The included bases are labeled with what specific device they fit. These devices include the iPod (Large and small 5th generations, large and small 4th generations, mini and nano), the Zune and a generic insert. These loosely fit on the device (as long as no case is on) and are sandwiched between the transmitter and the device. It basically makes it so that the transmitter can't spin around. However, these bases don't have to be attached for the transmitter to work and I found myself not using them, so that I could switch the transmitter with ease, between my ipod, laptop and computer.
The charger is also simple. On one end there is the wall outlet and on the other end it splits into two identical connectors, so that you can charge the headphones and the transmitter at the same time. When the headphones and transmitter are plugged in, the connector area glows orange while it's charging and then turns off when they finish charging.
The instruction pamphlet is very detailed and walks the user through the basics of using the headphones. This includes connecting the device, charging the device and attaching the transmitter to the MP3 player of your choice. It also goes over what the different color lights mean and how to troubleshoot the device.
The installation procedure is very simple. Just plug the transmitter in and hold down the connect button until the light begins to blink red. Then, hold down the headset connect button until it blinks red. After a few moments, both lights turn blue and the audio starts pumping. Be sure, however, that the volume is at an appropriate level the first time you use it. It starts on the minimum volume setting, so it might sound like nothing is coming through at first.
There is also an undocumented feature that I found after 'googling' around. This "hidden feature" allows the headset to connect to any device that has Bluetooth with the A2DP profile. The A2DP profile is what allows stereo audio to be sent to the headphones, so it is necessary for the headphones to work. To access this feature, all that has to be done is to hold down the connect button on the headphones for around 15 seconds. The light will start flashing blue and red and the headphones will become discoverable and will be able to pair with other devices. I was able to find and pair the headphones on both my MacBook Pro and my LG VX8300, but neither support the A2DP profile at the time of this writing, so I was unable to test to see if they work this way. If you want to go back to using the headphones with the included transmitter, you have to set the headphones back into discoverable mode while the transmitter is trying to connect. If all goes right, they will both pair up and allow you to listen to music using the included transmitter again.
