I also have the QCY T1C. Go for QCY if you want a more balanced sound. Go for the Tiso if you want a tad more bass and fun. The Tiso comes with 2 kinds of silicon tips. No foamies. It wasn’t really hard to get a seal. It is just that it is not very obvious how to put them your ears compared to the QCY. So i did it wrong the first few times. I like the sound of Tiso better but the QCY is easier to use cos the buttons are bigger.
