It is very good, meaning it does its job, but it won't last long because it has a very thin and sensitive, I can say, cable... So be careful

Good product without exceptional quality but not bad either. However, the main reason I am writing this review is to save money for someone who was looking for the same thing as me. 99% of the splitters break the microphone from the headphones. They do not clone the sound into 2. If you want it for this function, this product is not suitable for you. I couldn't find any in Greece and I searched abroad. In general, you should look for a 4-pin to 4-pin connection instead of a 4-pin to 3-pin.
