The hole would not completely fit the apple earbud cable. Moving a tiny bit would cause the sound to stop working.

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

So far have no complaints, have only been using for one day and thus far has worked just as described in Amazon. So far I have to say its a great product and will definitely buy again. Thank you, I have been unable to use my computer to view videos because part off the jack to my head phones broke in the audio jack. It broke before it connected so am able to use this new jack with my new head phones... Thank you... It is a great product and highly recommend purchasing one if you need one...

***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.

Did what I bought it for. Got my sound working.

Used this to plug my Bose laptop speakers into a docking hub at work. Noticeable better sound than straight out of the laptop internal sound card, and plugging in ONE thing to run multiple monitors and speakers is convenient as my laptop is constantly in and out of office with me. If you need one, just buy it.

it does makes a pop sound at first not a big deal good deal

glad it works since the audio jack on my laptop no longer works.. Cable adds extra protection from pulling out from computer

I use this USB-to-3.5mm headphone adapter to plug my headphones into the USB ports in my monitor placed on top of my desk. The headphone cables are too short to reach my computer on the floor and still allow me enough length to move about comfortably. My headphones worked right away without any kind of setup needed. I am running Windows 10 OS. That sound quality for the speakers and microphone in my headphones appears to be equivalent whether I am using this adapter or plugged in directly to the computers 3.5 audio jack. The blue anodized aluminum connectors are a nice finish. The 3.5 mm connector has a logo indicating it can be used for both audio in (microphone) or out (headphones, etc). I would definitely buy this adapter again.

My son accidentally broke off the tip of his headphones inside the jack of his laptop. We tried every trick in the book (pliers, tweezers, picks, super glue, etc.) to get the broken piece out of the jack. Nothing worked. This USB jack adapter was a cheap, high quality solution that totally saved the day. It worked immediately, and the sound quality is no different than the headphone jack. Definitely would buy again.
