Hi, I just picked a pair of CTEK Performance Series headphones. Model CTEK-BTH1. They look brand new. I'd like to find an instruction manual for them so I can figure out the features. They seem to have an AM/FM tuner and micro SD card slot besides Bluetooth. The company that is using the CTEK name now doesn't know anything about them. I sent them some pictures of them. I'll try to attach a picture of them to this post. Any information would be greatly appreciated. Thanks, Jim
