Vista - Very good!
I was forced to do some serious research to find replacement earbuds for my Zolo Liberty+ (2 replacement pairs) buds that let me down.
Sound quality and fit are paramount to me.
Found several reviews about these and liked what I was reading. A bit steep on the price but thought hay! you get what you pay for right. Definitely the case (no pun intended) with these bad boys.
Only had them for a couple of months, but find the fit, the comfort, the sound, the app features....all what I expected and more.
