It works great, but not in the way I expected. For tech-savvy users, it is not an adapter. The device is essentially a mini Bluetooth device. When you connect it with the Lightning to the iPhone, it detects a Bluetooth headset and you connect it. It is not battery-operated; it is powered by the Lightning. You connect your wired headphones and they work normally. The Pause and Vol Up/Down buttons work correctly from Android headphones. The sound is satisfactory in quality and volume. Update: the rating drops to 3 stars because on calls, voices sound distorted as if it is Bluetooth with a weak signal. In music, it is OK, but in some songs, it still sounds strange.
