The FM system can easily operate in many environments with battery power.
It is thus mobile and does not usually require a sound expert for it to work properly.
The listener with the hearing loss carries a receiver and an earpiece.
Another wireless system is the audio induction loop which permits the listener with hearing loss to be free of wearing a receiver provided that the listener has a hearing aid or cochlear implant processor with an accessory called a " telecoil ".
If the listener does not have a telecoil, then he or she must carry a receiver with an earpiece.
