Seems like good build quality. I like how the cable tightens onto the rca jack for a tight fit that won't come loose and will fit snug on a variety of rca jacks (which ought to be, but often aren't the same size).
Braided jacket is a nice touch.
I wish the ends were color coded. Both ends have red rings. It would be nice if one of those were white. I almost thought it was a mistake, but it matches the pictures.
I purchased these to connect my preamp to my AV receiver to run my home theater system, and they have been incredible. Extremely well made, these things are solid. Amazing connection at the source, strong but flexible cables, and look pretty cool as well!
For the price, as always with Monoprice, there is no better option out there!
Pros: -look and feel of connectors is premium and excellent -very durable in all appearances
Cons: -Onix series cables are a bit stiff -identical to #21678, it's just two of them held together with two pieces of heatshrink -$4 price increase over buying two #21678, and all you get is 2" of heatshrink -I'm a little embarrassed to have had to buy this just to find that out
Just buy two 21678 and get your own heashrink instead
