Review on 🔊 TROND TV Bluetooth V5.0 Transmitter and Receiver: Wireless Audio Adapter with AptX Low Latency, Optical TOSLINK and 3.5mm Connectivity - Pair with 2 Devices Simultaneously by Rosalio Zavala

So far so good! It took a few tries to pair it with my headphones, but once you understand the exact steps the manual is trying to give you, it's pretty easy! Press and hold for 3 seconds to turn on. You will see a flashing blue light. After that, double tap to enter pairing mode. You should see a light alternating between red and blue, which means you're in pairing mode. Connected with an analogue cable and also with an optical audio cable. The analog cable had a much deeper base and slightly more clarity than the optical audio cable. It might just be my desktop computer, but that's not a problem for me as I'm happy with the audio cable connection. I've connected and reconnected many times in transfer mode with no issues!
