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.r***n - Israel - Dec 20, 2024

the attention, it was fast, the service was personalized, the product was of quality. I am super super happy with this supplierc***n - United States - Apr 23, 2025
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
