Query: Great value, but not perfect

I DJ at local bars and small clubs on weekends. I've been using these cables for about 6 months now and they are certainly durable. The sound quality is excellent, but the tips tend to unscrew slowly overtime -- my right or left speaker has unexpectedly cut out multiple times as a result. It took me a while to realize that the issue was related to the tips being unscrewed. In any case, for budget cables, the sound quality is great and as long as you remember to tighten the tips before use, you'll be in good shape for a low price.
