Very very very good Bluetooth headset has small budget and can surely see better than big brand to much more expensive bass and treble .Good super reliable but not put up too much otherwise there is such a kind of mix between and both listening but loses its subtlety crushes or do not compress it can .just a troublesome volumes and music buttons before hopping back that are the same and not very obviously but this grip .This is small brand will make its way to the mainstream.
