quality at 48000 Hz on Windows 10 however. This adapter also supports several Windows 10 enhancements such as Bass Boost, Loudness Equalization, and Virtual Surround which do help the sound quality. Not as good as the headphone jack on my computer, but the convenience of having USB is worth it.

Wish I would have bought this years ago! Use it with the Arama headset which is around $20 and was always incredible for use with my iPhone 6, most comfortable and good quality sound ever, does not cut out like some other cords. Recommended.
