hello before you continue reading this review it is necessary that you know that I am not an expert in headphones much less an expert in sound, I am simply an average user well I will start with the shipping of this product wow I was surprised how fast the delivery was I bought them around 12pm and they arrived around 6pm that same day wow incredibly fast well now let's move on to the headphones I will start with the case I ordered the gray color I would have preferred the white ones but they were not available at that time but to my surprise the gray color looks great, very nice it looks more formal so to speak so the case is good it is not that small but it is still comfortable to carry it in your pocket without problems now let's move on to the headphones in terms of comfort I have read many opinions and more than 80% are bad they all say that they do not fit well in the ear let me tell you that most of them are wrong let me explain when you insert them in your ear at first you feel that they do not fit well but the trick is to play with them turning them from right to left and from bottom to top until find the correct position for your ear you understand what I'm telling you believe me you will only do it once and it won't take you a minute to find the correct position for your ear and believe me after you find it you realize how really comfortable they are they don't fall unless you do some extreme exercise but tell me your Samsung said they were sports headphones? I don't think so or correct me if it is. I use them to go on public transport, to go to the supermarket, to walk to work, to listen to music at home while I do something, I use them to listen to a podcast before going to sleep, that is, I use them like a normal person would and they have never fallen out or felt the sensation of them coming loose, believe me, they are comfortable and they don't fall out. Finally, the sound is wow, the sound is very good, good bass, I love bass, if you don't like the bass to be so loud you can configure it in the application, well, as I said, I am a normal user and I really enjoy these headphones, obviously there are many more things you can do with them, voice commands, noise cancellation, real-time translation, but all of that can be found on YouTube explained by people who are dedicated to that, that's all I can say, these are excellent headphones, thank you Samsung and thank you Amazon
