Nice device straight out of the box. I installed it where I wanted to use it and tried to pair my LG Stylo 5 and it took 3-4 times to pair. I then tried connecting my wife's phone, a Samsung Galaxy S9, to it and it connected the first time. Now the device does not recognize my phone at all. I then hooked up a Marantz 3200 preamp to the unit and they seem to work well together. After about 2 hours they stopped liking each other and the sound started whistling. I thought it was my preamp. So I hooked it back up to my DC170 Marantz and it behaved as intended. At that moment, I decided to just leave it at my wife's phone. It likes to be paired with just one device. I hooked it up to my Toshiba flat screen TV and it was definitely a NO. The sound was terrible. I even switched the speakers but to no avail. Maybe I'm doing something wrong, but I doubt it.
