aviatorhi, you have a valid point. I was discussing with my better half (she who holds the purse strings; both mine and her own!) and she suggested the same thing. However, boys being boys and wanting new toys, particularly as the cost can offset tax liabilities, I thought I would test the waters of advice.
SNS3Guppy, I found a thread in which you or someone else mentioned the QC-15 and would consider it. I overheard a colleague mentioning getting a new headset which was supposedly great but required the purchase of separate mic. I wonder if it was the QC-15? In any case, I recall he had problems with his new headset. I shall have to investigate further.
In the mean time the big green headset will do the job...
