Worked straight out the box which charges them... easy to pair up with my android phone... fit my ears perfectly and comfortable with no noise interference and a pleasant amount of bass... crystal clear sound
each bud produces a different feature from pausing to playing etc... simple and easy and small enough to be discreet and worn under a hat etc
charge lasts ages, can charge back in cute little case which also protects them or use the included cable
can't fault them, fantastic value too!
Everything I've ever purchased from poweradd has been of outstanding quality and Value
