I started to have issues with my hearing. Everything sounded like I was in a well and I heard a constant humming. I was having an issue hearing low tones. This hearing device has helped me so much. Especially when I am in a room where there is a lot of background noise. My hearing is clearer and the humming has reduced drastically. I like the case, it has a light on the front that indicates when it needs charging. I like the hearing aids as they are small and discreet. They have a little wire that I can pull them from my ears easily with. Each hearing device is labeled L&R and fits perfectly into my ear canals. Each hearing aid also has a volume control button and a wax guard. I like this device a lot and the battery life goes a long way. They are small, discreet, and comfortable. But more so they work very well and have helped improve my hearing drastically and allows me to lay in bed at night and watch television without a constant humming. I am so thankful for this company and they have the best customer service I’ve ever experienced. They are about pleasing their customers and helping me get the right hearing aid. I like this brand because if my hearing gets worse, I can move to another device. They also offer warranties on their devices and stand behind them. If I’m ever looking for another hearing device, I will definitely use CHOSGO!
