headphone butten have a really slow response time

[bomboy2121]

i had my lg nexus4 and sennheiser cx275s for a long time and it has been working fine

now for some reason (and this is happning with all of my headphone/earphones with media butten so its probbly in the phone) the time it takes to switch song/awenser call/stop song is really long compherd to what it used to be and i cant start my music automaticly from sleepmode when im click the butten (which used to work for me)

help?
