can I connect multiple bluetooth devices, to an IOS device

Hi I have a Logitech Ultrathin keyboard cover, for the new IPad. I'm using the keyboard, all the time my IPad is in use. And sometimes I want to connect my Bluedio R+ bluetooth stereo headset, with bluetooth 4.0 NFC technology. So my question is can I connect both of my external bluetooth devices, at th same time?

Best Regards Alican!
