The Sennheiser EW-D SKM COLOR CODING offers a set of 16 color-coded indicators that magnetically attach on EW-D SKM wireless handheld transmitters. By matching the color on your transmitter to the color on your receiver you can quickly identify and keep track of up to 16 EW-D wireless microphone channels.
These work great and as you would expect but just be aware that there are 16 individual colors and no pairs.
These color tags fit perfectly. Having used some previous generation rings I like these tags much better, they slide on and off purposefully and don't feel like they will ever come off accidentally. I am also a fan of the fact that the color is at the end of the stem where the singer has a much harder time covering it up.
