Call Wireless With Skype VoIP

I really use Skype very often to call for free with my friends and business partners local and long distance.
But what annoy me is that I used to need my headset and I could't leave my PC.
I own a wireless headset from Sennheiser which I bought a long time ago to hear my favorite music but i've not used it for many years because the accu was no more working. So I bought 3 new one on Ebay for some bucks.
And now I hear to videos and audios I download from the Internet when I'm leaving my office and go into the kitchen, bath or into my garden.
But this didn't helped me with my Skype calls.
Than I bought a bluetooth wireless USB adapter and plugged it into my pc, installed the driver and connected it to a microphone.
Now I have a really cheap wireless solution to talk via Skype with my friends and don't need to sit in front of my pc all the time.
