Review on GMCELL 2-in-1 Bluetooth 5.0 Adapter with 3.5mm Aux Jack for TV, PC, Speaker, Headphones, Car, Home Stereo - Wireless Transmitter & Receiver for Streaming Audio by Corey Holloway

I use this for video and e-drum set. The delay is so bad. Their delay is about 2 seconds, so it's like watching an old dubbed movie with subtitles where the voices don't match the mouth. Also tried using it for a drum set, the delay was so annoying you hit the drum and after 2 seconds you hear the sound. The worst thing is that the volume was so boring. I've paired it with a Bose Bluetooth kit and an iPod Pros kit with the same result. I think it's great for music but don't expect it to be loud. And forget about using it if latency is an issue. Doesn't work for TV or Roku Sound isn't compatible with video. Useless because nowadays we all want to watch videos with him.
