Lyric’s unique placement deep in the ear canal means it stays there for months at a time so you can hear 24 hours a day, 7 days a week. You can wear a Lyric hearing aid during your daily activities such as sleeping, showering, exercising, driving, attending the theatre or a concert, watching a film, using external headphones, talking on the phone. There are no daily hassles of insertion or removal and no batteries to change with Lyric.
