The sound quality is really really good.And the buds looked very beautiful and attractive.Specially if you love red colour.The green-blue flickering lights made it more attractive. Voice quality on calls is not good. You have to speak a little louder than normal which is not feasible at most times. And there is a lot of noise on and off calls. Because of noise during calls, i had to disconnect the call in-between and talk through my phone. This is not why bought this wireless earbud. And after using it for nearly an hour, there is pain in my ears.
