Features: Regain your confidence: MEDca rechargeable batteries are so small they are almost invisible. The design of being located entirely within the canal makes them so unobtrusive that most people don't even know they are there, requiring a closer look to see them. Neutral colors allow them to blend in with your ear canal. Never miss a word or ask people to repeat it. Excellent quality: Experience unprecedented crystal clearness again. This personal device reduces background noise without any annoying whistling or feedback, so you can hear every word even in noisy environments such as restaurants, classrooms, gyms, outdoors, and more. Consistent, clear, reliable, and delivered through our . Rechargeable! Long-lasting battery life: Battery-powered devices are cumbersome to use because you have a limited battery life. You won't receive any warning if the battery is running low, so your device could run out of power at any time. Our rechargeable PCs cannot. Charge in 4 to 6 hours and get up to 20 hours of use. The charging base acts as a portable power bank, allowing you to charge anytime and anywhere. Ready to use! NO PROGRAMMING: Designed to fit comfortably into the natural curve of the ear canal without slipping. They work right out of the box! Just put them on both or one ear, turn them on, and adjust the volume. This prevents the device from making a high-pitched squealing sound when turned on before plugging in. Choose from different earcup sizes to find your perfect fit. COMPLETE ACCESSORIES: Our goal is to make it stress-free and convenient, so these MEDca's will be the last pair you'll ever need. Each set comes with 2 (one for left ear and one for right ear), 6 earbuds (3 different sizes S/M/L), cleaning brush, wax cover, charging base and convenient carrying case. Take them with you wherever you go and enjoy life again! Package list: 1*Amplifier 1. Please allow some errors due to manual measurement. Please make sure you don't mind before bidding. 2.
