No sound from right cup, Bluedio T3+, after a year using them once a week, Im Dj so I have very careful with my material, and contacto Bluedio, they have a fast response, but, they star asking for my Aliexpress buy number, o told them I dont know were is it, I buy so many things their, then they told me the problem was the cable, I told them I buy a new one, then they told me the warranty is just for 6 months, and they cant do anything, but if I find my Aliexpress buy number they give some discount for make a new buy, I prefere to order a new ones, but very bad posture by Bluedio!!
