Review on Fosi Audio BT05 Bluetooth 5.0 Transmitter & Receiver - Digital Optical and 3.5mm Wireless Audio Adapter for TV, Home Stereo System, Car, Nintendo Switch - Supports aptX HD/Low Latency by Justin Zilinskas

Purchased to transmit Firestick BY sound to hardwire speakers with volume control. Works great in every way. Note: I need this for the entertainment system in my hot tub. I would give 5 stars if the developer/manufacturer included a remote control for volume control. Touching electronic devices in the water is not acceptable. So I stick with setting the sound to a comfortable STATIC level, hoping that the medium chosen is within that comfortable setting.
