In fact the treble is slightly weaker than T1s. But it seems to be the best to listen to while exercising. It is light and small, so it gets a little less when exercising ~~ It touches well!
It sounds good. Sound quality is good. Definitely not Bluetooth.
Some people say that they are severely broken, but I do not have a break, and the sound quality is really good.
