Hi Matt:
Yes this should pair with the Tao Tronics 4.1 Transmitter, I believe they have two models that will sink with a couple pair of receivers. You may have a problem with latency on one or both pair. Here is from their specs:
Pairs with 2 Devices: 2-in-1 Bluetooth 4.1 transmitter pairs with up to two Bluetooth receivers like headphones or speakers simultaneously; Note: aptX Low Latency does NOT support dual link mode. We are working on a new Bluetooth outdoor sub featuring connection for up to two pair of any speakers.
Stay tuned
