My sub kept randomly emitting a low hum, sometimes during use and sometimes when it was in standby mode. I thought it was a problem with the sub. Then I started wiggling the wires. When I did that, I could make the sub hum all the time. I got a new RCA wire from RadioShack. No such problems. What do you expect at $1.29? My other monoprice items work great.
Just exactly what the description stated and very nice quality. It's super inexpensive and it's nice when you just need to buy bulk. I bought it mainly to connect my reel to reel to my mixer, and it works great! Would definitely recommend.
