Review on 🎧 ENVEL 3.5mm Jack Cable Headset Adapter Kit - CTIA Compatible for Laptop, Mac, PS4, Smartphone, Xbox One, Tablet - Earphone with Headphone/Microphone Simultaneously - Y Splitter Audio - 2 Female to 1 Male by Justin Pavelko

I bought two of these adapters because their listing says they allow me to 1) send a microphone signal to a device like my iPhone and 2) allow me to plug in separate headphones for stereo monitoring of the headphone output worked fine (ONLY IF YOU ARE USING A STEREO HEADSET - WILL NOT WORK WITH A 3 PINGER MOBILE HEADSET). The microphone input did not work properly and only worked after a lot of trial and error and only with a very specific microphone input. What a pain in the ass! This is not a plug and work adapter! I tried the adapter on the iPad and the same malfunction occurred. My trial and error has shown that this connector doesn't work for BOTH of the two devices I bought, so I know that not one of them was defective, but I believe this malfunction to be a design flaw. You may have to fix a lot of bugs to make it work or find the right microphone for it. Not quite the "universal" adapter I was hoping to find. Here's a little fix I did that I hope can help you. This microphone with a mono feed to the stereo input - it did not work. • I have several other microphones that I can connect to the stereo mini jack, including a lavalier microphone with a different power supply - none of them worked. THE ONLY MICROPHONES THAT WORK WITH THIS ARE THESE ADAPTERS ALREADY STARTED AS A TRRS (3 1/8 INCH RING IN) ADAPTED TO A STEREO INPUT! - Ringing devices (even if customized) designed to see the iPhone and iPad through the input to determine that a microphone is connected. Without using such an original 3-ring microphone, the device does not seem to recognize that the input is connected to the adapter .And THIS IS NOT THE ADAPTER FOR IT SHOULD IT DO? A SOURCE-INDEPENDENT SOUND DEVICE? So again, if you're not open to a lot of trial, error, and frustration, then this adapter is NOT for you. By the way, I went to the local electronics store. saved and bought the SAME type of adapter (a TRRS that splits into stereo audio in and stereo audio out) and it works fine WITH ALL the audio inputs I send through it. It really is plug and play and that's how I expected this adapter to work. Well, as the age old saying goes, if you buy invisible crap here at Revain, you get what you pay for!
