I live in nyc so if i am out in the street it is difficult for people to hear me through the mic even on less crowded streets

There seem to be issues with connectivity

With one of the pairs sometimes it seems the headphones cant sync with my galaxy s4 and the music is a little choppy and also in both sets i think the bluetooth gets a little weird in certain places mainly subway stations where the music will skip a little but i dont know if that is the phone picking up connectingdisconnecting to a weak cellular signal or if there is radio interference from the train equipment

This is my first bluetooth headphones purchase and so far so good but it seems the first set started going wonky after about six weeks i think the headphone drivers might be getting blown out the sound quality has gone down

One of the sets of headphones i purchased would not connect to the media on the device always said connecting but never actually did and the seller reached out and sent a replacement set free of charge
