This TC35I adapter consists of a female 3.5mm jack connector and a Lightning male connector. It will allow you to connect a 3.5mm Jack to an Apple device with only a Lightning connector, as it is the case on the latest iPhone. The components are integrated in a compact and robust 316 stainless steel case. The TC35I automatically detects and activates when a headset is connected to it. The adapter can also be used with headphones/headsets with built-in controls and microphones.
