Testing a Hearing Aid Computer Peripheral without a hearing aid?

[ThrowinCards]

I have a few Phonak EasyCall 2's as well as a few iCube 2's and I am wondering if there is any way that I can test if these work without hearing aids so I can sell them without customers returning them? Does anyone know how to do this?

the Phonaks use Bluetooth.

Maybe a Bluetooth Speaker..... may have to test the pairing.
