and what they are better for sports, the price? The latter generally have permanent interruptions, no microphone, and the sound is weak in volume.
I have QCY QS1 (T1C). Interruptions are so rare that they do not spoil life with them at all. I think no more than the Irdotsov. The microphone is bad, in the room of norms, and on the street is not very, so I just use them as headphones, turning off
"Audio device phone". By the way, the Airdots in this regard are not very good either.
The volume of the sound is sufficient, and in rare records with a low level it is simply solved - using a player like
MX Player, there is the possibility of increasing the volume above the standard. You should not double up, but 50% and without distortion is enough for 100% of cases.
And they are very well kept in the ears, especially if you change the regular ear cushions.
