Right. I've used a headset while connected to a Redfly. Those are different classes of devices. But you can't use two Bluetooth headsets simultaneously on the same call. Since I suspect the watch/bracelet probably uses the headset or handsfree profile to get the caller ID information, they can't both be connected to the phone during a call at the same time. Every time I take a call with my BT headset, my watch disconnects. Same problem as OP.
