I ordered from AmazonE. Headphones that are obviously defective refuse to be replaced, they did not even offer this option. They shift the problem to the user's device, comparing it to the fact that they work without problems on an iPhone, although here the problem is clearly not in the device, but in the connection between the left and right earphones. Because headphones were planned to be used when doing sports on the street and traveling around the city, they do not perform their function. Before buying, I recommend thinking a few times. If there are problems, you will stay with her.
