So you have trouble hearing, especially in crowded environments? The iHEARHD can help. It is an invisible hearing aid at the size of a kidney bean that fits discretely inside your ear. It has 4 programs for you to cycle through in different environments.
The device comes with high fidelity 20-bit digital audio processing. Need something more powerful? iHEARMAX, which is a behind-the-ear hearing aid, is more suitable for people with mild to severe hearing loss. You can pre-order yours on Indiegogo.
