The delivery is very fast, probably because of the early agreement they are trying to make sure that the person receives it quickly and writes a review. By the way, I really liked the packaging, it was simply amazing, like some kind of luxury. This is my first time testing such modern headphones because I had them before, but they are not the kind that you even need to hold in your ear, and most importantly, the music sounds in the ears, but if someone talks to me, I can also hear them while listening to music. The sound quality is very good. Well, so far I really like everything about them. I have already tested them with them and they do not fall out. By the way, because I specifically cleaned them and you know they stay perfectly. The only minor drawback for me is that when you remove hair behind the ear, it constantly gets tangled behind them, but I will probably get used to it.
