I am able to take phone calls, listen to music, watch programs with my headphones in - while charging at same time! I can plug in an auxiliary cord and charge at same time in my vehicle!
They work! you can now watch your favorite youtube or netflix while charging the phone. Very friendly and reliable service. Will buy again in future.
This product is great since Apple decided not to put the usual headphone jacks in the 7plus. I can run music through this while charging.. I highly recommend getting it.
