A:AnswerThe app is Samsung Gear, I am hopeful it would be available for all android devices. The case these come in act as a charging station as well as a transfer station. Hooking these up with a micro USB connection will allow you to load music on both earbuds. The files show up independently in Windows as ICONX L and ICONX R (or something close to that, just pay attention to the titles for the file space)
A:AnswerThese are Bluetooth Earbuds which means you can pair them with any phone that has Bluetooth connectivity so yes you can listen to the music on your phone. As for the lanyard.. the Buds ear loops were not designed for that.
A:AnswerThis is apparently normal. I just don't close the case all the way. This disengages the buds from the contacts which allows the phones to sleep if not in use but it doesn't drain the case battery. The buds charge faster than the case. A bit of an inconvenience until Samsung fixes this.
