Why put more? It is sold in supermarket about 39 then at this price I did not hesitate for long. Works great with my Samsung Ace 2. Good quality of listening and my parties hear me well. For comfort, nothing to say I changed the original rubber to put a smaller (additional 2 with different diameters are provided). It also comes with a car charger with micro USB plug, the plug delivers 700mA, the charger as my Ace 2, so I can recharge it with one or the other without fear.
