Lyric from Phonak is the only true 100% invisible hearing aid available in the market. It sits approximately just 4mm from the ear drum making it virtually impossible to see it from the outside. Also, it being placed so close to the ear drum also makes it to generate high db levels of sound pressure close to ear drum. As a result, it can be fitted with a large number of hearing loss configuration. Not just that, it’s the only extended wearable hearing aid, which means you wear the device for 3 to 4 weeks continuously and you can take shower, go hiking, sleep with it! Its one the best solutions for people who suffer from tinnitus at night time, and they cannot wear hearing aids while going to sleep.
