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? It certainly looks like it..."

Strange use of terms.

No phone uses magnets and induction?

I can think of a device in a phone that does.

The idea is that a coil of wire (known as an "inductor") creates a magnetic field due to an electric current that varies in strength (this is known as an "electromagnet"), which then attracts and repels it, along with a cone designed to move sound, from a permanent magnet. In other words, the movement of the electromagnet moves the cone, which moves the air to create sound. Clever isn't it? Modern, perhaps? The whole mechanism is currently known as a "speaker."

I'm sure that this is neat and modern, but the naming scheme leaves something to be desired. What does "magnetic induction" mean in this case?
