I've already discouraged 3 people from buying these . I am constantly required to reconnect with my devices; the bluetooth function only permits one device at a time. So if you're connected to your phone and want to use them on your tablet, you must physically disconnect from the phone 1st. If it's nearby great; if it's not you need to get and disconnect before you can use it on your device.... over and over again. It is quite inconvenient and time consuming. There is very little product support as well. I'm referred to product help but it doesn't work unless I'm connected. If you have a fix for this annoyance great; otherwise these are coming back!
