This headset splitter works very well when it comes to the audio component. It claims iPhone earphones are not compatible, however when I tested my iPhone earphones along with another pair of earphones, the stereo audio output was split fine, and quality of it was decent. It even worked well when connecting the splitter to a lightning-to-headphone jack adapter, as my iPhone 7 Plus does not have a 3.5mm headphone jack. The microphone of the iPhone earphones however, do not work. Depending on the earphones I used (all were 4 pole earphones), it seems not all are compatible with the splitter when it comes to microphone use and recording. When attempting to record a voice recording or video, some microphones work when just one set of earphones is connected to the splitter, but once two are connected, the microphone for the first set no longer works. I have a pair of earphones where its microphone definitely works every time with no issues, whereas other earphones that create different tones of feedback. However, it is not very often that you’ll need to use the microphone component of the splitter. It is mainly used to share and listen to music and movies. It would be convenient to use on the plane or in public transport, where you do not want to disturb others or if you cannot hear from the speakers of your device due to external noise, yet still want to be able to share and listen with another family member or friend. The cable appears strong and thick, however a tad chunky compared to others out there. It is still convenient to carry anywhere and everywhere on-the-go.
Bought this to run a soundbar and pc speakers from my computer. Works really well, no noticeable noise static, all around a really solid build. Cables are of decent thickness unlike the cheap stuff you order from china. would be easy to carry around if thats what your intent for purchase is. Highly recommend.
My cable came, and it had one plug for headphones and one for microphone. So it doesn't do the job of splitting one headphone cable to allow for two headphones to be plugged in. I was sent a replacement.
