Yes. I know that if I use a Bluetooth headset or a normal headset is easier. But I wish to use these as they are comfortable and have clear sound. About the battery, that is not a big problem. I have made an external power supply that I can carry with my N900 so I can power external 2.5" HDDs. The problem is the drivers for the headset. I do not know how to add them to the kernel or where they are supposed to be. Keyboards, mice and Ethernet adapters have been successfully connected and recognized by the N900 by installing some drivers into the kernel. I wish that some one would help me.
