I'm looking to get some wireless headphones. I found these: http://www.amazon.com/exec/obidos/tg...onics&n=172282 and they look great for the price. I have Koss UR-20s now, they are great and have lasted almost 5 years.

I was at RadioShack and tried these: http://www.radioshack.com/product.as...5Fid=33%2D1196 which were great, but they do not have earmuff type headsets. They were also 900Mhz and there was 1 bleep per 10 seconds there, where it is full of interference.

I'm just wonder how much interference I would expect, I have 5 900Mhz cordless phones in the house I am at (Including one next to me.) Also, will this pick up from more then just my house? The RF range on those are 300 feet, the size of a football field! I would expect not since I assume that the frequency is different for phones and headphones?
