You never think about your hearing. At least, not until you lose it. Then it’s the only thing on your mind. Our ability to hear connects us to the world, and most importantly, to the people we love. Over the last decade, the assault on our ears has been relentless through the non-stop streaming, video gaming, music festivals and video calls. And it’s not who you think that’s at risk—the World Health Organization predicts over 1 billion young adults 35 and under are in danger of hearing loss today. Because anyone can experience hearing loss, regardless of age. At Eargo, it’s our mission to change the way the world perceives hearing loss by making every aspect of your hearing journey as invisible as possible, so you never have to think about it. From the design of our devices, intuitive mobile app, extensive personalization options, rechargeable battery, lifetime customer support, Eargo is meant to amplify your life without compromising your lifestyle. Because this is the future of micro-hearing technology. Though the world is getting louder, hearing loss is a silent pandemic nobody is talking about. And Eargo was built to start a conversation about it, because life deserves to be heard. Eargo is designed for mild to moderate hearing loss. Will not restore normal hearing. Full benefit best obtained with frequent use. Visit Eargo.com/guides for more information and labeling.
