▲ 68 ▼ What is this wire for? (www.imagenetz.de) submitted 2 years ago by Slow@lemmy.today to c/asklemmy@lemmy.world 18 comments fedilink hide all child comments At one end of the wire is a 3.5 mm Jack plug. On the other end of the wire is presumably a glass LED. When connected to the phone, nothing happens. The LED does not start to glow. Also, this wire doesn't work as a microphone. It's also not an earpiece. What is it for?
