KINGTOP Headset Splitter, 3.5mm Headphone Mic Splitter Cable for Headset with Separate Stereo Audio & Microphone Jacks (Not for Dual Audio Jacks)

Like many people I'm sure you are working from home suddenly and may want better quality audio for your conference calls or interviews. I just wanted to get better audio quality over webex since it seems to handle Bluetooth particularly poorly at least on macOS.Anyway I bought this adapter recently and initially meant to buy a different brand which listed support for macs explicitly but it was out of stock and when looking for an alternative I didn't notice this one said it wouldn't work on a mac.You can tell it is made with good materials but when I initially plugged everything in the headphones worked fine but not the mic. I came to the product page and shook my head... Since I have a minor in music technology I figures I'd see if I could get it working anyway before exchanging it for something else.I'm using a mid 2015 15" MacBook pro, Sennheiser HD 650 headphones, and an antlion Mod MIC V4.The trick to getting the adapter to work for me was so silly I couldn't believe it.Here was the fix for me1. Plug in a standard pair of headphones with a TRS connection to the headhone jack on your mac (if you're unfamiliar with TRS that is a 3.5mm headphone connection with exactly two colored rings going around it. They are usually black, white or red).2. Unplug the headphones3. Plug in your headphones to this adapter then plug in your mic to the mic side of this adapter.4. Plug the adapter with the headphones and mic already connected on the other end.If you check your sound settings on your mac and everything worked you should now see that it says "External Microphone" and not "internal microphone"I hope that helps some of you out!

Works great with my Rode Video Mic Pro plugged directly into my Mac. Works great!

Purchased a BYECH UV-25X2 Mobile Ham Radio. Only problem is radio has headset jack on rear, not usual speaker jack. Plus it is wired backwards to US wiring standards. Struggled purchasing several adapters that the mfg said would work but didn't. Stumbled across an online review about the radio and a splitter that the person claimed works with eternal speaker on the UV-25X2 radio. Plugged this Y adapter into rear headset jack, then external speaker into the microphone plug on this adapter. Turned on radio and yes!!! It actually worked as I had read online. Even the mfg does not help with correct adapter which works. If you have a BTECH mobile radio, check the rear jack. You will see small headset icon, not speaker. Plug in this adapter, and external speaker to "mic" female on the adapter. Wonderful to be able to have a working external speaker in vehicle. Now I can turn it up loud when desired, without harming internal radio speaker! Excellent quality build and I like the flat wires, which take less space. Purchased 3 more for safe keeping as it took me 1 month to find a working adapter for this radio.

Working perfectly

KINGTOP, worked with my Audio headset, enabling me to continue to use, my headset another computer.

Good quality connectors - connecting the cable from my headset requires a reassuring amount of force and click indicating a strong connection that shouldn't be easily pulled out by accident.

I opted to tear into it, to better understand the failure, rather than return/replace it. I was just too curious about how such a simple cable failed. The polyethylene (not kidding, essentially hot glue) that the contacts are potted in is too soft for the application in the warm weather we are having. In my case the ground contact in the mic connector moved too much. I also discovered that they neglected any shielding---which explains why I was picking up noise depending on how the cables were lying. I'll try a brand-name cable next. Hopefully it will be wired correctly, shielded and reliable.Original review:My use cases: 1) Using my phone to record video with better sound; 2) Using my phone for audio recording 3) voice-over on my laptop; 4) VOIP with my studio headset.As hoped, this has the popular TRRS plug pinning that works well with mobile phones and laptops. That is [stereo out left+, stereo out right+, ground, mono mic+]. The stereo headphone jack is also standard, being a TRS with [left+, right+, ground]. What's odd is that the monaural microphone input is also a stereo TRS [mono mic+, mono mic+, ground]. In other words the tip and ring the the jack are both connected to your devices single mono mic input. The problem is that, electrically, whenever a mono mic or adapter is inserted into this stereo TRS jack, the ring contact inside of the jack touches the grounded sleeve of the microphone plug and there is no sound at all. To make this work with a conventional mono mic plug you will need something like a 3.5 mm TRS stereo plug to 3.5 mm TS mono jack adapter. Those adapters will connect the the tip and ring from this product's jack to your microphone's tip connection. I'm not sure if there exists mono mics with stereo connectors but that should work as well as long as any adapter is also stereo.

I have a pair of headphones and a separate lapel mic that I would like to connect to my laptop. Each of the headphones and the mic has a TRS male connector and the PC wants a single combined TRRS connector for audio. Most modern laptops are like that. This cable does the job. However.....If this cable is not so cheap I would have return it already. Feels very light and plastic. The connectors are all plastic. Not sure how long it will hold up. I am sure there ain't much copper in the cables/wires either since they are the flat type. The description says those flat cables is designed to prevent tangling. I don't think so since those cables are too short to get tangled anyway.All in all, a low price for a cheap cable. But it worked for me.
