Review on 🎧 ZIOCOM Bluetooth 5.0 Transmitter Receiver for TV, aptX Low Latency Wireless Audio Adapter, 2-in-1 Dual Link, Built-in Battery, Optical/ 3.5mm AUX/ RCA Connection for TV, PC, Speaker, Home Stereo by Melody Young

I was hoping to use this device to extend the bluetooth range with my main computer for listening to music/YouTube/games at home. It worked fine the first time, redirecting the audio from my computer's line to bluetooth (no longer having to keep switching the audio output), but I found that while this allows for two devices, my lypertek truly wireless headphones do not properly paired both. Sides (left and stereo work well, but right alone doesn't work). Also, on the second day of use, I noticed an annoying hum from the audio that appeared to be coming from a USB plug (I had to switch power supplies). There is a reach. ok but definitely NOT 40 feet as advertised. Latency is pretty good with a quality headset (wish I knew what it uses). The device works quite well, but it would be better if: 1. There was even a tiny screen to show battery, ports, volume, etc. Ability to connect to more than two devices3. Actual on/off instead of holding and waiting4. Better shielded USB (hum?) 5. More variety
