I put 4 stars and not 5 because we feel that the key is a bit shoddy but apart from that the keg is yours Nikel well ds head the sound is good too. Testing on iPhone 4S.

Then the alumer and re press 2 times on the button and hold support until you see a blue and red blinking light. Then go ds your phone and the headset looking ..... Thank you amazon.
