which is not effective which is in website and which product delivered and the sound system is too clumpsy while talking in phone the other person will not able to hear voice properly which makes an nusty sound and micro phone is not working along with that i can hear a beep sound when we connect to phone. I checked with my friends also for them also same issue occured. I checked earphones with other devices still same issue. so I would like to return the product. I don't like and this product which is useless and waste of time to send mail and discussing about this issue. along with that we need to send an attachment too. do you think we have much time to send you mail and wait for a long time for your reply. if we don't like we will return the product to return it will take details and it shows and error. why the hell you need to develop useless website. why customer has to send you a mail to return an product. why the hell playing with customers time.
