Long enough line for the person of average size and height; ABS material makes it not tangle like thinner cords; wires didn't get in way too much with 2 clips. Clear audio both via receiving the in-ear speaker and transmitting via the mic; acoustic tube with 150Ohm speaker impedance makes it better in noisy conditions. Fits snugly in ear and doesn't fall out with easy access to hook up;an additional ear plug to replace the original one if it gets dirty or if you loose it ;suitable for both left and right ears. Solid piece of equipment; hold up to your workers’ abuse day after day;PTT button is easy enough to find and press;new metal cap on tube connection make it fastened. Make your security team look very professional; you can do things without people hearing you; hide it under your shirt and you're good to go;pretty much invisible to the public.
