POSUGEAR Headphone Mic Splitters Adapter, 3.5mm Male to 2 Dual 3.5mm Female Audio Mic Y Splitter Adapter Compatible with Phone, Laptop, PS4,Gaming Headset, External Microphone and MP3 players[CTIA ]

Bought this to enable vocal/instrument recording on my iPad via the headphone socket to allow me to hear my vocals and the sound recorded on the other tracks. Mainly to record into Blocs Wave. I have tested this with various mics and instruments and the sound quality is really impressive. Firstly the splitter is beautifully constructed and feels well made. The connections are tight, allowing great signal transfer, and each of the connectors is labelled to show either headphone or mic connection. It should be pointed out that this works most successfully with 3 pole jacks. It literally splits the mic and headphone connections on the iPad to enable recording and listening at the same time. Also any mic or instrument plugged into it needs it’s own power eg phantom power. I have used it successfully with a PC condenser mic but actually the best results have come using good quality lapel mics. Because it ultimately sits in a chain, there is always the danger of increased impedance if the chain has too many connections eg a mic passed through a mixer or processor before the splitter might induce worse results. Personally it’s best to keep it simple and use it as the seller advises. This is a nice piece of kit, and looks and feels professional.

I am using this to connect an external microphone to my MacBook Pro using the headphone jack. I would HIGHLY recommend it as a cheap work around for that application, and it is working wonders. Sometimes the mic isn’t recognised so I just unplug and plug it back in and it seems to do the trick. Absolutely definitely worth the price and seems well built and likely to last unlike some cables.

Wanted to use external mic for OnePlus 7t. Confusing product details but worked for me. It states in one part it doesn't work for TSR 2 pin and TSSR 4 pin. I have an external TSR 2 pin mic. However, in another part it states it does. If you have USB C you'll need a usb c to female jack and then plug in this adapter to the usb C adapter and attach the mic. The other thing is the mic only be works if the USB C to phone is plugged a particular way up. Also your app should support external mic audio e.g. open app which must be enabled. I've found some apps work automatically so it's trial and error and largely depends on the app. It doesn't work for OP 7T native camera app.

Needed this Ysplitter cable to allow me to use a microphone with my Macbook Air for Zoom meetings. Slight problem with this is that very presence of the jack plug in the computer socket disables the internal speaker as well. An external speaker must be used in the speaker socket of the splitter. Otherwise it works great. Vast improvement in sound quality in both the microphone and speaker depts. Pity everyone else I meet with on Zoom doesn't do the same.

Does exactly what I needed it to do. I was having trouble using an external microphone with my laptop which only has a 3.5mm jack input/output for headphones. I contacted the manufacturer of the microphone as they had included an email address for an adaptor if the microphone didn't work. I got sent a replacement which gave out a horrible squeal during recording and playback so I decided to take matters into my own hands and, after researching thoroughly, turns out it was as simple as splitting the channels to input (mic) and output (headphones) using this device. The 3 rings on the jack represent something called TRRC which is needed for input & output, rather than 2 rings which represents TRC, only allowing an output. Additionally, this adaptor has also allowed me to use my Samsung Galaxy S10+ with the externally microphone.

Couldn't get it to work. Dunno if I was using it wrong

This is really neat as the mic and headphone splits are clearly labeled. I can plug this into my Google Pixel 2 (with USB C adaptor) and it means I can turn my phone into an instant pro video camera for vlogging and interviews. I plug a lav mic or Rode shotgun mic in, plus my in-ear headphones for monitoring. I love stuff like this, just a simple, inexpensive cable can completely level up your setup. Quality is good and audio is transparent.

This does not support the external mic input on my M1 MacMini or my M1 Mac Book Pro 14 inch. I have tried a couple of microphones with no joy. Also the headphone audio quality suffers compared with plugging my headphones directly into the mac's socket (lower volume). I have no idea whether it's faulty or it just isn't compatible somehow, but I certainly won't be ordering a replacement! I did however find a solution to my needs in the form of the Sabrent USB Audio Adapter - (just look up AU-MMSC). This little device is available in USB A and C and costs only £2 more than this cable! The Sabrent gives you headphone out and line/mic input, so hands down so much better than this cable for me. I bought the USB-C version for my MacBook Pro 21 and it works flawlessly.
