After trying a number of different adhesive cord-management products, I do like all I've tried. These? given the range of girth that zip ties can work over, these are the most versatile. You can bundle and anchor any number of audio or electric cables in almost any size you are likely to find around the house. They do not make flat arrays of cables, though and some of the other products may be a bit more aesthetically pleasing. These don't look bad, they look practical, and if you place them in discreet places, it just doesn't matter.
