There are two steps to streaming audio with Bluetooth devices - Pairing and Connecting.
You can Pair one source (iPod, iPhone, iPad, Android, etc.) to multiple Soundfreaqs, but you can only Connect and stream audio to one Soundfreaq at a time.
Similarly, one Soundfreaq can be Paired to multiple sources (iPod, iPhone, iPad, Android, etc.), but you can only Connect and stream audio from one source at a time.
This issue arises when one device is already Paired and Connected with your Soundfreaq and therefore the second device can't see it.
You can verify this because the indicator light on the Soundfreaq will be blinking slowly, indicating it is Connected.
Turn off the Bluetooth on your first device and then proceed with pairing the second device as usual.
If a device is not Connecting as expected, it is usually because another one is already Connected.
