I really hate leaving negative reviews, but there's nothing else I can do with this one. The splitter absolutely just did not work for me. I even made sure to remove my phone case to make sure it was plugged in all the way and nice and tight. But when I plugged my Apple Earphones to the splitter, the sound came through the phone speaker rather than the earphones, as if I had no earphones plugged in. I tried and tried. I removed it and replugged it many times. It just wouldn't work. Perhaps I happened to get a defective one.
