I haven't tried it, as I only use it to stream from my phone, but lifewire claims:

"The Logitech adapter can store up to eight different Bluetooth devices in its memory, and you can even have two of them connected to the receiver at once."

The also point out that it lacks modern audio codecs (e.g., aptX) for handling hi-res audio, but I've been satisfied with it.

The audio receiver can have one device plugged into it and up to 8 Bluetooth devices in its memory and two attached simultaneously.
