MillSO Headphone Splitter for Computer CTIA 3.5mm TRRS Female to 2 TRS Male

This was exactly what I needed. I just bought a new pc and my head set/mic wouldn't work. I was scratching my head. Found out that you need a splitter. This splitter plugged in and worked right away no issues with connectivity. I love how easy the set up. Its also a perfect size that wont cause too much wire clutter. 5/5 would recommend to anyone having issues with their headset/mic connection like I did.

If you live in the US and need an adapter for any headset with a mic this item should work. There are two different types of audio cable plugs CTIA and OMPT formats. What this means is there is a difference between the plugs at the end of your wire for your headset. Here is a snipet from google explaining the two: There are different types of 3.5mm TRRS smartphone headsets and they are not compatible with each other. The most common issue that causes compatibility issues is the number of conductor points on the headset and what they are connected to (i.e. pinout), but the signalling arrangement (i.e. the way remote controls work) is also important. Modern smartphone typically use smartphone headsets with four conductor points (the "bands" that you can see on a connector). In almost all cases two points are used for audio out (stereo), one for the microphone, and one for signalling (e.g. to end a call). However, these points are not always used in the same way, or in the same order. There are two common arrangement for a four conductor point headset. The first, known as American Headset Jack (AHJ) standard or sometimes CTIA, has the microphone connector point on the sleeve end, with the signalling (or ground) connector on the second ring. This arrangement is used by most newer smartphones. Apple uses a similar connector arrangement, but uses a non-standard microphone and control signalling method. The second common arrangement is the OMTP standard. It has the signalling connector (ground) next to the sleeve, with the microphone connector on the second ring. This is the reverse of the AHJ arrangement. It is used by older smartphones. So to test if this adapter will work for your PC, first you need to find a newer android phone, plug your headset into it and listen to a stereo video on Youtube, or some music that you know is in stereo format. IF you can hear out of both ear pieces and the music or video is balanced in both ears this adapter WILL work for your headset for your PC. I found that way to test from doing extensive research on the two formats through Google. And man the cord is braided! another bonus if you're worried about it becoming worn or getting nicked and damaged. Overall I am very happy with this and would and will buy it again when I need to.

The braided cord feels much more durable than some of the other options on the market. The compact size makes it easy to leave on the PC as a poet that doesnt get in the way. Ive used these front and rear mounted on a PC, and have not had any issue with signal loss or degradation. We also have a headset that has a reverse wired plug, and the ability to swap the Jacks on this in reverse makes it a versatile option.

I bought this so that I could use my Apple headset with a Zoom H6 audio recorder. And it works with a few caveats. I noticed that some of the reviews indicated that it doesn't work with one headset or another, but I'm wondering if those people are aware that condenser microphones require power, be it from a battery compartment that is part of the microphone, or via phantom power or plug in power from the connected device. In the case of the Apple headset, power normally comes from an iDevice via plug in power. In my case, the Zoom H6 can provide plug-in power. This would be a requirement with any cable or adapter. In any case, it works - I can hear sound from the Zoom via the headset and I can also hear my own voice from the headset mic. It may be worth mentioning that this particular cable is a little bit shorter than ideal for the Zoom H6, since the headphone jack is near the bottom of the left side and the mic input is at the upper right, on the X/Y capsule. It reaches, but one has to either run the cable under the recorder, or over the top of it. I attached a photo so you can see what I mean. That's not really a knock against this adapter, unless one intends to use it for exactly the same purpose, and even then, it is workable. As for quality, when the headset is the only thing connected to the H6, that audio quality is quite good. Much better than one might expect after hearing the same headset used with for a phone call from an iPhone. It is as good as some dedicated lav/lapel mics that I have. There is no audible hum, although Apple's mic does have some self-noise, again, similar to some sub $100 lavaliere mics. I believe that one could reasonably use a similar setup for any number of applications and that 99 percent of listeners would think it sounded great. With that said, there is some cross-talk/bleed between the headset and the microphone. If I max out both the mic gain and the headphone volume on the Zoom H6, it actually causes feedback. Keeping in mind that there is a lot of gain going on when I do that. I can hear my own breath quite loudly, so the levels are way beyond anything "normal". Other reviewers have stated that this adapter causes bleed-through with their headset, but I'm not sure that it's fair to blame the adapter because I have used this same headset with the Rode Rec app on my iPhone (and thus, no adapters), and it is possible to cause feedback with that setup as well. So I would conclude that most, if not all of the cross-talk/bleed-though/feedback with this particular headset happens within the headset itself. I would expect differing results with other headsets. And then the shielding issue that some have mentioned. If I connect my digital piano to the H6 at the same time as the headset, I then hear some hum. It's not a lot of hum, but it's there. If I handle the TRRS jack on the adapter cable, it then hums much louder. It's not clear to me exactly what is taking place, but I can only assume that the piano connection exposes the recorder to the AC lines in some way, although, to be clear, there is zero hum when the adapter/headset combination is not connected. For example, if I connect the piano and my iPhone at the same time, that does not cause any hum at all. And other self-powered microphones plugged directly into the H6 also cause no hum. I have a working theory that it has something to do with the CTIA standard itself, because contrary to good engineering practice, that standard puts the mic line on the shell of the connector, which by all logic, is where the shield should be. The only way that one could effectively shield a CTIA connectors would be to use a secondary shield around the entire connector body, which is something that I have not yet seen done. Interestingly, the competing OMTP standard does, in fact, make the shell ground, but Apple has traditionally gone out of their way to buck any and all industry standards, so it's not too surprising that they didn't adopt OMTP. One can only wonder why others followed. If I'm right, then all CTIA-based microphones are going to be prone to hum, which would be no fault of this adapter. One could argue that MillSO could have come up with a way to provide shielding, but at the same time, it's not hard to imagine that they would just go with the standard, even though it may have a tragic flaw. Apple has since abandoned their own standard in favor of Lightning, yet another proprietary standard, and most recently, now that the world has purchased untold millions of dollar worth of Lightning adapters, they appear to be moving toward USB-C, which is bound to be the first time that Apple has ever adopted an existing industry standard. One might applaud if it were not for the investment in Lightning. None of that speaks to the needs of any serious audio production work, but it certainly will muddy the waters for headphone and headset makers. And I have not offered a complete answer as to the quality of this adapter. All I can offer at this time is that I plan to try building my own. We have a cable shop here, so I am wondering if we can do a better job with using off-the-shelf components, but my initial searches for shielded TRRS jacks did not turn anything up. FWIW, I intend to use this adapter for a while and see if the hum is a problem in a real-world recording. I think it may be okay, and beyond that, I’m not sure that any other adapter would be any better. Most of the sellers on Amazon aren’t even willing to commit to the CTIA standard, let alone reveal any technical details like shielding, so while this adapter may be imperfect, it may also be as good as one can easily get.

When I had the opportunity to get my first good gaming computer I was eccstatic but then the nightmare of bluetooth headsets and ear peices drove me to get some wired turtle beaches only to get home and boom, they aren't usb. well this lil device was all i needed and the 2 day delivery made me a happy old man again. paired it off later with an aux cord extender and still sounds amazing.

Plugged it together once worked, unplugged it and plugged back together and one side won't work. Nothing visibly wrong showing. Returning it appears well made molded ends and braided cable, something internal Update: very quick refund and follow-up e-mail from vendor regarding product. I received new one and its the same. Maybe my misunderstanding of how it would work or something missing on product description or still a defect. I wasn't using a microphone, wanted to use it to have two separate audio feeds to my radio so as to have a choice of audio feeds, not simultaneously but seperately. (Iphone (when using GPS) vs Ipod (when not using GPS ) via cassette deck adapter in car. ( I know i could just use audio from Iphone, but phone gets to much use during day to run battery down playing music while driving. When I'm using GPS I can use Iphone for music when I'm running GPS and allows Iphone GPS to interrupt Iphone music for turn by turn directions. Wanted to save alot of plugging unplugging when I switched between the two Iphone vs Ipod. Anyways found having female plug from this adapter fully plugged with male plug from cassette adapter it would only accept output from one lead. Found by partially plugging female connector into cassette adapter connector about 3/4 engaged it would then feed both audio input signals from each male plug.??? Made up a spacer out of tubing and electrical tape connectors to maintain connector position and all is good. Kudos to vendor for follow-up for what is an inexpensive product, As said earlier is well made braided lines well moulded plugs. Although won't be doing it they look like they can take some flexing and pulling.

Who knew such a small piece of equipment could save me so much money!? I didn't! Instead of having to buy a mic and headset seperate, I was able to buy this and use my gaming headset like usual rather than spending a ton more money! It does seem to make me sound quieter but thankfully volume adjustment is a thing! Its about the same thickness as your typical gaming headset cord, and over all the cable function is exactly what I was needing! No issues with the flexibility or connectivity of it either!

It sort of worked for connecting earphones to my computer to use as a microphone. Not ideal though.

This is a very inexpensive, medium weight build item. Worked out of the box.

The MillSO Headset Adapter works exactly as expected. The 3.5mm audio jack provides clear sound quality with no static or interference, and the 3.3-foot length is perfect—long enough for comfortable use without being bulky. It’s well-built, sturdy, and compatible with my headset and devices without any issues. Great value for the price and very reliable for everyday use. Highly recommended.

Worked as described and decent quality construction.

Works as described.

Crap. Doesn’t work. Avoid. Wasted my money and time
