The mic is cyrstal and your teammates will have no issue hearing your callouts. I had bought 1 pair and it worked so well, I bought a 2nd one. Tatsächlich steht auch auf den Etiketten 15 " und 26l. I’m very satisfied with this product and the amount of hooks that comes with it. They dont feel/look cheap or puny. Expensive and stopped working reliably a few months after buying. The camera is absolutely horrible. The trickiest part is "snapping" in the pads. But when the second one stopped working I realize that it wasn’t I that caused the malfunction. There is a random number stamped into the metal of this (part number Im assuming?).
