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 timeE***s - United States - Nov 10, 2024

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 itemc***u - United States - Jun 4, 2025
I have been working with Shen Rui for over a year now and it has been a very great process. The products are of amazing quality and the service, delivery, and customization really brings everything together nicely. Couldn't grow without them. Looking forward to a long term continuous partnership.M***R - Romania - Jun 4, 2025
The sound quality is outstanding—clear, balanced, and immersive across all frequencies. What made the experience even better was the excellent service from Max. He communicates very well, is extremely helpful, and responds incredibly quickly to every question. A truly smooth and professional experience from start to finish.
