Rechargeable digital nano device with noise cancellation (single) Advanced Technology: The MEDca Digital Rechargeable Earphones combine a streamlined design with luxurious, advanced features, allowing you to take control of your sound world. The compact design features a digital chip with noise cancellation and increased gain, while also reducing any annoying whistling/howling noises. Now you can enjoy crystal-clear sound wherever you want. Rechargeable and Reliable All-Day Performance: Battery operation can cost you in the long run, as you need to purchase and maintain a steady supply of batteries to keep your device running. This MEDca rechargeable device provides up to 25 hours of use on just one hour of charge. No other device comes close. One-Touch Operation for Effortless Convenience: We designed it specifically for seniors and older adults. One button controls everything—from power to volume. Perfect for those with arthritis or muscle weakness. Built-in notifications alert you when you've turned on the device and when it's time to charge. An LED indicator light reminds you. Unique L-Shaped In-Ear Design: Unlike BTE models that aren't compatible with glasses, can leave your earlobes sore, or ITE devices that can accidentally fall out while you're doing everyday activities like running, cycling, shopping, etc. Losing your device is such a hassle. Our L-shaped in-ear design fits snugly in your ears without discomfort, so you can wear them for longer periods of time and enjoy your favorite activities. A complete set of everything you need: This pair of MEDca fits both ears and includes its own charging dock. It also comes with 6 different sized ear tips, a cleaning brush, and a USB cable that you can connect to a power bank, laptop, or any compatible power source.
