Review on Enhanced Bluetooth 5.0 Transmitter Receiver: Optimal Range for PC Audio, Home Stereo Speakers, Headphones - aptX Low Latency, Digital Optical, 3.5mm AUX, RCA Supported by Fred Griffin

Seems to be a common model that goes under different names. I have one and it works quite well on the receiver side as it is connected to my stereo. There are some features but it works quite well and is the lowest price point for those with the feature sets I wanted like low latency, aptX etc. I never tried the "Transfer" mode as it is for didn't work for me. See pictures of the supplied manual. Can help you decide if this will work for you.
