A couple of weeks ago, I spent 9k on others to get things for my own personal use. The second generation has already reached 20 thousand, and the toad has been suffocated. The first Bluetooth drops I ever received: In most cases, yes, it will. It has a pleasant sound (but without wow effect). They are not easily dislodged and maintain their position properly. The noise reduction function makes the subway a tiny bit quieter, as if it were literally in the subway. However, their volume is not very high, and there are occasions when it is not sufficient within the same metro. The fact that these pins are touch-sensitive means that you can pause and skip tracks, which is a very convenient feature. If you turn on the speech recognition function, you still won't be able to hear the other person very well, and if you want to have a conversation with someone, you'll need to remove your headphones first. The speech recognition function is somehow stupid.
