Gear Ties, by Nite Ize, are one of the simplest, most useful little gadgets I’ve encountered lately. I picked up a 4 pack on a whim one day, and have since picked up at least half a dozen more.
Gear Ties are simply a thick, bendy wire coated in a grippy rubber. They hold their shape, which means they don’t need to be twisted together like twist ties. You just wrap them around cabling, and they stay. The grippy rubber holds cables nicely. They are super great at headphone management, and for organizing the typical geek bag, with myriad USB, power, and network cables. They are a lot more durable and reusable than the average twist tie, and their semi-rigid structure makes them a lot more useful. They certainly beat trying to coil a cable around itself, which can result in some ugly shape retention and/or cable damage.
They come in a variety of lengths, but thus far I only have them in 3” and 6”. 3” is perfect for headphones, short USB cables, iPhone cables, etc. Network cables, longer USB cables, and power cables will probably require a 6-incher.
If you’re like me and you’re day-to-day life usually involves a plethora of cables, you should give them a look.
