bluetooth audio receiver with 'relay outputs'

[Opcom]

I'm looking for a simple bluetooth audio receiver with a few 'relay outputs' meaning opoen collector, small relays, whatever. It should have an app so that from a phone I can push high quality audio files to it, and use the app to set audio level and select functions to which the relays will be connected. Anyone know of something like this?

I've been looking for a Bluetooth "transceiver" for some time. A device that can receive (mic) audio from my noise cancelling Bluetooth earpiece and provide a line out, say @ -10db. to feed the transmitter.  This transceiver should also have a line input so I can take low level audio from the radio and feed it to the earpiece via Bluetooth. Anyone know of such a device?

been looking through these.
Since they are stereo, it shouls be possible to encode a remote tone on one channel, but not for what I need to do. I need stereo.

Apparently apple iphone does not support aptX, but it does support AAC. These are the high quality low-latency codecs. Whatever BT product is to be bought should support what the paired thing (your earpiece etc.) supports. All support SBC which is the lowest-quality low-processing-power format.
