I bought this kit after having lost the one supplied with my phone (SE Aino), and I must say that I am fully satisfied, it works in much the same way. Keep the button pressed to end on / off the "touch" volume bar (which I find quite intuitive for me), the key to answer / dial the last number dialed ... As compared to the model I had concerns the display, text instead of diodes on the other ... Although more convenient to see who is calling! Regarding the sound I also found very correct with the supplied headphones. Its battery life is also very good! I just regret the load is via a micro USB input, my old kit to load onto the dock my phone ... Otherwise no complaints very good product! ;)
