Review: Amazing and works perfect as per expecatitions - I was not expecting that much good device while time of ordering. But its perfect working both ways The transmitter and receiver both ranges are good. And the biggest thing is that it works while you are connected to charging, thats what i was looking for. You can make your laptop or TV to transmit sound as bluetooth to your bluetooth headphone. And you can play your mobile sound on your non bluetooth car audio player with aux option, or normal spearkers that have only aux option but no bluetooth option.
Review: Good product - Good item
