I tired using the headphones (third party) on my iphone today, however when I went to plug them in it seemed like they would not go in all the way, I tried blowing in the jack to see if there was just some lint or dirt in the jack this did not help. Upon visual inspection it does not appear if there is anything blocking the jack. The headphones will only play part of the time rotating them seems to help. Sometimes they will not play at all and will stop the music that is playing. I have tried more then one pair to eliminate the issue being with the headphones. Any help is greatly appreciated
