The sound quality is decent, it plugs right into my amp. Bought my son a mini strat for christmas and a distortion pedal.

These are much heavier and more durable. Solid built, compares well to name brands. One curiosity is that they do not have heatshrink tubing around at the ends of the plugs.

Seems to be a design problem, since the failure is usually that either the tip or ring disconnects.
