Package Included:
It isn't the earphones that act as an antenna - it's the leads leading to the earphones. You can check this out for yourself by listening to an FM station and raising or lowering the leads - the signal will get either stronger or weaker/distorted. There's a simple (probably capacitive) coupling from one of the lead wires, to the RF side of the Walkman or whatever you have. The coil inside the earpiece is the earpiece's 'miniature speaker' coil.
You should consider the tonal quality. I t is very important for the earphone.
The headphone has the band that goes over or behind the head. While the earphones go directly on or in the ear without the band.
