InSound Medical has launched its new hearing aid in Britain that is being touted as the first �invisible� hearing aid

A major drawback for the Lyric is its expensive price with the hearing aid available only on a subscription basis at over £100 per month.
Commenting before the launch of the machine in Britain, a company spokesman said, "Users need to visit their audiologist once every three to four months, whereupon Lyric is replaced with a new device. It is placed in the ear canal by a specially trained hearing aid audiologist, with no surgery or anaesthesia."
