They arrived very well, without any blow or problems, they sound quite good, they are very comfortable, I will use them for recordings and production, they are extremely good, for the price I don't think there are better ones, they include some cables so you can use them with a microphone and without it, there is nothing wrong with them, I suppose that over time I will have to look for the replacements for the ear sponges like all hearing aids of this type, but the ones you have are excellent, they are soft, they insulate well and very comfortable, I am very satisfied with the purchase besides they arrived very quickly
