Review on 🔌 2-Pack CableCreation 3.5mm to RCA Cable 1.6ft, 3.5mm TRS Male to 2RCA Male Stereo Y Splitter Cord for Echo Dot, Smartphone, MP3, Tablet, Receiver, Car, Speaker, HDTV, etc. (0.48M) by Matt Welch

Purchased for use with Camp speaker system. We installed everything, everything works. When we plugged in an RCA cable and connected a music player to it, all we got was static. No big deal, they were cheap and that's 2 packs. So we glue the second cord. Same problem, just static. Finally, to avoid utter frustration, we connected a microphone to the music player to play low-quality music. At least the kids weren't picky about the sound quality. They just liked the music.
