I've recently bought the QCY T2C and used it for a couple months. Here is a detailed review about it.
I find the overall sound quality of this earphone very good for $40. The sound is clear. The best thing about this headphones is it's base. It will not be as good compared to brands like Bose or JBL. It can also go very loud. But remember it's only $40. It's also very comfortable to wear in your ears since it's very light and fits your ear very well. You can select from 3 different earpiece of different sizes. I never actually tried wearing these in the shower or doing a waterproof test with it. I do a lot of sports with it and it is sweat proof. It is very good for sports since it doesn't fall out. It's also got some pretty good noise cancelling. Remember it is not active noise cancelling. It's the material that blocks out the sound. Now here are the down sides about this earphone. Although the sound quality is good, I find the Bluetooth range poor. I usually use this while playing basketball. I would put my phone at the side of the court. So just think of this. When you put your phone at the baseline for a basketball court and walk up to the top of the 3 point line, it starts to glitch and lag. Other then this I can't really find anything bad for this earphone. I've got the redmi airdots before which are really similar in price. They are similar in all aspects too but I feel like these ones have a better base and a better fit. At the end of the day, I would give this headphone a rating of 8/10.
