1 Pair Digital Hearing Aids In-Ear Invisible Sound Voice Amplifier Rechargeable

Features
1. A common issue with sound amplifiers is hearing a lot of unnecessary noise. Issues like these can be prevented by having low noise equivalent output and noise reduction. Binaural hearing devices can transmit sound separately to each ear resulting in a clearer more distributed sound.
2.Compared to behind-the-ear (BTE) or in-the-ear (ITE) models, we offer a better hearing experience. The mini sound amplifiers allow you to hear natural high-quality sound while reducing background noise. They’re comparable to wireless earbuds in size. The small design fits in the ear and is almost invisible to the eye.
3.Changing batteries is a thing of the past. With the included portable charging case, you’ll be able to use our personal sound amplifier devices for up to 24 hours on a single charge. Constant replacing of batteries is not only costly but can also damage the device. By having their own charging case, our sound amplifiers have a continuous power source and provide a more stable performance.
4.Experience simplicity at its best with our latest hearing aid model – no programming required. Each purchase includes 2 personal sound amplifiers, 1 convenient charging box, and 1 USB to USB-C cable. Easily charge your device using the included USB to USB-C cable . Ideal for those on the move, its compact and lightweight design allows the case to fit seamlessly into your pocket, purse, pouch, or bag. Enjoy hassle-free, wherever you go.
5.Since they’re color-coded, you can easily tell immediately which one you need to put on. Red goes to the right ear and blue to the left ear. The charging case has a light indicator that tells you whether they are still charging or fully charged. Looks similar to a very popular mobile earbuds charging case.
