BLE can't transmit data fast enough for audio. It maxes out at a few tens of kilobytes per second.

For audio, you need what's now called Bluetooth Classic. Unfortunately BT-C requires a vendor ID that you can only get as a dues-paying member of the Bluetooth Working Group. You pretty much have to scavenge audio Bluetooth hardware from off-the-shelf products.

Check out microchip's BM83 module. I think it will do exactly what you need! (even has built in battery charger!)

Finding hardware that can do it is no problem. Getting the license (in this case, the VID) to use the hardware is the hard part.

So, if my intent was to make a phone dialing device that also had a speakerphone (to connect to my iPhone) I'm outta luck?

If you want to build it from the ground up and don't feel like handing a few thousand dollars to the BT-WG, yeah.. pretty much. The rules of that product category are written for the benefit of the big players.

The most viable option is to scavenge BT-C hardware from off-the-shelf products and use that as part of a system you've built yourself. There are no laws or rules that prevent hijacking licensed hardware for purposes the manufacturer didn't intend.
