It comes very well packed with enough supplies such as rechargeable batteries, different adaptable taken to the USA, Australia, France and England, there is a very detailed manual + explanatory cd in 15 languages .
First it is not always easy to make the settings via the optical cable from the PC but that if it knows there is a little faster, the sound is different when using the jack cable but this is not that setting of the question.
The base is not bulky and lightweight.
The headset and the base on settings buttons are easy to use and provides a high level of listening and more when listening to music on PC and one call via skype music automatically comes down to hear best conversation what was feasible via a small downloadable software.
Please do not use anything other than rechargeable batteries when they fournient will not be good because they are recharged as soon as we put the helmet on its base.
My 19 year old son adores and leaves the more so it is comfortable it really is a must helmets.
