Very very good.one time can listen music 6 hours. So far so good

The box charges them very fast, they are comfortable in the ear and do not bother for long periods. They don't have any noise cancellation, you don't mind the outside noise but they don't have this function. The sound is normal, not very bad or very good, they are heard just like Lightning EarPods headphones for example. It is not bad to buy in relation to quality/price.

Product: a good product, it sounds very good the finishes are fine and the battery I was worried about demomento can take no trouble. Quality/price good purchase

It's an excellent product. It meets all my expectations; They are very practical, comfortable and light. They're not annoying at all and they really do have noise cancellation (I read a comment that said No has noise cancellation),since even though it doesn't have rubber, the structure adapts very well to the ear and direction of the earphone allows for clear sound without so much ambient sound. In addition the low quality is very good for the size and price of the product; they don't vibrate at any time even if you go up to the volume. The battery lasted me between 7 and 7:30 hours with a volume of 70%. I haven't reloaded the powerbank yet and it still has more than half left with 3 charges. In conclusion they are a great choice for the type of hearing aids, since for the price you get a quality item, they give confidence since you have them in your hands. Totally recommended.
