Hello, I have been looking at getting a pc headset for some time after my Andrea one gave up the ghost. I have looked at lots of options including the fatal1ty headsets and all of them seem to have fairly good reviews. However I am purchasing a pair of Sennheiser HD 439s fairly soon and would like to use these as my actual headphones as they are great. Is there a good microphone I can either clip onto them or a desk microphone I can use. I am limited by my budget of £30 however. Thanks
