received this product on 3 March 2025, and ordered the product on 10 feb 2025. Use this product for 10 minutes now. It is Good for use but still compared to my other hearing aid it need to amplify more sound . I made it full volume and change modes also. Sound quality is good and soft .

This is a fabulous product, as my father, due to limited resources, used to refrain from spending €2000 on typical options. His friends say he is back in conversations and participates like he used to. The exceptional attention from the customer service team at Shenrui has been a gift for me and has also helped close friends who have ordered through me because they are older and do not navigate payment gateways well. Cheryl, in particular, has been the person who guided me through all my doubts and the entire process, making us more like friends than partners. I have nothing bad to say; it is a miraculous item

The hearing aids are amazing, great quality, great price. Even comes with an app that does a hearing test allowing you to set the hearing aids to your hearing. You can receive calls directly to the hearing aids via blue tooth from your cell phone. I have been using hearing aids costing 10 times what these cost, and these are close to being as good as the very expensive ones. Delivery was well within the promised time

This is hands down the most satisfying hearing aid supplier I've ever worked with in China. What makes them stand out is how seriously they take certifications, product quality, and delivery service. Unlike some smaller factories that slash prices but forget this is medical equipment needing real responsibility towards people with hearing loss, Jinhao actually cares. I really hope we can keep this partnership going strong for the long haul, and honestly, I also wish things between the US and China stay stable – it’s better for business all around
