Go to the store or fitting center, the cheap warranty is one or two years, the store's warranty is five years but the price is not cheap, the low price is not within this range. The most important thing is that after buying the machine, let alone two years, I don't want to wear it for a while. The store asked me to go back to adapt. I can still hear in a quiet place, but it's just noisy in a crowded and complex environment, and then I can only use it as a drawer machine. It's useless to buy it back. It's not that I don't want to use it, but I can't use it at all. There are many such users. We can't accept such users recently. No matter whether they have bought it for one or two years, they go to the original store to adjust it, but they can't adjust it. Every time they say they go back to adapt, but it's still the same, and then they don't wear it. Family members see that they don't wear it after buying it, and some of them let it go. Some think that the elderly can't hear directly, and then they come to our store to try it. After trying it, they know that hearing aids can hear so clearly and so comfortably. I can only grit my teeth and match a pair for the elderly. It's not that I don't want to adjust them. Some are domestic hearing aids, and the price is not less than 5,000 or 6,000 yuan each, but there is no room for adjustment because the technology is there. There are also many imported products, some are first-line brands and some are other brands. First-line ones are okay, but other types of machines are not worth the price at all, and the price is seriously high. There are also problems with the level of fitting. Many of them are just adjusting the size, and there is no fitting at all.
Hearing aids are useless no matter how many years the warranty is, because you can't use them at all after you buy them. Some people may hear, but many can't hear clearly. Some people hear very noisy and uncomfortable, but there is no way, just wear them, and finally become more and more deaf and less and less able to understand.
