Lively Life Ear Cuff Sound Amplifier

Cuff-type earbuds at first looked strange but people very soon realized that by applying less pressure on the ears and by allowing you to hear the environmental sounds as well, they are much better for long-time use. The Lively Life Ear Cuff Sound Amplifier takes the design and applies it to a special type of earphone: hearing aids. And the ear cuff design here proves even more helpful, since the people in need of such earphones like the elderly will welcome the extra comfort! With a size similar to a regular earbud of this type (2.5 x 2.7 cm / 1 x 1.1") and with a practical 4.8 x 6.7 cm (1.9 x 2.6") charging case, the Lively Life Ear Cuff Sound Amplifier uses an air conduction system for incorporating ambient sounds and conversations, so you won't feel detached from the world. With an average acoustic gain less than 35 dB and an equivalent input noise less than 32 dB, they amplify the sounds approximately 40 times and deliver them with an almost imperceptible latency of less than 15 ms for up to 20 hours so you can always communicate unobstructed!
