Magnetic Induction Technology Headset Reviewed

Semi-Anonymous Coward writes "The first review of a wireless headset using Magnetic Induction technolgy has been posted at mobile technology website MobileBurn. The reviewer mentions that the technology provides almost 'crystal clear' phone conversations, which is better than most Bluetooth headsets he has used. The magnetic induction technology creates a 'bubble' around the user which increases the security of their communications. Is this the replacement for Bluetooth in Audio applications?

The disadvantage of course is the short range--the device won't work far outside the loop; with this product (I doubt they instruct the user to run a wire all around the office) the range is only a couple meters--perfect for sitting at a desk without getting tangled, but no good for walking around the house.

    The "magnetic bubble ensures privacy" argument is a strange one; the only impediment to eavesdroppers is that couple-meters limited range on the (carrierless) signal. It protects privacy in the same way whispering would, but I would not exactly call it a selling point for those who need a secure line.
