Excellent replacement for IE 900 stock cable

Awesome replacement for a terrible stock cable. More comfortable and no sound compromise

James K. (Madison, US)
quality cable for the IE600

I've tried both the stock IE600 cable and cables from other vendors and found that the Null Audio cables have less microphonics and have less of a memory effect (easier to wrap and unwrap). I don't buy into the idea that cables affect sound quality, but I do want a cable that looks good, is comfortable, and is easy to use, and this cable meets all of those criteria.
