Comfortable fit, absolutely stable during exercise (running).
Easy connection with mobile phone.
Long battery life. They last even during a marathon.
Sometimes there is a slight distortion in the sound, lasting 2 to 3 seconds.

Good value for money. They are waterproof and suitable for sports with very good sound quality and a battery life of 9-10 hours at about 15% volume (if the volume is increased, the battery life will definitely decrease, but personally I prefer not to lose contact with the environment). I am not fully satisfied with their application, but they have three sizes of ear tips for adjustment to the ears. They connect instantly and I have not noticed any disconnections, although some "hiccups" occasionally occur, which may be due to interference. The microphone is satisfactory. The headphones have magnets to stick together and prevent the cable from tangling.

I have them only to listen to music, they play loud and clear, from this perspective they are good for their money.
I have no opinion on conversation.

It constantly loses connection with the mobile phone and it is tiring, especially for someone who talks for several hours a day. I haven't encountered any other problems.

Good sound quality. After many pairings with the phone in order to fix it, the other person hears you after 5 seconds. The only downside.

The worst thing ever, really don't get them. I've had them for a month and in order for someone to hear me, I have to blow into the microphone and even then it doesn't always mean they will hear me. Such a shame, really wasted money, I recommend you don't get them!!!!
