QCY T1 => QCY T3 Quick Review
We used QCY T1 very satisfactorily and purchased this T3 product and tried it for a while today.
Sound quality: It's no different than T1 or T3 (I have never used an expensive Bluetooth earphone, so comparison with other products is -_-)
Wearing comfort: T3 was better than T1, comfortable fit
Durability: Runs along T1 Asphalt It works well even though it shakes twice on the floor
T3 is also running on the first use after purchase. I ran to the asphalt floor and it was scratching but it works well.
Volume: T1 is slightly larger at maximum volume than T1 and T3
Call quality: I think it's definitely better than T1. I just called and I did not hear anything.
Disadvantage: The QCY T1 is an analog button, so it has a click-through taste and it works right away
QCY T3 is touch-based, so there are many times when the touch is not good.
This was not good either, so it was easy to adjust the volume with the phone.
