In the box, you'll find the headset itself, a mini CD with drivers for the USB soundcard, the USB soundcard, a sticker, and the manual. The soundcard has a USB header on one end, and microphone and audio ports on the other. The whole device is very compact, and has about 8” of rubber cabling.
Midway down the main cable, which is sleeved in a very classy woven cloth, there is a tie-clip control. From here, you can control not only the volume of the headset, but the transmit level of the microphone. While there is little difference between high and low for the microphone, the mute function works very well. Further down the main cable, the leads split into microphone and headphone. These first leads would most likely be used with the USB soundcard, which adds an extra ~8” to the cord length, whereas the included extensions would be necessary for reaching behind a case, especially one below your desk.
