Good quality
Size: 2 Pairs
These are nice connectors that I bought for some electronic box to record my vinyl and cassette collection onto my new desktop computer. I needed a second set of wires to go to a pair of JBL l100s so that I can hear what I'm recording I guess. This box I'm speaking of was recommended by Google Gemini and I can't get it to update so don't know what to do now. Also because of Gemini, I ordered HDMI cables to replace my 10-year-old ones and bought this brand and forgot to use the 10% discount that they offered. The HDMI cables are really great too
