Its everything someone with limited space needs: rack, j-cups and some options for expansion later on down the road should you so choose. So be patient. I use it with an IP phone at work and it worked well out of the box. These slippers are very comfortable and so soft I can feel how soft even when I have socks on. Opened the box, easily found the little cable inside the headband and attached it to the white cable that came with it and starting charging it (didnt have to press any button or anything else, just attach and plug it in). Also the coat doesnt appear to repel water any better. I like the fact that the sound is clear and blocks out background noises. My gaming headphones were too heavy to wear all day. These headphones have many more features than the pair they are replacing but what I find particularly useful is the microphone which allows you to make and receive phone calls on the move. I was hesitant to buy an entry level headset, but after using these a little over a month, I cant justify buying over priced ones.
