This product is on par with big brand names (and I have used several of them including Bose and Dr. Beats for over 6 months). It works just fine with cellphones and tablets. When turned on, it automatically connects to my cellphone every time after the initial set up. Voice quality for phone conversations is good; people at the other end could easily hear me. Wired connection is good as well.
