I use nokia BH 503 from last four years and believe me its out standing bluetooth headphones as compare to other once . No comparison with others .it have all functions control in volume up down, reverse forward, call pickup and cut, play pause.
it have a 3 to 4 hours battery backup.
but please avoid fake BH503 head phones present in the market there are lot of fake copied nokia headphones in the market so please buy it from nokia registered stores .
Thanks all of you
